There are several different grades of Scotch Brite. The baby blue 
grade, which is the gentlest, might be preferable to the green, red, 
gray or other grades. That's all I remember of the grades but if you 
find a box of the stuff, the grades should be described on it. Perhaps 
the info is also on the 3M website somewhere?
