BiO HY drain cleaner

application and dosage

Dilute the concentrate about 5% with hot water (about 50ml / 1 liter of water). Then pour the mixture into the spout and leave it on for at least 30 minutes. Then rinse with clear water. If the pipe is blocked, please first remove the water from the basin and then proceed as above. If after 30 minutes the water does not flow out quickly enough when you carefully turn on the cold water tap, repeat the process. The drain cleaner is also suitable for thawing frozen drains. Important: Do not use an aluminum container and close the bottle well after use! Please note the instructions for use.
