Pull apart the two pieces of Velcro and put them on a table. Notice that one section is soft and the other is rather hard and spiky. This is how Velcro achieves the “hook-and-fastener” technology that makes the straps stick together.
Carefully pick out any visible hair, fuzz, string, lint and other debris from both sections with your fingers. If some particles remain trapped, use toothpicks or tweezers to remove them.
Roll up a piece of masking tape several times over and use it to remove any remaining debris from the softer section of Velcro. Repeat the dab-and-lift procedure with packing tape for stubborn debris.
Comb debris from the hard section of Velcro with your choice of household tools, but start with a teasing comb. The comb is ideal because one side is a fine-toothed comb and the other is a wider-tooth comb, and both sides work well to remove debris from the hard, sticky section of Velcro. If you don’t have a teasing comb, try a small lint brush or small wire brush instead.
Wash the two Velcro sections in warm, sudsy water and let them air dry.
Spray the Velcro sections with anti-static spray, which will help repel dirt and debris from accumulating and reducing the staying power of the Velcro straps.
