I read somewhere but have not tried it yet - the Mr. Clean eraser works great - takes everything out. I hope this works for you. Let us know. It also cleans up those dirty yucky white outdoor chairs, then you are to put furniture polish on them.
I must buy some Mr. Clean Erasers. Hubby put new spigots in the kitchen and I could not find any in that mess under the kitchen sink! Must put them on my list since he does the shopping. Good luck.
