how to clean dried paint brush
Step 2 - Rinse Your Brush. Having purged your paint brush of wet paint, you're ready to rid it of any caked-on dry paint as well. If the dried paint is oil-based, begin this step by pouring turpentine onto the stained bristles. Alternatively, if the dried paint is water-based, you'll need to rinse your brush beneath a faucet. When using a faucet to rinse the brush, make sure the water temperature is lukewarm. If the water is too hot, some of your brush's bristles are liable to fall off.
