A MUST FOR EVERY HOME!
Have been using for a few years now, having purchased the first five from an appliance parts dealer who had them near their cash register.  They are phenomenal.  I use them to remove any scum from the waterline of my hot tub, on pots and pans and on any other material where I am concerned about scratching the surface.  They are effective in removing crud from a baked casserole dish without harming the enamel surface and they seem to last forever.  Am now down to our last one and thought I would reorder from Amazon. We have sanitized in dishwasher with no harm to pad.  Any residue removed from pans or tub easily washes off.  The biggest surprise from reading the label is that they are not made by 3M (yet).
