I was referring to the Z-Tuff product as being great. I would never try to use a magic eraser by itself with just water on leather or vinyl. The Z-tuff cleaner actually comes with a "melamine sponge" which is basically a magic eraser. http://www.defender.com/product3.jsp?path=-1|10918|2303331|2303335&id=1785472I have used it on my boat seats on occasion too (when careless mechanics left a mess) - but it is actually not recommended for use on vinyl and continual, repeated use can eventually damage a surface. Just a warning to those who may not know how it actually works.
