WD-40 expanded my carb boot

[savage24x]

I let my carb boot soak in WD-40 with the rest of the carb and today... I picked it out... It's huge. What do I do?

Leave it in the sun to dry.....or buy another.

You're not supposed to immerse rubber products in it. This was taken from ADV rider;

"Thank you for contacting the WD-40 Company concerning the use of our product. WD-40 contains cleaning solutions, and for this reason we do not recommend using WD-40 first and then applying another lubricant.

WD-40 can swell rubber or buna rubber gaskets when the gasket is immersed in the fluid. If the fluid is sprayed on and wiped off, the gasket will not swell. This swelling will not ruin the gasket, however it will swell the rubber. We use buna gaskets in every single can of WD-40 aerosol. We build the valves in our cans with this swelling in mind. After swelling the gasket retains its integrity.

Thank you again for contacting the WD-40 Company. Please let us know if we may be of further assistance.

Best regards,
Eva Zabowski
WD-40 Customer Service"

This is why I quit using WD-40 as AFO in my traxxas rigs when I first started in the hobby. I do not know why Traxxas recommends it.

Hah I always learn the hard way. Thanks guys. I let it soak in Nitro fuel because that's the first thing I thought of that never gave me an issue and it's working so far.

Sorry you were the sacrificial goat but man, that's great information to share.
I had no idea WD-40 did that.

Other cans of penetrant/oil do the same thing, but on the other hand if you use it to just wipe off your rubber pieces it will keep any dry rot from occuring
