2. Softens Harden Paintbrushes
You wouldn’t believe how many paintbrushes are thrown out due to hardened bristles when this problem can be easily rectified. If you have paintbrushes you’ve left collecting dust, all you need to do is drop them into a pot of boiling lemon water. Let them soak for fifteen minutes and then rinse them off with soapy water. They’ll be good as new in less than thirty minutes!
