Hello beekeeper friends. Dave's supposedly 'white' bee suit really needed a cleaning before we made a school presentation. I bought about every stain remover product on the grocery store shelves. Most of them guaranteed to remove certain types of stains. (Apparently none of these manufacturers had bees in their backyards!). Of course, none of them worked. But the Tub and Tile Spray did take out some of the stains. I was determined that this problem would not get the best of me. So, I turned to the Automotive section! There is a product called Super Clean, a liquid spray or pour, that is used to get off bug and tar spots from the autos. Well, bugs, tar, hmmm = propolis? It worked! Any stains that were left from the laundry aisle cleaners, well they are history. And it did not eat any holes in the coveralls! I admit that I had already washed the suit at least twice, so what was left looked permanent. The end result could have been the combination of 14 different products, but maybe not. (I have no monetary interest in this product, except for the 2 quart jugs I bought at retail from WalMart. I have since used it on other stuff around the house. Great stuff.) Judy in Kentucky, USA
