unless theyre really grimy from rotten/dirty wood i do nothing. otherwise soak em in old gas (or new gas since theyre practically giving it away these days )
I have one of these (FloTool 10 Quart Drain Container 11837MI: Advance Auto Parts) that I put simple green in, let them soak for five minutes and then wipe off before you put on the grinder, Pallet Pete does something like this too.
I always blow em off with compressed air. If they're nasty, they soak in simple green or oil eaters (whatever is handy).
I use old premix on them. The gas cleans them and when it evaporates it leaves a little oil to prevent rust. And it gets rid of stuff I'd be tempted to ruin my carb with.
Thanks for the replies. You guys do basically what I was thinking. I was thinking about diesel and ATF. I just was not sure if there was a better way. Good idea on the Flotool container thewoodlands, I can put them in there and shake them to help clean. It will also be nice to keep the cleaning solution in.
I usually take the air compressor to the chains before I do a quick soaking (the chains) in the Simple Green.
For the most part ,Simple green and air . If I get one that has gotten really nasty ,I'll soak it in Coleman stove gas ,the after it's dry ( very important ) ,I'll take a cordless drill with a brass wheel to get the mung and rust off . The reason for all that is , I like to inspect the whole chain if I don't know it's condition . Can't do that when it's covered with dirt . It's also easier on the grinder wheels .
I run the saw at about 1/2 throttle and dip bar into a bucket of sand. It cleans off all the gunk and makes the chain super shiny!! Kidding! Rarely are they dirty enough to need cleaned, but I have used bench-top sweeper brush a few times to knock loose grim off of them.
Soak in Old 2 cycle gas about an hour. Then swish around , amazing how much black gunk comes out. Good time to inspect the links too. Had one (RS , that I bought used that was so stretched, no more adjustment , in the garbage can now) cut 10 cord with it, lots of cutter left, but garbage now. "Stretched" is probably the wrong word , worn / loose / sloppy at the pivot points, guessing poor oiling &/or dirty cutting. ( not from me , from the guy I got them from )
