I mixed them up with other 3M sanding pads I bought a few years ago that can be washed and reused many times. They're great, maybe 4-5 minutes and then practically useless. I washed them out to continue using them but they don't have the durability and quality of the earlier 3M abrasive pads. "Unfortunately I bought 3 boxes of 3 different grits so I'll stick with barely mediocre sponges but it doesn't have to be if you follow my advice. Very disappointed especially I thought I was getting a quality product that works so well from the same company.
