You want PBW by Five Star Chemicals. To my knowledge, Oxyclean comes in two options, regular and free (free of perfumes and dies). It does not have a low foaming agent or rinse aid like PBW does.Second; can somebody tell me the brand name of the low-foaming oxyclean?? I bought the stuff at my dollar store as was mentioned on this thread, but i suspect it isn't the same stuff as mine has been foaming too much. Once it foams up a bit the holes in the shaft stop wirking as the water starts collecting in the carboy. The foam doesnt seem to be an issue till you actually get some crud mixed in the water, them the foam starts to form. Thanks!
