Hello, am I welcome here

I am located in Irvine Ca, my company is called Shine Time Cleaning Services. I currently limit my business to standard cleaning services. I found deep cleaning seems to have a higher cost some can't afford. I currently have one dependable employee so along with her and myself we do 3 and higher houses, I do the 1 and 2 bedrooms myself. I am anxious to get some time-saving ideas that clean the homes faster but still get all the customers' requests handled. My major area is soap scum shower doors (the ones where people haven't cleaned them for years?) I currently use Bar Keepers Friend powder, RMR extreme soap scum remover, and a buffer for those jobs, but some scum remains Any good suggestions?
