Can you pour acetone down the toilet?

The short answer is no, and for very good reasons. As acetone is a powerful solvent, it may seem logical to use it to unclog a blocked drain or plughole, and it would be an easy way to get rid of your waste acetone. However, while it will probably dissolve whatever is blocking your drain, it probably won't stop there.
