Frequently Asked Questions 

Q: How often should I use this cleaner?
Use it 2-3 times per year (every few months) for maintenance, or whenever you notice odours, sluggish drains or scale build-up. Using it regularly helps prevent heavy buildup which is harder to remove.

Q: Will this clean both waste tanks and grey water tanks?
Yes , it’s formulated for both. Grey water tanks often get grease, soap and dinner wash-off, while waste tanks get more solid/chemical deposit buildup.

Q: If I have only one tank (e.g. waste tank), is the grey water instructions needed?
No , just use the instructions relevant for the tank you are cleaning. If you have both, you can use grey water instructions for that tank.
