Latex paints are easy to remove from paint rollers simply by using soap and water. Dried latex paint that comes off with a paint scraper can be disposed of with your household garbage.
- Fill two 3.8 L buckets with warm water. You’ll use one bucket for washing the roller and the other for rinsing.
- Add 1 tablespoon of dishwashing liquid to the washing bucket.
- Remove as much excess paint from the roller as possible by running the roller over the wall in an inconspicuous area or by running the roller over several layers of newspaper. If paint has dried, then remove the dried paint with a paint scraper.
- Remove the roller from the roller tube and dip the roller into the washing bucket. Use your hand to scrub the roller while it is submerged in the soapy water.
- Place the washed roller into the rinsing bucket and rinse it until it is clean. Alternatively, you can use a garden hose to rinse any remaining residue from the roller.
- Wrap the roller in a clean towel to remove excess water. Place the roller in a well-ventilated area to dry and try to let it hang while it dried to avoid indenting the brush.
- Store the roller after it has dried completely
Method 2 of 2: Remove Oil-Based Paint
Oil-based paints will not wash away with just soap and water. Rinsing them in water can cause the fibers to become brittle and unsuitable for reuse.
Make sure to wear gloves when you work with paint thinner. Goggles will also prevent the material from splashing into your eyes.
- Fill a 18.9 L bucket about 50mm to 75mm full of paint thinner.
- Remove your paint roller from the roller tube and place it in the paint thinner.
- Roll the roller in the paint thinner and then squeeze the roller over the bucket using your hands.
- Continue dipping the roller into the paint thinner and squeezing it until the squeezed-out paint thinner runs clear into the bucket.
- Shake out the excess paint thinner and place the roller back on the roller tube.
- Spin the roller on the tube until the roller fibers are only barely damp.
Since paint thinner may fly off of the roller during this process, using goggles during this step is a good idea.
- Remove the roller and store it in a plastic bag, such as a bag used to wrap bread.
- Pour your used paint thinner through a funnel into its original container and recycle it for another use. If you don’t want to recycle your paint thinner, then you will need to dispose of it according to the regulations in your local council.
