Vintage glassware and the Magic Eraser

As most of you who know me already know, I sell things on eBay. Some of the hottest selling items on eBay right now are vintage Pyrex pieces. Pyrexlover.com has an interesting article on cleaning vintage Pyrex with the new Mr Clean Magic Eraser. Seems it works very good in most situations and works equally well on many other vintage pieces. I have some old Jewel Tea I may test it on. If so, I will post the results.
