Water falling on one's feet while washing

Q: Sometimes when using washroom there are back splashes at weird places which are difficult to wash like the sides. I try to wash those places after I am done but sometimes while washing the water falls on floor and on my feet. Is this water impure? Do I need to wash my feet and floor? Will I be impure and spread impurities? Also when using toilet if there are some impurities on the seat or shower, can I clean it by wetting the tissue and wiping it and then wiping with dry tissue because if I pour water, the impurities will spread on the floor making the floor napaak.

Removing impurity from the door

Q: If there is visible impurity from along time ago and was never cleaned what should I do? And how would I clean it since its on a closet door because I can't pour water on the doors. Also if I use a soaking wet tissue, if the water while wiping falls on the carpet will the carpet become napaak? I avoid those areas of impurities so after I do wudo and close the door where the impurity isn't there will I become napak? I have read namaz many times before after doing so, did they not count?

Toilet leakage problem

Q: There was leakage in the washroom ceiling and then it stopped by itself. There is a washroom on the top floor. The water from the leakage has dried now. If somebody uses the washroom and wet feet touch floor and they walk around the house will the house be impure. The floor was not washed after the leakage water dried. Is whole house impure and I can't pray there?
