WD-40 Long-Term Exposure Testing on Rubber Parts (Experiments Ep.2)

We set up an experiment to test the effects of WD-40 on various rubber parts over a period of 15 months in a controlled manner, with some interesting results! There is a lot of examining of parts, explaining ideas and theories, and comparing results with different types of rubber to what the manufacturer of WD-40 claims. Wanted to test this out because I have heard very frequently that WD-40 destroys rubber but hadn't seen much real testing or proof of it.

This is a first, this video was uploaded a few hours ago and commenters brought it to my attention that there was a constant audio buzz throughout the video. Thank you to commenter Mason Thrill and others for pointing it out! For whatever reason it was basically inaudible on the speakers hooked up to my computer setup but extremely audible when played through headphones or phone speakers. Some sort of interference/static from the microphone setup used. After a little bit of noise removal the video was re-rendered and re-uploaded and I believe that the buzz is gone, to the best of my ability to hear it/remove it. Sorry to the dozen people who commented on the first upload, I will try to make sure this does not happen again! Hope everyone can find something to enjoy in this change-of-pace video, even if you have to fast forward through most of it.

[@Reman1975]

It's probably not people moaning for the sake of moaning, or trying to be malicious. Back in the day, the "Natural" rubbers used on cars DID react with oils. I've seen door seals on a 70's ford that had turned to a swollen sticky mess because the owner used to grease them up yearly to prevent the seals from freezing the door shut in winter. So I think the real reason for all the comments was probably because of "Common knowledge" (that is now outdated) still being passed down to the younger generation.

[@skunkjobb]

It depends on what type of rubber, some are fine with petroleum oils and some are not.

[@PJBonoVox]

This exactly. 99% of the comments on these kind of videos (especially the angry ones) are just basement dwellers who have never turned a wrench in their life. They just parrot things they've heard to try and look knowledgeable.

I’m a mechanic with over 20 years experience, and I can honestly say that I also have NEVER seen any problems with using penetrating fluids to lubricate rubber parts for instillation purposes. I’d much rather risk a minor swelling over years than a damaged part that has to be specially ordered. That being said, I usually use synthetic caliper grease to lubricate sticking rubber parts. Love your videos

[@revolutionday1]

In your "over 20 years experience" I'm wondering if you've ever happened to hear of something called....I dunno'...."silicone spray"?

[@petelattimer6808]

@@revolutionday1 i use silicone based spray or grease on all rubber or rubberised parts that need lubricating that might possibly seize over time (like brake caliper sliders) and that (like also some caliper sliders) ANY amount of swelling in the rubbers would be a negative thing. for the record im also a mechanic with almost 30 years experience.

[@BWater-yq3jx]

I think your rule-of-thumb is that if the component is designed to be regularly exposed to oil in the course of normal use, then you can put WD-40 on it. The clear point of differentiation here is NITRILE rubber.

[@anthonypark8569]

I thoroughly enjoyed your presentation and efforts. Its your car, your choices and your money. Who is anyone to say how you should or should not do anything to your car. And stepping back, it's a few small sprays to aid in installation. Come on, anyone that would comment on such a small thing needs to think about their own choices in life that has led to them comment online. Love your channel and your approach.

[@theoddjobs3749]

absolutely brilliant, I was laughing so much at the end, I use WD40 for the same, the cars we work on are 30-40 years old so the old rubber has perished massively, Its very minimal what WD40 will do when you factor in heat/oil/fuel/weather, great videos :) keep them coming, 👍🏻 love the channel :)

[@arnoldcp11]

Great video 👍 thanks for the experiment. As others have said, in the past (and on those EPDM vaccum hoses) this may have mattered due to the rubber chemistry. But modern materials like nitrile, viton, and PVC, its pretty much a moot point. Also, I noticed you missed a spot with the WD-40. Make sure you go back with a second gallon or else there could be big problems.

When working on an old engine I soak the engine bay in WD-40. It seems to soften plastic, rubber and wiring. It also softens old grease and grime and makes it come off easier later on. The biggest problem with o-rings and grommets is where they're being made these days overseas, they just aren't to same level of quality that they once were.

[@TradeWorks_Construction]

That’s some really interesting results because my personal experience with O-Rings for pressure Washer hoses (European style) have resulted in the O-Rings swelling and quickly deteriorating if sprayed to help lubricate when tightening the hose into the pressure washer and wand. After destroying all the O-Rings before even a single season was up i switched to silicone grease which gave mixed results (some O-Rings did fine others not so much). Eventually I switched to NYOGEL 760G a silica thickened synthetic hydrocarbon grease which i purchased for 12v DC automotive wiring as silicone grease hardens over time. While this stuff is pretty pricey $22 (Feb 2024) for 50g/ 1.75oz tube, a small amount goes a long ways. What makes it worth it for me is it’s now my single go to choice for ALL my electrical(Residential & Automotive) and plumbing (O-ring + valve sealing/lubricating) needs. For those only familiar with quick disconnect couplers wondering why I was needing to lubricate my pressure washer hose connection o-rings, the M22 Euro use a very different method for connecting that requires tightening onto a thread, not very fast but a preferred choice for hot water and eliminating leaks.

[@CopperMurdoch]

I learnt something. Thanks!

[@flamingjoey]

I restore cars for a living, we use WD-40 ALL THE TIME specifically for shining up old rubber grommets and hoses that we need to re-use. It really helps bring back they’re luster and makes them nice and black again. I honestly never thought about it deteriorating them, but it’s good to know it’s alright, thanks

[@rajZ772]

Hey there, is used WD-40 on the gaps of front weindheld as i saw some rust in there and then i wiped it with cotton buds. But some WD surely will be staying there into the gaps after spraying . Will that harm the windshield silicone? And will that cause water leakage ino the car?

[@eliefrancis9356]

Is it a problem if I put the small rubber before the filter cartridge then the cartridge? Knowing that it should have been place on the outside of it? Will it cause a problem or I can wait till the next oil change?

[@artyboy92]

Very interesting experiment and the results are pretty much as expected. My personal choice for installing seals/gaskets/orings is rubber grease because excess can be wiped off with a rag with no solvents/cleaners and any inside the engine will dissolve in oil. Silicone spray is definitely my choice for door seals and exhaust hangers however.

[@TheBrokenLife]

I like silicone spray for just about everything these days just because it works awesome. A little Windex on a rag tags the excess off fine for me. I don't normally worry about it too much.

[@TransAmMazing]

Yeah, I’m still gonna use WD-40

[@TacticalBaconPatches]

Don't forget the classic option of spitting on it, a solid choice of lubricant for installing tight coolant and vacuum hoses on pipes.

[@tomitstube]

nice job, as you went thru each step i kept coming up with, "what about heat changes..." "what about longevity..." "what about... very thorough test with convincing results and analysis. the ending was hilarious.

[@PowderMill]

Thank you! We have been using Silicone Spray Lubricant (mostly WD-40 brand due to the lower cost) for most of the rubber and other compositions of seals and moldings in our ambulances, Fire apparatus and rescue vehicles now for over 3 years. The pliability and longevity SEEMS to be significantly better than the days when we used to use WD-40 (the “original” WD-40 kerosene type product). If you think rubber seals and hoses used in more consumer type items / in vehicles / etc… and other products are expensive…. When we have to order replacements for our fleet of emergency vehicles, IF the parts are still available, the costs are usually astronomical. Preventing rotting of materials with such an inexpensive and easy way…. It’s a no brainer.

[@ulrich_badmecanique]

I sometimes spray a little bit of wd40 on old worn out weather stripping and exterior seals.... I am unsure where I got that idea from but its something we do here. It cleans it really well, tends to make it shine, feels softer and newer to the touch, and best of all, protects it like a wax and makes sure moss and stuff doesnt grow again for a while. I've done it on my 22yo daily when I got it over a year ago and haven't seen any change since, the car spends 99% of its time outside. If you don't use too much I don't see any issues really.

There was some color change on soaked test set, so there could be tiny amount of rubber material that got released, or it could be from the film canister or manufacturing process of rubber. Could it be that nitrile rubber compound has evolved and fine tuned over time and it was earlier mixes that did get harmed by wd-40, or simply wd chancing their mix over time to fit new safety standards and maybe they did notice such effect and modified the mix in secret, cause if that was the case it would been huge blow to brand. It well as be that rubber parts being ruined were never nitrile rubber but other compounds that do get damaged. I dont think this experiment proves with out the doubt that wd wont eat rubber part, only that it wont eat modern nitrile parts. Other mixes of plastic and rubber are still in question. Still thank you for doing the test!

May I add, typical o-rings and grommets benefit by using dielectric grease or "tune up grease" typically used for spark plugs and such. Its almost clear, very slight white thick silicone based grease. It will not harm rubber products with long term exposure. Amoung others, it was tested over 20 years on a hot tub filter O-ring 1/4" x 8" in Dia. without expansion over term.

Sir, I am truly impressed by the level of detail and accuracy in your video content. Thank you from the bottom of my heart for your efforts. I wanted to share how your video has been particularly helpful to me. I live in India, and I've noticed that products I receive from the USA, such as shoes or laptops, often have issues with rubber parts drying out and deteriorating. This happened to the laptop my uncle sent me from the USA. I was unsure if using WD-40 would be a good solution to preserve the rubber. After watching your video, I decided to spray WD-40 on my laptop to prevent the rubber from becoming sticky due to the excessive heat here in India. The rubber now looks much better, and I hope that treating it with WD-40 will extend the lifespan of my laptop’s body. Thank you once again for your valuable advice.
