dude I soaked mine in Simple Green for a week straight, really in 1 or 2 days was enough, but I took them out, shit slid right off. Get a toothbrush to scrub excess off.

Get new ones and they will be clean! :biglaugh:

Are these stock? Just curious as to why you would want to do that.

I had new ones but they were all size 1's when I ordered them.

Im cleaning the stockers up for my GE since it ran on cheap 87 its whole life.

Im gonna use the stock size rings, But the play on the new pistons was massive. I was unaware there were different sizes when I bought them, so I just ordered a STD size set.

Im gonna use the rings from the new pistons on my old pistons. The rings are all the same size BTW.

I think Im gonna use simple green and some elbow grease. I can swing by wal mart and get the concentrated stuff and I have 2 days before my bearings show up to let them soak.

By play you mean the ring end gap? You must check your ring end gap in the bore with a feeler gauge and file it to the correct size needed.
I'm sure you already know this, but i'm just checking.
When you take your block to the machine shop to be honed, (required for the rings to seat) don't forget to take the pistons you intend to use. When the machine shop in checking your bore for out of round/taper, they can measure the pistons for clearance.

Already honed and dglazed it myself, The rigs are fine, its just that the pisons were way under sized. i could put them in the cylinder with no rings and move them back and forth with about a dimes width of clearance on the walls. :icon_conf

Hey what you need to do as well as everyone else here is if you are cleanning parts like that? boil them in ANTFREEZE.... doit outside and be very careful it will clean anything thats stuc to it and will not harm anything plus it gets deep in the cracks i do this to my R/C engines and they come out like new. i have 1000.00 R/C planes and the engines have NOT failed me.....you should try it...... this is a fact if any of you have had a BHG when you pulled the head you can tell where the BHG happend because of the pistons will be NICE and CLEAN...... try it
