I cut into one of my waste pipes this weekend (to replace my bath drain) and found a thick layer of brown sludge. The pipes are not blocked but they will be soon.

I have started to use Bioclean: bacteria that eats biological sludge. Does this stuff really work? Since I will not be opening the pipe up again any time soon, I would be grateful if any of you have seen the ‘before’ and ‘after’ with this stuff.

I have sold many jars of Bioclean over the years but do not know for sure if it actually worked. I read the lititure ect but don’t know for sure. It was pushed by the company I worked for at the time to sell it and I made five bucks on everyone I sold.
