Dishwasher works great for plastics, anything aluminum or magnesium will tarnish. Although I will say, I convinced a buddy of mine to put some Subaru cylinder heads and pistons in his dishwasher. Came out clean as a whistle lol. Should have taken a picture of that.Lol, I was actually thinking of putting the head of the 660 and 391 in the dishwasher to make em purdy
I am only engaged, so it's still good until she lives here permanently!!
I'm guessing the dishwasher would ruin them somehow, so I have just been reading the forum on de-gunking a chainsaw (I have 9 currently, and they've all gotten a good workout this year)
