when nothing else is around use 90 weight gear oil and apply it lightly then wring it out and all through the filter.You could also get some air filter oil from a lawn mower shop as most commercial briggs and Kohler motors use oiled foam pre-cleaners and their filter oil is made by Bel-Ray.
any foam filter oil will do. Any motorcycle shop will have it in abundance! I personally like No-toil brand oil and cleaner, seems to be the easiest I ever used on motocross bikes which are cleaned about once or twice a week.
