Cleaning brushes used with oil paints or varnishes can be a chore, and if not done meticulously it can ruin them due to lumps of dry paint that would settle between the bristles. Also, a large amount of solvent may be required during the process. An easy and inexpensive remedy for cleaning them is precisely the subject of this article.

Advice
- If you intend to reuse the brush within a short time (for example in the 48 hours after washing), put a few drops of solvent in a plastic bag without holes, and close it around the bristles of the brush, securing it with an elastic, so as to obtain an airtight seal. Remove as much air from the bag as possible.
- To clean brushes used with solvent-based paints use only the first of the two methods presented. Use separate jars for thinner products.
