Thanks for the suggestions. Im thinking it was a combination of the heat/humidity plus the dirtiness.
My solution is pretty simple using dawn and vinegar.
The second time they cane out better. But again the inside def needs to be done and completed when there is no classes going on…
I also just love having customers that say theres a problem days later after I follow up. Obviously i made sure to go and do another clean to take care of it, which when they said payment for coming out a second time i told them that it’s on me.
Curious how some of you guys/gals would handle that aspect of the situation…
