Water on the toilet seat after flushing

Assalam Alaikum,

I wanted to ask you that when you go to the toilet do you have to wipe the toilet seat with dry toilet paper or wet toilet paper before sitting on it?

The toilet seat has drops of water from the flush so I’m unsure how to clean it before using it? �Can you please tell me?

Is the flush water pure water that goes on the toilet seat after flushing paak or is it napaak water?

Jazakallah
