Depending on the type of paint used, the brushes and rollers used for painting will have a different maintenance.
When using water-based paints, you can clean the brushes by letting them soak in water and then rinsing and drying them so that they do not rust.
If we use solvent-based paints (turpentine, or nitro), the same solvent used to dilute the paint must be used for cleaning.
