Soap scum...five years worth?
Hi all! I am new to the board and to the residential cleaning industry. I was given several customers from a person retiring from the business, and the customers are bi-weekly so I do not have any soap scum build up to deal with there. The bathrooms take a small amount to work, just maintenance really. Recently I have had "ministry" opportunities to clean two houses. One house in particular had soap scum build up of 5 years...this bathroom took 5 hours of cleaning with strong solution of PineSol and hot water, scrubbed with a sponge mop and brush. The other house had less build up, but it took 3 hours to clean the bathroom. So, my question is what cleaner/method works best for this type of problem? Thank you for your time and for this forum!
