My niece asked a couple of weeks ago about getting a stain out of an old piece of lace... she put a plant on top of it....not expecting the bottom of the pot to leak....well, it did, and she called me....she had been soaking it in just soapy water for a few hours but it didn't do much..so she said! I said I'd ask my "All-Knowing-friends"!!! SO, here I am, again.....HELP????? AND Thank you in ADVANCE....I promise to write it down!!
