Cleaning Chalk Paint Brushes

Below are the steps involved in cleaning recently used chalk paint brushes where the paint is still relatively wet:

  • Start by squeezing out as much excess paint as possible out of the brush.
  • Put the brush under a flow of warm water whilst gently squeezing the bristles to remove as much paint as you can.
  • When you’ve got rid of all the paint, use mild soap to clean the chalk paintbrush using your fingers. 
  • Rinse your brush with warm water to remove any water-based paints and excess wax.
  • Be sure to repeat these steps if you find that there’s still paint left in the bristles. 
  • Once you’re done, make the loose bristles straight and flat and wrap them in a paper towel or lint-free cloth to soak up any excess water.
  • This will help to speed up the drying time whilst also ensuring that the brush keeps its original shape. 
  • You can then set your brush on a flat surface and leave it t dry for a while. 
  • Alternatively, you may want to set your bristles facing downward so that the moisture from the wet brush drops down to air dry more quickly. This can be done with synthetic bristles and natural wax brushes.

You could also choose another chalk paint cleaning method that involves white vinegar.

  • Combine warm water a white vinegar in a small container.
  • Mix the two together and dip your brush into the solution.
  • Leave it to soak up the solution for around half an hour. 
  • You can then use your fingers to squeeze the bristles to remove the solution, along with any chalk paints. 
  • You can then rinse the brush with warm water and gently wrap it in a paper towel to dry. 
  • Once the bristle end has dried for a few hours, you can start painting to see if it’s ready to use.
