Rinsing And Drying
Rinse the brush thoroughly with warm water to remove any remaining cleaner. Use your fingers to gently work through the bristles. This helps dislodge any trapped residue.
After rinsing, shake the brush to remove excess water. Use a clean towel to blot the brush dry. Avoid twisting or pulling the bristles as this can damage them.
Lay the brush flat on a clean surface. Ensure it dries completely before storing. This prevents mildew and keeps the bristles in good shape.

Always reshape the bristles after cleaning. Lay the brush flat or hang it with the bristles pointing down to dry. This prevents water from seeping into the handle.
Replacement Tips
Even with the best care, brushes wear out over time. Knowing when to replace them is key.
Inspect your brushes regularly. Look for signs of wear and tear. Frayed or stiff bristles indicate it’s time for a new brush.
