Whatever you do, don't do this to your tire cover ....

Use the following cleaning method at your own risk, as the vinyl manufacturer does not officially recommend using a washing machine.

• Pre-treat: Apply ZEP degreaser or an equivalent product to the soiled areas.  I suggest avoiding a brush for this step.

• Setup: Turn the cover inside out, just as it was initially shipped.

• Wash: Use warm or hot water with a double dose of laundry detergent.  Adding OxiClean is helpful for white covers.

• Spin: Use a very slow spin cycle or no spin at all.  

• Dry: Use a dryer on low to medium heat, or let it air dry overnight  

• Protect: Once completely dry, reinstall the cover and apply a silicone-based vinyl protectant to defend against UV rays.

If any spots remain after the first wash, try applying bug and tar remover using a green dish sponge, then repeat the wash and dry cycle. Please note that repeated applications of harsh cleaners and machine washing will reduce the life of the vinyl.

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.
