Another CMS-O brass cleaning car. With Williams F-7 A-unit.
Day 1: ~3.5 hrs with acetone and provided patches, cut up old robe. Followed by 2.5 hrs dry with patches from robe. Should have done this first. Then 1 hr with acetone. Washed patches in ammonia and detergent.
Day 2: ~ 4 hrs with occasional pad changes. It does not seem to be making significant progress as pads are as dirty as those of the prior run. Cleaned very dirty wheels on CMX and F-7. Alcohol is better than acetone. Also acetone dissolves plastic tube on filler syringe. Will use acetone until fluid in car runs out then switch. Run awhile with fast drip of acetone. Dissolved corduroy on patch. Run a dry patch for awhile.
Day 3: ~ 5 hrs Alternate alcohol and dry with occasional pad changes. Still some black on pads but calling it done. Cleaned very dirty wheels on CMX and F-7.
This was first time track had ever been cleaned. Subsequently can do it all in about 2 hrs.
