Our house is about 20 years old. Some of the waste drains from both bathrooms have quite small PVC waste pipes. Even with daily use, the drains become smelly, despite efforts to use mechanical and chemical cleaning to clear them out. I tried the 10 x concentrate, both in the waste pipe plug holes and the cleaning mixture, in a spay bottle to clean surfaces and toilets.
After mechanical clearing of any hair or soap build up in the drains, I flushed them with a bucket of water. Good results with fresh smelling drains again. I regularly apply the spray mixture at the drain grates to help slow any build up of soap and hair.
I also use the spray mixture daily on kitchen work benches, stove top and touch surfaces like microwave door, fridge and cupboard doors and drawers, where they get spills and marks near the handles.
I am about to order another 5l of the Prozyme 10 x concentrate. It is more economical than a competitor’s product and leaves a fresh smell. A really good product that I would recommend to family and friends.
