Upflush toilets are cleaned in two parts. Firstly, we have the macerator which is the most vital part of the toilet. Make sure that you clean it at least one or two times a year as mineral build-up can damage the functioning of the macerator. Then, we have the tank and the interior of the toilet. You have to clean these regularly, otherwise there will be foul odor in your bathroom. While cleaning, make sure that you remove any discoloration and so on.
