  • Great drain cleaner!

    I used this product on all my drains throughout the house and it works like a miracle. Highly recommend this product. In fact, all of Professor Amos's products are exceptional. Thank you.

  • Great product!

    I had a very slow bathtub drain. The shower water would stand in the tub for hours. Tried just about everything, nothing helped. I used this once and saw improvement, so I used it a second time, now the water drains right out. Used it on the bathroom sink also, which was slow, clogged and gross. After 1 treatment, water rushed right out. No snaking, no plunging, no mess.Highly recommend and I will be purchasing more.

    My roommate stuff artichokes into the disposal. He called me and said the kitchen sink is clogged and he cannot fix it because he was tired. After a long work day I come home with the sink on a two inch standing water. I mix up the powder and poured it into the sink. I had to put more of it and waited - remember these were artichokes! It took about two hours and a little help with the septic cleaner - Prof Amos powder. You got to let the powder do its job - digest the stuff stuck in there. Finally I got the disposal to clear the clog. I am asking my room mate to buy 3 of this as payback. BTW for such a clog I did use up about half of the bottle in increments. it save us calling a plumber, save us time opening up the sink. Stock up!
