Why Jack and Block Maintenance Matters for RVers

Leveling jacks and stabilizers support thousands of pounds of static weight, while plastic blocks distribute that pressure across unpredictable terrain. Dirt, gravel, and road salt act as grinding paste on metal telescoping shafts, wearing down hydraulic seals or stripped gears on electric stabilizers. When these components are ignored, the friction increases the amp draw on electric motors, leading to blown fuses or burned-out motors.

Seized jacks leave RVers stranded, unable to hitch up or safely hit the road. Furthermore, dirt-caked plastic blocks hide hairline cracks that can fail catastrophically under load, leading to sudden tipping hazards or structural damage to the RV frame. Routine cleaning and inspection are the easiest ways to protect your safety and your wallet.

Heavy-Duty Degreaser – Simple Green Industrial Cleaner

Road grime, grease, and hydraulic fluid accumulate on jack legs and feet, forming a sticky paste that traps abrasive dirt. A powerful degreaser is essential to cut through this buildup without eating away at rubber seals, plastic footpads, or the surrounding environment. Traditional solvents can damage the undercoating of your rig, making a balanced cleaner necessary.

Simple Green Industrial Cleaner and Degreaser is the ideal solution because it is biodegradable, non-corrosive, and incredibly effective on petroleum-based grease. This concentrated formula can be diluted to match the severity of the grime, saving precious under-bay storage space by eliminating the need for multiple single-use cleaners. It rinses away clean without leaving a residue that would otherwise attract new trail dust.

Always dilute this formula according to the instructions, as using it full-strength on certain aluminum parts for extended periods can cause staining. This cleaner is perfect for full-timers who camp in natural settings where eco-friendly runoff is non-negotiable, but it is not for those looking for a quick, aerosol-spray-and-forget solvent that requires no water rinse.

• Concentrated, biodegradable formula safe for campground disposal
• Non-abrasive and non-corrosive composition that protects metal surfaces
• Safe for rubber seals and O-rings commonly found on hydraulic rams

Wire Scratch Brush – Linzer Carbon Steel Wire Brush

Rust is a constant threat to steel stabilizers and scissor jacks, especially for those who frequent coastal regions or winter climates. Before applying any lubricants or protective coatings, you must physically strip away loose rust scale and baked-on mud that a standard wash won’t budge. Leaving rust under a new layer of paint or lube only accelerates the decay beneath.

The Linzer Carbon Steel Wire Brush features stiff, oil-tempered carbon steel bristles that strip away oxidation without bending out of shape. Its ergonomic wooden handle provides a secure grip when working under the rig, and the built-in scraper tool on the tip is perfect for chipping off hardened road tar. It is durable enough to handle aggressive downward pressure without shedding bristles.

Do not use this aggressive wire brush on chrome-plated hydraulic shafts, as it will scratch the surface and ruin the hydraulic seals; limit its use to painted steel frames, scissor jacks, and footplates. This tool is essential for owners of travel trailers with manual or electric scissor jacks, but it is overkill for rigs with high-end, polished hydraulic leveling systems.

• Durable carbon steel bristles designed for aggressive rust removal
• Integrated steel scraper tip for clearing hardened road tar and clay
• Ergonomic solid wood handle with a pre-drilled hang hole for easy storage

High-Pressure Hose Nozzle – Bon-Aire Original Ultimate

Blasting off thick cakes of mud and road salt from undercarriage components requires serious water pressure. Without a dedicated high-pressure nozzle, you are stuck wasting water and time trying to scrub away heavy debris by hand in tight, uncomfortable spaces. A strong stream does the heavy lifting before any hand cleaning begins.

The Bon-Aire Original Ultimate Hose Nozzle is constructed from heavy-duty die-cast aluminum and features a fire-hose-style rotary dial that adjusts from a gentle mist to a powerful jet. It delivers the concentrated force needed to clear debris from jack hinges and block honeycomb structures without requiring a bulky, space-consuming pressure washer. Its rugged rubber bumper protects it from cracks when dropped on asphalt.

It is built to last a lifetime, but its solid metal construction makes it relatively heavy, and it can leak if the internal rubber washers are not kept in good condition. This nozzle is perfect for RVers who rely on standard campground water hookups but need maximum cleaning power, though it may not perform as well on low-pressure well-water systems.

• Heavy-duty die-cast aluminum body wrapped in a protective rubber guard
• Adjustable fire-hose style spray pattern from fine mist to jet stream
• Dual shut-off design for leak-free operation on any standard garden hose

Dry Silicone Lubricant – WD-40 Specialist Dirt & Dust

Metal-on-metal friction will quickly wear out your leveling jacks, but traditional wet greases are a magnet for road dust and sand. A dry lubricant is essential because it provides necessary friction reduction while drying to a clear, non-sticky film. This ensures that road debris blows off rather than sticking to your mechanical parts.

WD-40 Specialist Dirt & Dust Resistant Dry PTFE is the premier choice for RV jacks because it dries exceptionally fast and handles extreme temperatures without breaking down. The Smart Straw design is incredibly useful for flipping up to spray deep into scissor jack threads and flipping down for wide-surface coverage on stabilizer legs. It provides excellent corrosion protection without creating a messy paste.

Ensure the jack surface is completely clean and dry before spraying, as applying silicone over existing dirt will trap abrasive particles against the metal. This lubricant is a must-have for boondockers who frequent dusty desert environments, but it is not a replacement for heavy-duty marine grease on slide-out gears that require high-load paste.

• Dries to a clear, non-staining film that actively repels dust and dirt
• Wide temperature range of -100°F to 500°F for extreme travel climates
• Smart Straw system for precise pinpoint spraying or wide-angle coverage

Rust Reformer Spray – Rust-Oleum Rust Reformer

Once rust takes hold on steel jacks, washing alone will not stop the corrosion process. A rust reformer is needed to chemically convert active rust into a paintable, protective barrier, halting structural decay in its tracks. This eliminates the need to sand down to bare metal on hard-to-reach stabilizer frames.

Rust-Oleum Rust Reformer is the industry standard for mobile applications because it bonds directly to rusted surfaces and transforms them into a flat black, protective finish. This aerosol spray is highly effective for reaching the tight crevices and undersides of leveling jacks that are difficult to paint with a brush. It prevents future rust from forming while making your undercarriage look clean and maintained.

You must scrape off loose paint and flaking rust with a wire brush before spraying, and it requires a full 24 hours to cure before exposing the jacks to moisture. This is an indispensable tool for owners of older RVs or trailers used in snowy, salt-treated winter conditions, but it is unnecessary for aluminum leveling components.

• Instantly converts rust into a paintable, protective polymer barrier
• Dries to a durable flat black finish that matches most RV undercarriages
• Aerosol spray can format for easy access to tight mechanical joints

UV Protectant Spray – 303 Marine Aerospace Protectant

Plastic leveling blocks sit under intense sunlight for weeks or months at a time, making them highly susceptible to UV degradation. Over time, solar exposure leaches plasticizers, causing the blocks to fade, become brittle, and shatter under the weight of the rig. A quality UV protectant acts as insurance for your plastic investments.

303 Marine Aerospace Protectant acts like SPF 40 sunscreen for your plastic and rubber gear, offering unmatched resistance against fading and cracking. Unlike cheap silicone sprays that leave a greasy residue, 303 dries to a clean matte finish that repels dust, dirt, and water spots. It chemically bonds to the plastic to keep it flexible under heavy load.

It must be wiped completely dry after application; leaving it wet on plastic surfaces can lead to streaks and reduce its protective lifespan. This is a crucial product for RVers who spend winters in sunny climates like Arizona or Florida, but it is less critical for those who exclusively use heavy-duty wood blocks or steel outrigger pads.

• Powerful UV blockers prevent fading, hardening, and premature cracking
• Dries to a non-greasy, anti-static matte finish that won’t attract dust
• Safe for high-impact plastics, rubber, vinyl, and fiberglass surfaces

Heavy-Duty Storage Tote – ToughBox 17-Gallon Cruiser

Storing damp, dirty leveling blocks and cleaning supplies directly in your RV’s pass-through storage bay is a recipe for mold, rust, and unwanted odors. A dedicated, sealed heavy-duty storage tote keeps contaminated gear isolated from your clean living and camping supplies. It also makes setting up camp faster by keeping all leveling gear in one grab-and-go location.

The ToughBox 17-Gallon Storage Tote is built from industrial-grade polypropylene that can withstand the crushing weight of heavy plastic blocks and metal tools. Its recessed lid allows for secure stacking in tight basement bays, and the snap-fit lid keeps dust and pests out while containing residual odors inside the tub. The heavy-duty structural walls will not bow when packed tight.

Ensure your plastic blocks are mostly dry before sealing the lid for long-term storage to prevent mildew growth inside the tote. This 17-gallon size is perfect for standard 10-pack block sets and cleaning chemicals, making it ideal for space-conscious Class C and travel trailer owners, but larger Class A rigs might require multiple units.

• Impact-resistant plastic construction that resists cracking in freezing weather
• Secure, snap-fit latching lid with padlock holes for added security
• Stackable design with deep channels that prevent sliding in transit

Scrub Brush – Libman Heavy Duty Scrub Brush

Cleaning the intricate honeycomb undersides of plastic leveling blocks requires physical scrubbing action to dislodge packed dirt, gravel, and mud. A high-pressure hose can only do so much; a stiff-bristled brush is needed to break the mechanical bond of dried clay and grit. Without it, you are simply washing over packed dirt.

The Libman Heavy Duty Scrub Brush features extra-stiff polymer bristles that resist collapsing under heavy scrubbing pressure. Its pointed nose is perfectly shaped to reach into the tight corners and small square voids of interlocking leveling blocks, while the ergonomic rubber-grip handle prevents hand fatigue. It stands up to harsh cleaning chemicals without degrading.

Avoid using this brush on delicate painted or chrome surfaces, as the stiff bristles can cause minor scratching. It is a must-have tool for any RVer who camps off-grid on dirt or clay surfaces, but it is less necessary for those who stick strictly to concrete RV resort pads.

• Stiff, long-lasting polymer bristles designed for heavy agitation
• Pointed brush shape specifically designed to clean tight corners and pockets
• Ergonomic non-slip rubber grip handle for comfort when wet

Protective Work Gloves – Mechanix Wear Original Gloves

Cleaning road grime, dealing with rusty steel, and handling heavy plastic blocks can take a serious toll on your hands. Standard latex gloves tear too easily, leaving your skin exposed to harsh chemicals, sharp metal burrs, and skin-drying road salts. A durable, tactile pair of work gloves is essential for safety and comfort.

Mechanix Wear The Original Work Gloves strike the perfect balance between heavy-duty hand protection and the fine tactile sensitivity needed to feel for tiny hydraulic leaks or pin alignments. The synthetic leather palm provides excellent grip on wet tools, while the breathable TrekDry material keeps hands cool and comfortable during hot summer maintenance sessions. They are machine washable, making them easy to clean after a dirty chore.

These gloves are water-resistant but not completely waterproof, so they will eventually soak through if submerged during heavy washing tasks. They are ideal for any RVer who does their own maintenance, but they are not suitable for handling high-heat components or heavy welding tasks.

• Durable synthetic leather palm for excellent grip and abrasion resistance
• Breathable TrekDry material back keeps hands cool and dry

How to Safely Wash and Dry Plastic Leveling Blocks

Cleaning plastic leveling blocks requires a systematic approach to ensure longevity and safety. Start by knocking off large chunks of dirt and mud against a hard surface before wetting them down. Apply a diluted mixture of eco-friendly degreaser and scrub thoroughly with a stiff brush, focusing heavily on the honeycomb chambers where gravel, pine needles, and mud tend to wedge themselves.

Once scrubbed, rinse the blocks thoroughly with a high-pressure nozzle until the runoff water runs completely clear. Crucially, never store plastic blocks wet; trapping moisture inside a dark storage tote promotes mold and mildew growth that can degrade the plastic structure over time. Lay the blocks out in a single layer in the sun for an hour, flipping them once to ensure both the flat top and the hollow underside are completely dry before packing them away.

Establishing a Routine RV Leveling Maintenance Schedule

Consistency is the key to preventing leveling system failures on the road. A solid rule of thumb for full-time RVers is to perform a quick visual inspection every time you hitch or unhitch the rig. Look for signs of hydraulic fluid leaks, bent stabilizer arms, or hairline cracks in plastic blocks. A deeper cleaning of the jack shafts and lubricating pivot points should occur once every three months, or more frequently if you are traveling through coastal areas or dusty desert landscapes.

Integrate this chore into your seasonal deep-cleaning checklist. Before winter storage or transitioning to a new long-term campsite, dedicate an afternoon to treating rusty metal with reformer spray and coating plastic blocks with UV protectant. By treating your leveling system as a critical life-support component of your mobile home, you will ensure stable, safe, and stress-free setups for miles to come.

Conclusion

Maintaining your RV’s leveling jacks and blocks is a simple task that yields massive rewards in safety and long-term savings. By investing in the right tools and committing to a consistent maintenance routine, you protect your rig’s foundation from premature wear. Keep your gear clean, dry, and protected, and your home on wheels will remain rock-solid wherever the road takes you.
