I have found a name brand product that is worth every penny!!! Mr. Clean Magic Eraser(Extra Power) lives up to any/all expectations. My art room tables are probably 20 yrs old(I've used them for 8 yrs..but a teacher told me they had been here since the school opened!). I'm not sure if my students are extra messy this year...or the tables are just beginning to show their age......BUT I HAD TO DO SOMETHING!! I like my room to be nice & clean...and my terrible looking tables were starting to throw off my groove! I picked up a 4 pack of Mr. Clean Magic Erasers at CVS & thought they would be worth a try(they were on sale!). The first thing I did when I got to school this morning was try them out! WOW!!!!!!!!!!!!!!! It was such a drastic difference from my normal cleaning supplies. I am totally sold!!!! I might not use them every day.....but a once a week cleaning will keep my tables looking half their age(if not better!). TRY IT OUT FOR YOURSELF!!! You won't be disappointed!
