Amazing product. throw a few table spoon of the product in the drain, wait however long you want and run water in it and drain is all cleared. Work better than drano for like 10% of the price. no wonder Drano has to market more to make sure people don't shift to this simple chemical... yeah you can use a drain hook and other tool but my bathtub has non standard pipes i could NEVER get it to go the where the clog was (even with 20 feet wire).
