One last question on OxyClean. There are a couple of different "flavors" of the product and the one I have is called "Versatile" and says "Stain Remover, Chlorine Free." Is that what you all are using? The reason I ask is that I had something happen once when using the product that has caused me concern. I had several bottles in a plastic sink filled with hot water and OxyClean and after a few hours, I found a residual coating on the bottles that would come off with scrubbing, but I was reluctant to use the bottles because I did not know what was happening inside the bottles. I was wondering if I am using the "wrong" OxyClean. Thanks.
