The provided reference states that dried art paint (likely acrylic) on brushes can be removed by soaking the brush, allowing the dried paint to loosen and then fall away from the bristles.
While the excerpt lacks specifics, here's a more detailed approach based on common practices for cleaning dried paintbrushes:
Steps for Cleaning Dried Paint Brushes:
-
Soak the Brush: Submerge the brush head in warm (not hot) water. The temperature is important as hot water can damage some brush bristles. Let it soak for a considerable time – several hours or even overnight – to soften the dried paint. You might consider adding a small amount of dish soap or brush cleaner to the water to help break down the paint.
-
Gently Loosen the Paint: After soaking, try gently loosening the paint with your fingers. Avoid pulling or yanking on the bristles, as this can damage them. A brush comb or a specialized brush cleaning tool can also be helpful in this step.
-
Rinse Thoroughly: Rinse the brush thoroughly under running warm water, working the bristles to remove any remaining paint residue.
-
Repeat if Necessary: If the paint is particularly stubborn, repeat steps 1-3. You might need to soak the brush for a longer period or use a stronger solvent (appropriate for the type of paint used, see cautions below).
-
Shape and Dry: Once the brush is clean, gently reshape the bristles with your fingers. Lay the brush flat or hang it upside down to dry. This prevents water from running into the ferrule (the metal part that holds the bristles) and loosening the glue that holds the bristles in place.
Important Considerations:
-
Type of Paint: The cleaning method depends on the type of paint used.
- Acrylic paint: Water and gentle scrubbing are usually sufficient.
- Oil paint: Requires solvents like turpentine or mineral spirits for initial cleaning, followed by soap and water. Always work in a well-ventilated area when using solvents.
- Watercolor paint: Generally washes out easily with water.
-
Solvent Safety: When using solvents, follow the manufacturer's safety instructions carefully. Wear gloves and eye protection, and work in a well-ventilated area. Dispose of used solvents properly.
-
Bristle Type: Natural bristles may require different cleaning techniques than synthetic bristles. Some delicate natural bristle brushes should only be cleaned with specialized brush cleaners.
Cautions:
- Avoid using harsh chemicals like paint thinner or acetone, as they can damage the bristles and the handle of the brush.
- Never boil the brush or use excessive force when removing dried paint.
The goal is to dissolve or soften the dried paint so that it can be gently removed without damaging the brush. The key is patience and using the correct cleaning method for the type of paint involved.
