Homemade Nut Loosener

Free up rusted parts with this unusual concoction

Family Handyman

Rusted bolts and nuts can be stubborn as all get out to loosen. I make my own rust penetrant by mixing half automatic transmission fluid and half acetone in a metal oilcan. The solution really penetrates—after a few minutes, even the toughest bolts and nuts spin loose (with a little elbow grease, that is). Best yet, it’s stuff I already have on the garage shelf. — Calvin Stevens
