Put the stock in the dishwasher and tell us how it works out. No Im not kidding, I read about it on surplusrifle.com, dont tell the wife if you plan on doing it. Always better to ask forgiveness instead of permission.
The dishwasher does work very well. use regular dishwashing soap but on
pot scruber leve in all night to dry. I do this all the time it works
very well. And it will not hurt the dishwasher or the stock.
Wife should not mind. It is OK.
I used brake parts cleaner on metal parts.......it worked pretty good
