I use western toliet and there are 4 people living with me in the house so whenever I go to washroom, I find water on the toilet tray/plate. How can I clean that? I have read on internet I can use tissues but how many times will I use? It is a wastage of tissues so is there any other way to clean the toilet plate/tray? Or i was thinking I could use a cloth to clean the plate/tray so is it okay?

If the water on the toilet seat is najes, then tissues or pieces of cloth will not purify it. Only water can purify it. You can slowly pour water on it from a water can, and let the water spill at an angle so it pours into the toilet and not on the ground. Pour water twice on it and that would purify it.
