Don't use petrol, it breaks down the foam!
I've got 20+ year old NSR foam filters that have been pretty much constantly in contact with standoff and petrol vapour, and they are as good as new. I think someone's scaremongering... probably a company trying to sell over-priced cleaning agents!
We would always clean the foam filters in the chainsaws and pertol disc cutters with a petrol/2T mix (which in high season could be 2 or 3 times a day) when I was a service engineer in the hire trade, and it never caused the elements to break down. That was some serious cleaning too, to get the concrete dust out of them!
Cool, must be the crappy quality of the filters I buy! I've just been told bad things about petrol opening the foam etc. Good to hear an alternate experience. I usually use metho and hot soapy water, gets my dirt bike ones shiny and clean again. Sealing the buggers against dust is another matter altogether! So nice not to have to worry too much about that problem with road bikes.
