Frequently Asked Questions
Are the Dishwashing tablets and Universal Cleaner septic safe?
Both the Dishwashing tablets and Universal Cleaner are safe for septic systems.
Do you need to use rinse aid with the Dishwashing tablets?
Rinse aids were originally developed for harder water regions. If you live in a hard water region, we would recommend the use of a rinse aid. As a guide, the southern and eastern regions of the UK have hard water.
How long will the refill bundle last?
Our Universal Cleaner lasts for 2 months for a standard 2-3 bedroom home when used as an everyday cleaner in conjunction with the Koh cleaning system. The 2 x Dishwashing tablet packs (100 in total), will last the typical English household between 60 and 90 days.
