Bio-Clean is one of those products that have so many uses. Take it into any room with a drain and it can be used there. It will clean the shower drain that has slowed down due to hair and soap scum. It will work on that toilet drain to get it working the way it did when it was new. Use it in the kitchen to work on the build-up that has accumulated in the garbage disposal and sink drain. If you have a septic tank Bio-Clean is a must have.
