Impurities

Q: Sometimes after washing hands even properly, some soapy residue remains then I just clean it with tissue. Is that impure? Are my hands pure?

Q: I am a very doubtful person and I keep doubting myself over impurity. I have a few questions please help me make my life easier on me.

1. We take a shower in bathtub and during wudhu I wash my feet in there. On one side of the tub water collects and we have to drain it by pushing it with our feet towards the drain. So does my wudhu or ghusl qualify or do I have to wash then drain with feet and then wash again?

2. While washing my hands some soap which I had put on my hand touched a part of my hair. From the shoulder as my hair was falling off the shoulder. Does my hand become impure if it touches the soap on my hand which I had applied?

3. After Intimate relations between couples if after that you touch your phone or switch with that hand does it become impure. If impurity is dried off but hands are not washed and you touch it. Does it become impure if you touch other things? And if someone else touches the same things with wet hands, does that other person become impure?

Q: If washed alcohol glasses are kept and a pure utensil comes in contact with the glass like touches it will the pure utensil be impure.

Q: If utensils that may have come in contact with alcohol are washed in the dishwasher, do we have to clean the dishwasher. Can the utensils be pure to consume. What if I run the rinse cycle in dishwasher will it be pure to wash pure utensils.

Q: You have always helped me in my doubtful issues. I am a very doubtful person and often doubt purity. Please let me know if sperm drops on the floor and I can't figure out exactly where they fell and whatever I could see I cleaned them with a dry and wet tissue. Now I am doubting that what if I missed more spots or what if while finding the spots I stepped on one and now I feel the whole house will be impure wherever I will wear the slipper. Also if I have missed a spot and if I mop the floor will whole house be impure to pray.

Q: I have a graze on my front private part, a bit of skin came off. There is now a build up of water\pus there. The water\pus stayed within the wound before I had a shower. However after I had a shower I cannot be 100% sure if it flowed beyond the wound as I initially dried myself with a towel. It looked as if it had flowed out, but I couldn't be sure after checking several times. I suffer from constant waswas.

1. Do I regard it as non flowing?

2. Is my towel filthy as well now?

Q: Sometimes dreams are close to reality and you can't figure out at times. I'm unaware whether urine drops came out in my sleep or was it my doubt or a dream. I'm constantly doubting myself. I am a very doubtful person. Should I consider myself impure and the bedding or should I follow my doubt.

Q: Someone I know used to drink alcohol and use lipsticks right after having it. Now when she has purified herself if she uses the same lipsticks when she did after consuming alcohol will she become impure and spread impurity? Does she have to throw away all makeup used at that time. If she doesn't remember whether she used a particular lipstick after consuming alcohol and is doubtful, what should be done as makeup is expensive? Is their any way?

Q: I asked this question before as well but I was confused. If my husband drinks alcohol and immediately after that becomes intimate, do I become impure due to his saliva as it's very hectic taking bath again and again. Also during menses if a female does istinja and after istinja the water falls on the feet, is it impure?

Q: If one has any najasah on one's clothing and then one immerses oneself in a big pool etc will the clothing become pure if there is no traces left of the impurity?
