I am a professional carpet cleaner. Using WD 40 on normal stains isn't going to work but we use it on oil or grease stains all the time with GREAT results! I had a customer call me after she just had a brand new trailer home set up and one of the movers brought in grease on their boots. Brand new carpet with lots of grease stains on it. We got them out with a scrub and WD40 and it looked brand new again :) Good luck!

I would highly recommend that no one use this for cleaning floors unless you want to go see a chiropractor for your back when you go ass up

I noticed that for many of your experiments you sprayed on WD40 and immediately wiped it, so of course it didn’t work. I can tell you that tape WILL come off surfaces, such as a fridge, if you give it time to soak in. Also, sometimes you need to use a hard edged tool for lifting paint etc, rather than just a cloth. Would have loved to see you try to clean a toilet with WD40. You said why bother when there are other cleaners. However, it might be a good substitute if you run out, and if it does work it would save you having to buy toilet cleaning products.

You need a regular wash rag (terrycloth, cotton, etc) to clean off decal/tape residue. Paper towel and microfiber cloth doesn't do that very well.

I coat my shovels with WD40 before every winter. When I shovel snow it slides right off.

wd-40 can't make your knuckle half its size

I like WD for squeaks of course, but also for shining the stainless steel kitchen sink. Clean sink first then dry. Baby oil also works for polishing the sink, but does not last as long. Thanks for the review. 😀

The problem with the paint on the board removal is that latex paint takes at least 21 days to completely bond and cure to any surface much less or glossy piece of paneling. A better test would’ve been too sand the wood first to rough it up then do your test.

I don't understand even trying with vinyl to test whether it can clean grout. They're completely different materials that have nothing to do with each other except that we've made vinyl flooring that looks like tiles & grout.

Also, with the paint on wood - I'd have liked to see an attempt to remove the non-treated side by peeling prior to applying the WD-40.

My windows sometimes gets stuck, mostly in winter, I live in Austria, the weather is cold and wet in winter, it safed me from sitting with a stuck open window in the middle of the night, I love it.

best rust removal is soak it in vinegar for 24 hrs . falls off. also wd 40 is used for plastic car trims to make them black again. eg bumpers.

I use WD40 to clean the stickers & glue from glass & plastic bottles, clean cars wiper blades, Remove Rusty screws, clean Road tar from Vehicle, Remove bird poop on car, clean head lamp and a fire starter.

Used it to soften and remove old silicone sealant around bath and shower when replacing seal.

In the old days of incandescent bulbs that got hot, WD helped to keep the metal screw thread from sticking…

Removing sticky residue left after removing stick-on label from glass.

The rust removal WD-40 can do is useful for things like cleaning off rusty bolts (on a car, e.g.) as you're working with them. Not only does it help get them unstuck, it cleans off some of the surface rust to make reassembly easier. (In my experience, anyway.) I wouldn't expect it to remove that much rust.

Another use for WD-40 that fits with its original water-displacing function is preventing door locks and moving parts from freezing in winter! Now we have fobs to unlock our car doors, but I used to use the red straw to spray WD-40 into the keyhole every winter (as needed), and apply it to latches & other parts, like the handle, that might freeze shut.

Well it was designed as a water dispersant. That’s the way I understood. There were other formulas. WD 40 was number “ 40” of the formula. Yes it has other uses as many other chemical compounds do, however it was originally designed for
water dispersant.

Good video. Thanks for posting. I use it a lot for cleaning my hand when I get grease or paint on them. Leaves the hands not dried up like many hand cleaners. With the salty roads up here, every fall, I spray all the under-hood wiring & connectors on my truck with the WD40. Helps prevent moisture. WD - Water Dispersing, 40 - 40th formula. Best Regards - Mike

Hi. You should allow the cleaner a chance to work. You need to let it set for 1-2 minutes and then try it. Most people, myself included spray and wipe down right away. It has to sit to get the best results.

This use for WD40 is a bit like feeding strawberries to pigs! Kerosene is a regular product used in industry when machining aluminium, as it stops material sticking to cutting tools and cools the tool and the job. However, not many of us keep a supply of kerosene. I flatly refuse to believe that any handyman worth the title, doesn’t have a can or two of WD40 in his tool kit. WD40, etc is the perfect substitute for kero and, being in a pressure pack, is far more convenient to use. So next time you’re drilling or cutting aluminium, give the drill bit or hacksaw blade a regular squirt of WD40.
