I've read all the posts about cleaning soap scum from "shower doors", but this concerns fiberglass tubs & showers. I clean for others (sometimes a 1 time cleaning), usually there's lots of soap scum build up, especially in shower floors. I like a lot of the commercial cleaners (they work nicely if you're cleaning on a regular basis. HOWEVER, it takes 3 or 4 applications of the cleaner when there's so much soap scum. Does anyone have a cleaner/technique that will remove soap scum without spending a TON OF TIME?

The other question is in regards to microfiber. How do you get rid of all the trapped lent and other particles? I wash mine separately, but still have all the particles trapped in the cloths. So I can't use these for glass cleaning as there's fuzz everywhere. Ideas?
