Default Will WD-40 Harm Rubber?

Looking for a lube to help remove the stabbers from the rubber c6 muffler hangers when I change out the catback to an NPP.

spraying is ok on rubber, soaking is NOT ok.

WD-40 contains mineral spirits which will evaporate, but soaking will cause swelling and other damage.

generally folks just avoid WD-40 on rubber just to be safe.

I'd say don't use it till you get a reply from someone who knows. I have been told that wd40 is kerosine. I also have been told that kerosine is bad for rubber. Maybe google?

Yes. I posted same time. What I heard is twenty years ago. If I sounded like I'm not sure, it's because I'm not. I was just warning not to do it till someone knowledgable replies.

ok. my reply was based upon a actual phone call made to WD-40 folks themselves.

the shortened version of their answer was..
soaking rubber or rubber bushings in WD-40 would cause swelling. they did not recommend soaking. spraying will not affect the rubber what so ever.

generally the thought is just dont and be safe

Petroleum jelly works great for this. It also keeps them quiet.

I used WD-40 on my exhaust rubber hanger "hooties" when I switched out my exhaust. No issues and it's been over a year.

WD-40 works great taking the hardened rubber off of your rear 1/4 panel from doing burnouts at the track. Spray and wipe off with a paper towel. No harm to the paint. Kind of off the subject but maybe not......
