Turpentine is an excellent cleaner for paint brushes. If youâve wondered how to clean your brushes effectively, this oil-based solvent will do the job for you. Most cleaning spirits can only dissolve fresh paint. However, turps goes a step further as it is able to clear slightly hardened paint from brushes.
Best Answer: I just started using Ammonia + Water (warm even better) and it works great removing old or hard to clean paint from brushes and other art materials. Ammonia is stronger than soap so with less you do more; just use a cap of ammonia, add some water, let the brush soak overnight and then rinse it.inse and dry with the bristles pointing up. When you use oil paints first use turpentine to remove the majority of the paint. It's not the most glamorous part of painting but it has to be done right away before the paint starts to set in and ruins your brushes.
