Impurities on the body

Washing dried semen

Q: I had released semen at night which had dried on my private area when I woke up in morning. When I did ghusl, the dried semen was not coming out, even after scratching or rubbing the skin. I left it and completed my ghusl, and offered fajr. This dried semen did not come out until I scratched it again after a week, and even then I think it did not come out completely.

1. Does this dried semen keep me impure?

2. Will I have to repeat the prayers I offered with this?

Touching impure dry items

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?

Cleaning urine drops from a shoe and one's feet

Q:

1. How to make a shoe paak which has urine drops? I put water over it three times. I am not finding anywhere how to make a shoe paak

2. If I wash a chicken for cooking and its blood flows in the wash sink, does it make the wash basin napaak? Also, is it necessary to make a cloth paak if the blood of that chicken sticks on it?

3. If someone gets urine drops on feet and then wash it with soap and pour water on feet twice or thrice, is it sufficient or is there any other way to get it paak? Can the same method of washing be applied if someone gets urine on any other part of the body?

How many times should one wash impurity off one's hands?

Q: I want to ask that if one's hands are very dirty e.g. if urine drops can be seen on one's hands then how many times should the hands be washed. Beyond that limit of washing, will it be a sin. I'm asking this because I'm getting mad day by day as I wash my hands for 20 to 25 times with soap, so it very irritatating to wash so many times as I'm not getting satisfied that my hands are now clean.
