Make Old Hard Rubber Soft Again

bapmia · Jan 12, 2014

I wanted to share a easy method I recently used for restoring 1 of the hardened rubber intake hoses/ducts on my FJ62. These hoses, every bit many of you know, harden and crevice over time. On my truck, the hose that attaches to the throttle body was badly croaky, so I replaced it with a new one courtesy of beno (even with his generous discount, the toll is ridiculous for what information technology is). Still, the other hose (the i that attaches to the MAF), is NLA. Mine was in perfect shape with no cracks, but it was hard equally a rock. It was only a matter of fourth dimension before it failed.

So, I started doing some research on whether it was possible to re-soften hardened rubber. It turns out an onetime trick is to boil the hardened rubber office in a mixture of h2o and natural wintergreen oil. I'll spare y'all the chemic caption, only plainly at that place is a chemical compound (methyl salicylate) found in wintergreen oil that restores the elastomeric properties of safety. When y'all eddy the hardened rubber part, the rubber opens up so to speak, absorbs the compound and re-softens.

After reading reports of success all over the internet, I decided to give it try. I bought 8 oz. of wintergreen oil on ebay for $11.00. I filled a large pasta pot with h2o, poured half of the bottle in, and brought information technology up to a gentle eddy. I then tied the hose to a bbq skewer that I placed over the top of the pot so that the hose would hang in the h2o rather than rest on the lesser of the pot (I wasn't sure if this footstep was necessary, just I was concerned that the hose might cook if it sat on the bottom of the pan). Plough on your exhaust fan unless you want the whole firm to aroma like wintergreen chewing gum/tobacco.

Later on 45 minutes at a gentle simmer, I took the hose out and rinsed it in dish soap and water. The results are simply amazing!! The hose is literally similar new--soft and pliable, more than then than the new hose I bought from beno. Full cost $11 plus, as an added bonus, it smells wintergreen fresh. Can't guarantee what the long term results are, just I've read many positive reports on the internet of parts remaining soft for a long time.

Promise this helps.

Hullo, Thank you I'll effort it. Mike

But don't eat it, although it smells good, wintergreen oil volition literally kill you, it's highly toxic.

^^that is kind of adept to know!

Let the states know if the hose is still pliable in 3-6 months. Cheers for describing what you did!

Concluding words of Socrates?

A friend of mine used wintergreen on some carb boots on a 70s Honda, said they were nonetheless expert a year later.
I'd imagine our nether hood is a scrap more of a hostile surroundings though.

I'd be interested in the long term results. Also, I'm surprised your nonetheless alive afterwards your wife found out you were boiling rubber hoses with poison in her pasta pot.

Yous must have watched real genius besides! Lol. I call back it was " In the immortal words of Socrates."

Luckily I'm the melt in the house and so it'due south my pot! She actually commented on how good the firm smelled LOL!

Aspirin is made from the stuff - and so not only will it soften the rubber, but information technology won't become a headache!

Crawly thread cheers for sharing I will unequal attempt this and let everyone know how it works.

Interesting method/process.

Had to get look it up:

30 ml (about i fl oz) of oil of wintergreen is equivalent to 55.vii g of aspirin, or well-nigh 171 adult aspirin tablets (US). This conversion illustrates the dominance and potential toxicity of oil of wintergreen even in minor quantities. Illiteracy may be a common gene in accidental overdoses and ingestions in adults.

s*** now all we have to find is a style to do this with interior vinyl....

cruisermatt

Information technology's could work double duty as air freshener on interior parts

Only a thought would this work on the window felts since they seem to turn rock hard with age and bind upwardly the window drinking glass from sliding smoothly.

Any takers on trying this out.

Occurs to me, will a bottle of ground-up aspirins also work?
