Istibra

Q:

1. I have asked many question regarding mazoori but I still have one doubt. I am suffering from urine drops problem and I am a mazoor. I wanted to ask after washing my private part during istinjaa, can I dry my private part with tissue paper? Remember I am a mazoor and when I try to dry my private part with tissue there is water and urine both mixed?

2. Because I am a mazoor, I keep tissue paper for example after performing istinjaa. I keep tissue make wudhu pray Asr and then I recite Qur'an and when maghrib time comes I only renew my wudhu. Will my Maghrib Salaah be valid?

Mazi coming on clothing

Q: I am 25 years unmarried boy, I know what is mani and wadhi and when to do wudhu and ghusl. My question what is the amount of Madhi should be there in order to wash cloths and private parts. I used to work in night shifts and most of times due to cold and sometimes even if I do a bit delay to urine I got madhi but the amount is very less. Its not even area covered by 1 drop of water.It's very small like a fraction of drop. Sometimes I have to look very closely and then I got a shine through which I realise its madhi. Now in this case must I wash my body and cloths or I just to do "wudhu"(ablution) without washing and changing. This is a problem for me as I have to go to washroom and wash myself and change my clothes sometimes twice a day.
