To store used paint brushes properly, you need to clean them thoroughly and then store them in a way that maintains their shape and prevents them from drying out.
Here's a breakdown of how to clean and store your brushes:
Cleaning Paint Brushes
- Remove Excess Paint: Wipe off as much paint as possible onto newspaper or a rag.
- Choose the Right Cleaner:
- Water-Based Paints (Latex, Acrylic): Use warm water and soap (dish soap works well).
- Oil-Based Paints (Alkyd): Use mineral spirits or paint thinner. Always follow the manufacturer's safety instructions when using solvents.
- Clean Thoroughly:
- Water-Based: Rinse the brush under warm water, working the bristles with your fingers to remove all traces of paint. Repeat until the water runs clear. Then, wash with soap and water, rinsing again until clean.
- Oil-Based: Dip the brush into a container of mineral spirits, working the solvent into the bristles. Wipe the brush on a rag to remove the paint-laden solvent. Repeat with fresh mineral spirits until the brush is clean. Wash with soap and water after cleaning with solvent to remove any remaining solvent residue.
- Remove Excess Water/Solvent: Shake out excess liquid and gently blot the brush with a clean rag.
Storing Paint Brushes
There are several methods to store your cleaned brushes:
- Hanging: The ideal way to store brushes is to hang them vertically with the bristles pointing down. This prevents the bristles from bending or deforming over time. Use a nail or hook.
- Original Packaging: If you still have the original packaging, storing the brush back in that protective casing can help maintain its shape.
- Wrapped in Paper: Wrap the brush head in wax paper or parchment paper and secure it with a rubber band or tape. This will help keep the bristles straight and prevent them from drying out in an odd shape.
- Horizontal Storage: If you must store brushes horizontally, lay them flat on a surface, making sure the bristles are not bent or compressed.
Important Considerations:
- Avoid Storing Wet Brushes: Always ensure brushes are thoroughly cleaned and mostly dry before storing them. Trapped moisture can lead to mold or mildew.
- Solvent Disposal: Dispose of used mineral spirits or paint thinner properly according to local regulations. Do not pour them down the drain! Let the paint solids settle, pour off the clear solvent for reuse, and dispose of the sludge at a hazardous waste disposal site.
- Brush Keeper: For short periods (e.g., overnight), you can wrap a brush tightly in plastic wrap to keep it moist. However, this is not a long-term storage solution.
By properly cleaning and storing your paint brushes, you can extend their lifespan and maintain their performance.
