Just watched the MB dvd after a while since I'm going to start with a HP soon. Now I noticed the cleaning process, after he removes the glue, he shampoo's the hair and the lace while its unattached in the sink. Does anyone do this?

The problem is that I share bathroom and I wouldnt feel save having all this done with others who could walk in on me. And besides that I dont have any immediate acces to streaming water from another source.

Is this solvable?

yes..lock the door.
