Care
How to Clean and Maintain a Spare Tire Cover (Material-by-Material Guide)
touko
Spare tire covers do not need much maintenance, but they do need the right kind when they need it. The most common reason a cover ends its life early is not weather or UV — it is the wrong cleaning method. A pressure washer on the way out the door after a muddy weekend. A wire brush on stuck-on grime. A bottle of solvent that “just dissolved everything” on a printed design. We see all of these.
The good news is that the right routine is unusually simple. The same gentle approach works across every material we make — Polyester, PVC, PU Leather, and Marine Grade Vinyl (including the Anti-Theft Kit version). Mild soap, lukewarm water, a soft cloth, a thorough rinse, and air drying. That is the entire method.
The other thing worth knowing is that a small amount of regular care meaningfully extends cover life. A monthly rinse on a coastal vehicle. A twice-a-year UV protectant on Marine Grade Vinyl or PU Leather. These take a few minutes and add years.
Here is the care guide that applies across the catalog.
Pressure washing is not recommended for any Wheel Shell cover, regardless of material. Clean with mild soap, lukewarm water, and a soft cloth. Rinse thoroughly and air dry. The same routine works on Polyester, PVC, PU Leather, and Marine Grade Vinyl.
The cleaning method (works on every material)
- Mix mild soap with lukewarm water. Dish soap works well. Skip degreasers, solvents, and anything labeled “heavy duty.”
- Apply with a soft cloth or microfiber. Work in the direction of the print, not against it. For stubborn dirt, a soft-bristled brush (toothbrush-grade) is the upper limit.
- Rinse thoroughly with a regular garden hose at standard pressure. Soap residue dulls the finish if it dries on the cover.
- Air dry off the spare when possible. Trapping moisture between a wet cover and a warm tire can leave water spots.
- Reinstall once dry. The cover should sit flat, with the drawcord or elastic band fully seated.
Polyester
Polyester is lightweight fabric. Wipe with a soft cloth, mild soap, and lukewarm water. Air-dry fully before reinstalling. Heavy soiling responds to a soft brush in the direction of the print, followed by a hose rinse at standard pressure.
PVC
PVC has a smooth, easy-clean surface that handles mud and dust well with a sponge and mild soap. Brush debris, road grime, and tree sap all come off with the standard routine described above. No pressure washing.
PU Leather
PU Leather has a delicate matte-finish surface. Use a soft microfiber cloth, mild soap, and lukewarm water. Apply minimal water to the surface — PU Leather is water-resistant, but prolonged soaking can affect the finish over time.
For protection, apply a thin layer of vinyl protectant (303 Aerospace or Armor All Original) every 6–12 months. This restores the matte black finish and adds a UV barrier.
Marine Grade Vinyl (and Anti-Theft Kit version)
Marine Grade Vinyl is the most durable material in the catalog. For routine cleaning, mild soap and a soft sponge are enough. Marine Grade Vinyl resists mildew, salt, and tree-sap staining. If you live near the coast or in salt-air country, rinse the cover monthly with the garden hose at standard pressure to keep the finish at its best.
A vinyl protectant (303 Aerospace or Armor All Original) every six months helps the matte finish hold its look across the up-to-5-year lifespan.
What to avoid on every material
- Pressure washers. Not recommended on any Wheel Shell cover, regardless of material.
- Bleach. Degrades the print and the substrate.
- Solvents (acetone, brake cleaner, paint thinner). Strips the print and dulls the finish.
- Abrasive scrubbers (steel wool, wire brushes, scouring pads). Scratches the print and the surface.
- Hot water. Lukewarm or cold is fine. Hot water (above 120°F / 49°C) can soften vinyl over time.
- Direct sunlight while wet. Trapped moisture under a wet cover on a hot tire can cause water spots. Air-dry off the spare or in shade.
Frequently asked questions
Can I pressure wash my spare tire cover?
No. Pressure washing is not recommended for any Wheel Shell cover, regardless of material. Clean with mild soap, lukewarm water, and a soft cloth. Rinse thoroughly and air dry.
How often should I clean my spare tire cover?
Daily-driver covers typically need cleaning every 1–2 months. Trail rigs and overlanding builds clean as needed after muddy days. Coastal and salt-air vehicles benefit from a monthly rinse.
Can I machine wash a spare tire cover?
No. Machine washing damages the print, distorts the cover shape, and breaks the elastic or drawcord. Hand-clean only.
My cover has a stain that will not come off. What should I try?
For most stains, a soft brush with mild soap and lukewarm water, worked gently in the direction of the print, lifts the discoloration over a couple of passes. For PU Leather, a vinyl-safe degreaser applied gently. For Polyester, light dabbing with a stain remover — avoid bleach. If the stain persists, reach out: we replace defective covers free within 30 days.
Can I use Armor All or vinyl protectant on the cover?
Yes — on PU Leather and Marine Grade Vinyl, a thin coat of vinyl protectant (303 Aerospace, Armor All Original) every 6–12 months restores the finish and adds UV protection. Avoid silicone-heavy protectants on Polyester (they can leave a residue).
