Hey guys I thought I would ask every on on hydrogen peroxide on witch to get %35 or %50 to make acid peroxide for ecrap. I have found a great great source on cems. If your in the USA you might want to get in touch with a compnay called Brenntag. So far I feel the cems are price good and getting them shipped is easy. I got Nitric, hydrochloric and sodium metabisulfite for about $430.00 shipped. That was 50lbs of sodium, 6x 2.2l of nitric and 5gal of Hydrochloric. I thought it was alright. Any thoughts.
