How to Clean Paint Thinner
- 1). Place the container of paint thinner in a safe place after you finish cleaning your paintbrushes. Place it out of reach of pets and children, and where it will not get knocked over. Let the paint thinner sit for a few days, this will allow for the particles in the paint thinner to settle to the bottom of the container.
- 2). Place a funnel in the top of the paint thinner's original container. Pour the paint thinner slowly into the funnel, so the sediment on the bottom does not get mixed up, until the sediment in the bottom is left in the container. Place a coffee filter into the funnel and slowly pour the rest of the paint thinner and sediment into the filter. Let it sit while the paint thinner drains through the filter.
- 3). Replace the cover to the original paint thinner container. Wipe out the container used to clean the brushes with a paper towel. Let the filter and the paper towel dry, and then dispose of the filter and paper towel.
