RVs and WD-40: Unusual combinations that work!

Seems like every RV has at least a can or two of WD-40 for lubricating various parts. But there’s more use for old WD-40 than just the occasional thread loosening. Here are a few tips that may make for slicker RV trips.

Galley and household tricks:

Why on earth do RV manufacturers use light-colored carpets in RVs? Maybe they’re in cahoots with the carpet cleaning industry. But if you’ve got ink or other hard-to-lift stains in the carpet, here’s something to try: Hit the stain with a squirt of WD-40, let it stand for a couple of minutes, then use a sponge and warm soapy water to work over the stain. You may need to repeat a few times.

When we put our new RV vinyl floor in, we hadn’t even got our first road trip in when “you know who” left those nasty old heel scuff marks on the new floor. Too bad we didn’t know about the quick removal tip of shooting them with WD-40 and buffing them with a rag. Use plenty of ventilation if there’s a lot to remove.

If the stuck-on food in the RV fridge won’t come loose, then shoot it. Not the refrigerator – the stuck food, with WD-40. Wipe out the remains with a rag or cleaning sponge. Take after the area with soap and water before reloading the chiller with food.

Rattling down the road, it’s easy for “nested” glasses to get stuck together in an almost death-embrace. Don’t smack those glasses, squirt WD-40 around the rim of the stuck glassware, wait a few moments, and gently unstick ’em. And unless you’re the Tin Man of Oz, be sure to wash the glassware before taking a drink.

Does your barbecue need a resurrection? With time, grills can look like “death and Hades.” With a COLD, NOT LIT UP barbecue, shoot the grids down, wait, scrub with a wire brush.

Working around outside the rig:

Rig license plate looking a tad rusty? Spray with WD-40 and wipe away with a rag. Small amounts of rust will come free, and new rust will be discouraged from settling in. Too bad it doesn’t wipe out the high cost of license tab renewals!

Got stickers stuck on your bumper – or elsewhere on your rig where you don’t want ’em? Phaser-blast the offending “cling-ons,” with WD-40, let ’em sit for a minute, then wipe them off. Really hard ones may require more than one application and a gentle nudge with a plastic scraper.

Did your RV come from the dealer lot loaded with window stickers? Don’t scratch the glass – or the UV blocking film. Shoot the offenders, wait, then use a plastic scraper to remove.

Bug splats on the grill of your tow vehicle or the end cap of your rig will come off easier if you “pretreat” the areas with WD-40. Newly smooshed bugs may slide off on their own, or be convinced to come free a whole lot easier than without treatment.

Mechanical tricks:

Greasy hands but no hand cleaner? Shoot a bit of WD-40 on your hands, rub together, then wipe off with a rag or paper towels. Follow up with water and soap.

Got a stuck spark plug in the generator or tow vehicle engine? A shot of WD-40 near the threads, allowed to soak in, will often loosen a stuck plug.

Rainy day hard-start problems? Sometimes humidity can creep into ignition wires. Spray WD-40 on the plug wires and try starting again. WD-40 can displace the unwanted moisture, helping the free flow of healthy electrons.

Did your motorhome or tow vehicle do a “doo-doo” on your concrete driveway? Shoot oil or tranny fluid drips copiously with WD-40, brush with a stiff brush, then shoot the whole mess with a high-pressure stream from a garden hose.

Use a bed liner on your pick-em-up truck? Before you slide in that bed liner, spray the bed thoroughly with WD-40. When you need to pull the bed liner back out, it’ll come out much more easily.

And others you never would’ve thought of:

Got your fingers stuck in the glue? Grab the WD-40 and shoot a bit on your stuck pinkies, rub them against one another until they’re freed up. It’ll take glue off other places where you don’t want it, too. Shoot a little on a rag and rub away.

As RVers, all of us are soooo careful about cleaning up after Rover, right? Well, sometimes the neighbors don’t read the memo, and hey! You’ve got something on your shoe you don’t want there. If your tennis shoes get doo-dooed, spray with WD-40, and use the dog owner’s tooth brush to clean the crevices. Rinse off under the tap and let ’em dry.

Get too close to another car and now you’re “mixing paint”? A paint rub from another vehicle can often be removed by shooting it with WD-40, letting it sit for a half-minute, then buffing down with a clean rag.

Got bugs? If you don’t have a can of Raid available, shoot those bugs directly with WD-40. If the critters insist on returning despite this warning, shoot a little around screen and door frames, but NOT if there are little ones or babies around!

Editor: Here’s a link if you want to stock up on WD-40 from Amazon. (Did you know it’s available from pen-size to gallon-size?)

Lot of good tips. One definite DO NOT DO is use WD-40 on your tires. Think for a moment about the ability to dissolve sticker glue. This shows what the WD can do to your tire rubber….Dissolve some of it and definitely dissolve and remove the oils and waxes we put in your tires to make them last.

Good (and important) to know! Thanks, Roger! 😀 —Diane at RVtravel.com

I do see perhaps some situations where I might use WD-40, but NEVER around anything that food would be associated! My Dad was a locksmith & sometime had to fix car door locks as people shot WD-40 into them & the stuff just attracted dirt over time & made the lock useless!

I do not even own a can of WD-40. I use the correct lubricant for the job at hand.

While these ideas work, use caution on any plastic or rubber. WD40 will soften and ruin them over time. Same goes for Go-Gone. Mike even mentions this in his articles…

Don’t use WD-40 as an oil substitute. It is basically a solvent, and will dry up in no time. Once you’ve used it to loosen or stop squeaking or get a mechanism moving, apply the right type of oil to prevent wear.

Works great on keeping my motorhome HWH jacks cleaned and lubed.

My hand crank stabilizers got to the point where when I cranked them down (or up) , especially when using my drill, they screeched loudly. Another RV’er came over and suggested that I spray the ‘worm gear’ with WD-40. Don’t worry, he said, it won’t collect dirt or dust. So I blasted the gears with WD – and VIOLA! No more noise. So far, twice a year seems to be sufficient to keep the noise at bay.

I use bicycle chain lube on mine. Seems to work well.

Bike chain lube is KING of lubes – good tip Snayte
And the one in this article about removing food stains in the fridge – NO NO No do not do that. The petroleum chemicals in WD-40 will be very hard or impossible to erase as it may depending on the type of plastic lining the fridge absorb into or even stain it.

Same for using it to remove a stain in the flooring. Best remove shoes before stepping inside.. We’ve owned many RV’s over the past 50 years and the flooring/carpet in each one has remained like new for us to enjoy and for those who come after us lucky to get a second hand rig that’s been respected and cared for!

Bottom line – I’d never use WD-40 or anything like it inside my home or RV.
