Q: I get frequent wet dreams. The problem is that it takes me about 30 mins daily to do ghusl. The main problem in ghusl is washing my feet which can take upto 20 mins because my feet has dirt inside the lines so I rub them with a pedicure stone until they are gone.

I am moving to a hostel for educational purposes and there I will have only few, maximum 5 mins for a bath as there will be a communal bathroom. Plus, the temperature can be 0°c or below too so I can't take a long bath. What do I do as I am becoming depressed due to this thing?
