From Terri27

Richard was able to get out the blue crayon that [another company] could not!  My husband walked into the room and said “they did a better job then the last company” Aqualux was able to come at my convenience instead of a ” 3- 4 hour window” of time.  Want to try them on my grout cleaning and sealing.

Thank you Terri27!  Perhaps the last company just loosened up the stain a bit, making it easier for us to clean.  We hope to hear from you soon!
