From my fiancé,
[cleaning stuff: rags with solvent, oil, grease, gun powder, ect]by the way, I'm on the 3rd time through the washer for your cleaning stuff and it still stinks. Might be a lost cause.
See if they have any suggestions on the forums. Or a section for poor wives who have to clean up their husbands' greasy messes in order to be supportive of their hobbies.
