Impurities on clothing and furniture

Cleaning impurities from clothing

Q: We have a washerman, who after cleaning the clothes with detergent uses hodees (small water ponds to store water) to wash them completely. He uses 3 or 4 such hodees such that after putting clothes in one, he puts them in the other to remove the remains of the detergent... Will it suffice to make the najis clothes paak if one finds no signs of najasat afterwards...

Incontinence problem

Q: I'm a male and I have a medical problem of urethral discharge incontinence. I can't afford to buy diapers everytime and also there is not too much of leakage, only small amounts. I keep a tissue paper in my underwear to prevent it from soiling. But it always keeps moving from it's place. I tried wrapping around my penis but still it unwraps and moves away. So, everytime when I'm going to toilet, I change my underwear also. Nowadays, I am changing 6-7 underwear per day, which is very very difficult. Please tell me any other suggestion, so that I don't have to change my underwear everytime when I go to the toilet.

Cleaning a soiled sofa

Q: My neice diaper leaked and i did not know... I allowed her to sit on the sofa and as soon as she sat, a spot appeared on the sofa, I asked her to get up and changed the diaper. As a precaution I wiped the place with surf and then with a wet cloth. The next day I cleaned the sofa by pouring water over the spot three times. Has it become paak because my mother offers prayers by sitting on that sofa thats why I am concerned? Plus the water reached on the lower part of the sofa which becomes a bed. Does that part become napaak as I read somewhere that if you clean something with a jug of water, the water which flows is napaak? Keeping in mind it was just a spot which did not go on the lower part of the sofa. Also explain for the future how to clean a sofa matress, etc. if a child urinates on it?
