Hi everyone! I have cleaning contracts with large office buildings ranging from 2 to 5 days per week. Dusting, vacuuming, mopping, restrooms, trash, etc... I include "spot cleaning" of glass and mirrors in my contracts. Complete window cleaning would be a separate job. Currently, we just spray window cleaner and wipe with paper towel. Not perfect, but sufficient for daily janitorial cleaning. I was just curious to see if there may be a tool or better way for us to quickly clean mirrors and glass in this scenario? One of my contracts (a boys and girls club) has dozens of doors with glass that they would consider having me spot clean everyday. Before I give them a price for cleaning using my current method, I thought I would run it past the forum first. Thanks!
