We also publish and circulate the East Public Toilet Guide, Toilet cleaning services etc in this book we do emphasize cleanliness but we need be advised on how you can clean the ecosan pan with water enter on either the faeces or the urine side.It is most likely that some users of the toilet may miss the hole and drop their poop on the pan surface such you need to use allot water and detergents to clean. What is the best way to do it?

Dear Mastulah,
It is not the water and detergent which you need to clean off faeces stains of a toilet. It is more the scrubbing action (hence the need for a good brush for flush toilets!).
Hence for a UDDT (or "ecosan toilet") just use a moist sponge or rag.

These two photos show examples for such cleaning:

(if it is not your own toilet, make sure you use gloves for added safety and comfort)
