How to Clean and Maintain a Spare Tire Cover

A spare tire cover protects your spare tire from sun, weather, and road debris — but it also needs a little care of its own. Cleaning it the right way not only keeps your vehicle looking better, it also helps the cover last longer and continue protecting your spare.

Here’s a simple guide to cleaning and maintaining your spare tire cover, especially if it’s a high-quality vinyl cover like SpareCover®.

Use Mild Soap and Water Only

The safest way to clean a spare tire cover is with:

• Mild dish soap

• Warm water

• A microfiber cloth or soft sponge

This combination removes dirt, pollen, salt, and road grime without damaging the vinyl or printed design.

Avoid harsh detergents or abrasive cleaners — they can weaken the vinyl or remove the protective finish.

Never Use Petroleum-Based Products

Avoid products like:

• Armor All

• Tire shine

• Silicone sprays

• Petroleum jelly

• Harsh solvent cleaners

These can cause:

• Surface cracking

• Vinyl discoloration

• Sticky residue

• Breakdown of the protective coating

• Long-term fading

Marine-grade vinyl is designed to be durable on its own — it doesn’t need chemical shine products.

Rinse Dirt and Dust Before Wiping

Before scrubbing, rinse the cover with clean water.

This prevents:

• Scratches

• Micro-abrasion

• Grinding dirt into the vinyl

A simple hose rinse loosens surface grime and makes cleaning easier.

Use a Soft Cloth — Never a Brush

Brushes can scratch or dull the finish.

Always use:

• Soft microfiber

• Soft cotton cloth

• A non-abrasive sponge

Avoid:

• Stiff brushes

• Scouring pads

• Rough towels

Gentle cleaning keeps the cover’s finish smooth and looking new.

Avoid Pressure Washers

Pressure washers can:

• Force water under the cover

• Peel printing

• Damage vinyl

• Loosen elastic edges

Light hose pressure is sufficient for routine cleaning.

Dry the Cover Completely

After washing, dry with a soft towel or let it air dry.

This helps prevent:

• Water spotting

• Mildew

• Streaking

Vinyl dries quickly, so it only takes a few minutes.

Clean Off Road Salt After Winter Driving

If you live in a snowy region or drive on salted roads, winter debris can build up on your spare tire cover.

Salt causes:

• Surface staining

• Vinyl wear

• Hardware corrosion around the tire mount

A quick rinse every few weeks during winter prevents long-term damage.

Avoid Parking with the Cover in Direct Sun When Possible

Marine-grade vinyl is UV resistant — but nothing lasts forever in full sun every day.

Parking in:

• Shade

• Garages

• Carports

…helps extend the lifespan of the cover and the spare tire underneath.

Inspect Your Spare Tire Cover Periodically

Check for signs of wear, such as:

• Cracking

• Fading

• Peeling print

• Loose elastic

• Torn seams

Catching problems early prevents damage to the spare tire.

How Often Should You Clean a Spare Tire Cover?

It depends on your climate and driving:

• Every 2–4 weeks in dusty or coastal areas

• Every month in normal conditions

• After off-road trips for trail vehicles

• After winter storms to remove salt

Regular cleaning keeps the cover looking fresh and functioning properly.

Final Thoughts: Proper Care Keeps Your Cover Looking New

Cleaning a spare tire cover is simple, but it goes a long way in preserving the appearance and protection it provides. Using mild soap, avoiding harsh chemicals, and maintaining it regularly ensures your cover stays durable, flexible, and looking great for years.

A high-quality SpareCover® already lasts longer than cheap alternatives — with proper care, it lasts even longer.
