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!
