Is there some kind of conspiracy against silicone lubricants?

I DON'T EVEN HAVE TO SHARPEN MY KNIVES!

I just spray them with silicone spray and they run through tomatoes like a hot knife through butter.

OMG WHERE IS MY THUMB!? AND WHY IS THERE ACTUAL BLOOD COMING OUT OF THIS BLOOD ORANGE!?

I think I've used isopropyl

If it were that easy to clean off, silicon grease wouldn't be banned in some laboratories.

Any cleaning instructions involve hot water, solvents and/or soap, and lots of scrubbing. And I bet not all of the grease is actually removed.

The best silicone grease I've used is Honda's Shin-Etsu grease. Works great on door seals, window tracks, and other rubber parts. You can get it on Amazon for about $16, or a little cheaper at some other sites online.

OP I think the real answer is that silicone grease is expensive, and regular ole' petroleum/synthetic grease works fine for 1/10 the cost. I've never seen any damage to either bushings or o-rings caused by standard grease. I'm no chemist, but even if there are negative effects on a molecular level practically speaking petroleum grease is harmless to suspension bushings.

My wife bought some silicone based lube, but we preferred the water based ones.

... Wait... This isn't the Love and Relationships forum.

*backs out of thread*

:whiste: The garage is no place for this sort of humor. This is serious business.

Please give yourself 20 infraction points right now or ban yourself for a week. :colbert:

To all: take this advice at your own risk. Certain types of rubbers are widely known to suffer negative effects when in contact with oil or petroleum greases.

It's one of those things that makes no sense. Rubber bushings and seals are damaged by petroleum based grease, and the proper lubricants to use are silicone based.

False. The synthetic rubber compounds used in vehicles has been petroleum grease stable for decades. In many cases you don't want synthetic greases for two reasons.

1) They can't burn or melt off areas they aren't supposed to be in or on.

2) They won't dissolve away in gasoline so a sludge can build up.

But go to any auto parts store and try to find silicone grease. Ask your mechanic-- I bet he won't even know what silicone grease is.
Some companies do sell silicone grease, but they don't label it that way. They label it as "bushing grease" and "synthetic grease" and things like that and don't even mention silicone on the label. You really have no way of knowing whether they really are silicone.

If you want silicone grease to install some bushings right now, and can't wait for a delivery, your only option is to go to Ace Hardware and buy plumber's grease.

You can get either a lower viscosity dielectric grease or a higher viscosity brake grease that's silicone based, but I would still avoid anything that doesn't tell you what it is on the label.

None of the vehicle rubbers likely to come in contact with petroleum oil or grease suffer negative effects within a "reasonable" # of years if ever. It has been this way for decades.

If on the other hand there is a leak and oil is spraying everywhere because it's under pressure, who knows where it may end up, and yet I don't recall ever hearing of a case where a spraying oil leak directly caused the failure of another part due to rubber degradation.
