Hi, I'm chiming in because I have struggled with slow drains for 18 years at my house and I am liking bioclean. Here's my story, I live in a 100 year old house with very old galvanized tub and sink drain pipes that drain very slow because the inside of the pipes are caked with years of built-up sludge. About 2 years ago, I had a plumber cut out a 5 foot section of a 2" sink drain pipe and replace it because the galvanize pipe developed a leak (a small hole) from rot. When I did this, I personally saw that the passageway for water to drain in this pipe was about the size of a dime because of build-up inside of this 2" pipe. Snaking DOES NOT remove this sludge, the head of the snake just goes down the dime size path. Anyhow... I can't replace all the piping because 75% of my piping is hidden in walls and ceilings, so I decided to start using one of these products. I chose bioclean and I've been using bioclean for 2 years now and I finally see it working. The first year, the Bioclean creates a few blockages because it loosens the sludge and hair and that debris gets stuck in those dime size canals. Just like the directions say, a plunger usually forces the loosened debris through, sometimes I used a snake in that first year. However, it's been two years and I never snake anymore, so I am becoming a believer now too. it takes a long time (2 years!) for this good bacteria to really start eating through and loosen years of built-up sludge. I treat once a month. here's how I do it... I pour warm water into that cup they give you, and I stir in the dry bioclean and I let that warm cup with Bioclean sit on my counter for 20-25 minutes so these little critters can COME TO LIFE, then I pour the mix down the drain and try not to use that sink or tub for at least overnight (if not longer!) so the little critters can really build up their population and dig into the built up sludge and live within the sludge inside of the pipes. Whenever I go on vacation I do a treatment so it can REALLY build up in the pipes, while I am away. Unfortunately, liquid drain cleaners, bleach and things like mouthwash can kill the living bio-clean that are in your pipes so you have to keep that in mind and read all the paperwork they provide when you buy this stuff. This stuff does work, it's all about patience, using a plunger every once in a while during that first year and building up the population as well as doing it monthly and not killing the bacteria with household chemicals. Additionally, I think putting bioclean in a toilet is probably just wasting the product as you are simply flushing it down the drain at high speed into the sewer, you want to focus on sink and tub drains and for the bioclean to live and work (feast) within your sink and tub lines. It's been 2 Years and I'm finally starting to see results!
