Chainsaw Repair

FWIW you can use easy off oven cleaner and get about the same results . A word of caution do not get impatient and use a flap wheel on a cylinder .You'll grind right through the plating faster than you can say Jack  Robinson.Been there ,done that .

I might also add that 3M abrasives like the green pads are less agressive than sandpapers .Unless you really lay the elbow grease to them they will only take out the tramp aluminum .Wear some kind of rubber gloves weather you use oven cleaner or muratic acid and have plenty of ventilation else the fumes will get you .Not good .
