REDECKERReal Copper Thread Pot Scrubber - Woven Double Layers for Extra Strength - Gently Remove Even Persistent Dirt Long Lasting, Set of 2 - Copper Scrubbers - Copper Sponge Scrubber

Since this is made of 100% pure copper, it will not damage your instrument strings. I use this regularly to remove rosin from my doublebass strings. I teach orchestra class, and I often use these for students who forget to clean their instruments.

I have been using these for years. Each pad will last for months. Much better value and "scrub-ability" than SOS pads.

They are extremely excellent

If it wasn't such a hassle to return these I would. They are small for the price and not so well made. Sure they are copper and they will do the trick and clean my pans, but would not recommend as poor value.

Honestly, these are crazy expensive, but cheaper stuff is just copper coated and soon crumbles and makes a mess. Copper kills many pathogens and lasts a long time if you keep it fairly dry. I will buy more because it's the only thing to use for cleaning your best pots and pans.

Works incredibly well. Saved my stove, sink, cast iron. Only drawback is how quickly they fall apart.

These are exactly the same as the two dollr ones at the grocery store. After just a week mine lost its beautiful copper color and flattend out. I bought it because i liked the puffy round shape, and thought it would look nice sitting out by my sink. What a waste of money. It does do a good job of scrubbing pots without scratching, but so does the cheap grocery store ones.

Lasts a long time. Works well.
