Advanced cleaning is a preventive way to ensure you keep your Rotimatic in good health all the time. This doesn't mean that the water pipes are unclean.
A residue might only be seen for people who did use milk or any other substance in the water container. If you have been using only water during roti making, you might not see any residue coming out but be rest assured that the water pipe has been cleaned.
We recommend this cleaning process to be done regularly, once every month, to ensure your Rotimatic performs well
