This is quoted from Mary Hart of Everyday Cheapskate:
"I had a similar problem, and tried for at least 15 years to get rid of it. Nothing worked, including mayonnaise and several other homespun ideas. Then a painter who specializes in antique restorations suggested that I try JASCO Furniture White Ring Remover (about $5).

As of this writing, it is on sale at www.paintplus.com for $3.75 plus shipping and handling." ... View related article.
