OHMYGAWD!!!! My teenaged daughter got permanant black magic marker all over the leather seat of my husband's Mercedes! I figured that she would be grounded for the rest of her natural life. I looked online and saw several references to Mr.Clean Magic Eraser and figured, what the hell... And it worked!!!!!! On beige leather! I had to put some muscle in it but I couldn't believe it! It looks like a sponge and you wet it, squeeze it out and scrub. The sponge seems to deteriorate over time (USED ONE WHOLE SPONGE FOR THE STAIN)but is well worth the $3.00. After that...I felt powerful and went after some ink stains on my pocketbook. This thing is great!!
