This tip from AT reader Anna at D16 has to be shared. We've seen the one where you boil your painted hardware, but this is the slow-cook method:
1. Get a crockpot (cheap at Goodwill!)
2. Add hardware
3. Cover with water
4. Add 1/4 cup liquid laundry detergent
5. "Cook" on middle setting overnight
In the morning, the layers of paint will just fall off the metal/glass. It's amazing. You might need to use a toothpick/toothbrush for detail work, but the majority of the paint will come right off with no effort at all. I've stripped dozens of hinges (some with so much paint on them the doors would no longer close!!) and other hardware in my Victorian house over the past year, and this method has been a huge timesaver.
Anna of D16 found got this tip from This Old House. (thanks, Anna!)
