Believe it or not, this Guide is going to pretty darn small, but the advice will blow your mind!  You know those little marks that porcelain, pottery and/or ceramics get when they rub up against something??  Marring an otherwise beautiful piece??  Well, the solution is here and believe it or not,  I learned it off Antiques Roadshow (British version).  You take one of those gum erasers (mine's white & oblong and really works crappy for erasing pen, pencil or even gum....LOL) & apply a little spit (yes, that's what they said on the show and I about fell over laughing) and rub and viola!  It's clean!  This advice is a godsend and right up there with learning about Goo Gone products.  Happy Cleaning!  Oh, and remember to vote this guide as helpful if you've been helped. :o)
