Removing years of bad paint decisions from hinges and door knobs. Easy as water, heat, and baking soda. I actually did this in my old bungalow. Really very easy, butr emember, metal gets hot people.... I may or may not have burned myself.
REMOVE RUST.....1c Borax+2c warm water+1Tbsp lemon juice works wonders on rust. Old pots/pans that are rusted, add this solution(paste like) & let sit 15mins. Rinse+just scrub the rust away. Use to remove rust from appliances & virtually anything metal. Old patio furniture:remove rust+paint. If rust is a bit stubborn, leave 2nd coating on another 15-20mins-should lift right off w/scrubbing sponge.
