And I use them for cleaning my cutting mats - use a pushing motion in both directions and a lot of lint, etc will come out of the cutting grooves - can be used on a wet or dry mat. The ones with the little sharp points on the sides are great for getting gooey gunk from around the sides of the sink, etc also without scratching. Can't think of more right now, but I use them a lot! Thanks for the tip about electric cords!
