Velcro is one of those cool inventions for clothing and other items to save money and time. Unfortunately, Velcro has a tendency to lose its stickiness after a while like stickers. Since Velcro does not have a residue that can wear off, dirt and build-up often stops Velcro from working. A small-tooth comb can remove dirt and fabric build-up to get Velcro working again.
Pull out dirt and lint on each side of the Velcro with your fingers. Using your index finger and thumb, pull out dirt and fabric caught in between the fibres of the Velcro.
Comb out remaining build-up in the Velcro with a small-tooth comb, which is a useful tool for lifting and removing tiny particles embedded in the Velcro.
Remove dirt and lint from the small-tooth comb and discard.
Repeat steps 2 and 3 until all or most of the traces of dirt are free from the Velcro.
Stick the two pieces of Velcro together to stick.
Wash the small-tooth comb after discarding the dirt, then dry.
Search the Velcro for any tears. If you notice tears or if the Velcro is coming apart, it may need to be replaced.
