I wanted to ask two questions:

1) After doing urine i wash so while washing the water goes to scrotum, so is it pure or not? If not then what i should i do?

2) 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

1- You can consider it clean.
2- All what you need is to wipe the tray, whether by tissue or cloth. However, wiping will not make it pure.
