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?
A: Wash it thrice and see that you rinse it out thoroughly.
You can wipe it out properly and thereafter perhaps rub it with a moist rag. The door will then be paak.
And Allah Ta’ala (الله تعالى) knows best.
