Impurities

Q: A female servant washes clothes in my home. My wife puts both pure and impure clothes in a bucket and adds water and washing powder. Servant washes those clothes on washroom floor with a detergent. She throws the impure water from the bucket and fills that with new water. She does not clean the bucket before filling with new water. She rinses the washed clothes in that water. Again throws water and fills with new water without cleaning the bucket and again rinses clothes for second time. Also she does not squeese the clothes after rinsing. Are these clothes be considerd pure? 

As I have doubts about this method of washing , I wash my clothes seperately. But my wife's wet clothes washed in the above method come in contact with my wet clothes when we place them to dry. If my wife's clothes are considered impure, do my clothes also become impure as my wet clothes come in contact with them.

Q: Sometimes when I go to the bathroom I see a white spot/stain. The thing is that the stain is there when I am awake. I mean that if I don't sleep for a whole day and then see it is there. Even If I don't get aroused there is a spot. It doesn't feel wet and neither does my private part fell sticky or slimy like its covered nether does my skin. This case is when I haven't slept for whole day after changing underwear in morning. I don't even feel anything if it there or while coming out if something does come out

1. Am I impure?

2. Do I have to change my underwear and do I have to do ghusul? 

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...

Q: My husband bought chocolate the other day, the one he bought didn't have alcohol but I noticed some of the chocolates did have alcohol. Since the workers of the shop use one spatula to lift all the chocolates and give it to you, would this make my husband's hands and everything he subsequently touched after touching and eating the chocolate napaak?

Q: I read somewhere that ground, wall made of bricks and trees become tahir (paak) if najasat (on them) becomes dry and there is no trace of it present?

Q: Please explain the logic in this. A lizard fell on my mom, then my grandma told my mom to wash her head, then only can she perform Salah, otherwise it's not permissible, is that correct?

Q: Will handling haraam meat make ones's hands napaak?

Q: If a dogs saliva touches your hand, not your clothes and it is washed off properly can you read salaah?

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.

Q: My mother uses a sandle which she takes to the toilet also. A few times she accidentally stepped on my musallah. I touched the part and it was not wet. With my hand only, I clean the dust without using any water as I am not sure where she exactly stepped on. She also stepped on the musallah with her shoe which she wears when she goes outside. Do I have to wash the musallah? I am currently reading salaah on the same musallah. I have doubts about another musallahs because my nephew urinated on them and the house worker washed them. I dont know if she washed it thrice or not. Can I read salaah on them as she used a detergent?
