Hi all. I found a bargain at a local thrift store and scored a few cases of Promise diapers dirt cheap ($4 a pack). I've been wearing them constantly with plastic pants. The diapers have a faint print along the wetness indicator that appears to be a lot number and size info. I've found that the ink is staining my nice white and clear plastic pants so that there is now an unsightly grey stain in the front . I tried using a little rubbing alcohol, but the stain won't come out. Anyone have any ideas?
