They put grit in the plastic on those brushes so be careful!

Yeah, still not rounding off the piston. Been using this method for quite some time now. Nothing rounded one little bit. Use it on a low speed. I think if I can run the brush on my skin the metal piston won't mind.

Metal polish + QTip = DIALED!

Only work on the top of the piston. Spray with brake clean, dip in fuel, reassemble.

Wow I woulda never thought of the toothpaste but I'm gonna test it. Depending on when kids fall asleep either tonight or tommorow. In the past I've let after run soak on top and rub in circular motion with my finger. I like this new method though its less wear on my trigger finger. Thanks again

The crest white works best and the blue colored cool mint is o.k.

your best bet would be to try some simple green and scoth brite pad like dude said, also like other guy said watch how hard to scrub, the metals are kinda soft and if you round off the seal then might as well buy a new one, i mean there cheap compared to a new motor right?, save yourself some time. and unless its really built up where your finger nail can catch an edge in the blackness, dont worry bout it i mean pull your plug out of a car, lawnmower, look at that piston, same deal man. hope it helps
