I use starting fluid (OUTDOORS..) for cleaning that leaves no residue.


I don't know what the different brands may contain (I use straight
ether for starting), but avoid anything that contains acetone.

Pure acetone is great for adhesive prepping, but getting your hands on
pure acetone is not easy. The stuff they sell in cans in hardware
stores is almost always recycled from industrial users, and it usually
contains some oil. It has been the source of many bonding failures by
home boat builders.

Final wash with methyl hydrate or ethanol - or as the previous
poster noted - ether.

BUT some starting fluids ALSO contain an oil to reduce damage from
"wash down" when starting an engine -- -
