Yes I did a sample and it cleaned some
then I thought maybe the guy put some acrylic or something on it
so I sampled a little stripper with no effect. I also used her
hair dryer. very curious.
Thanks

Did
you test the grout and see if it’s clean?
Customer
called me years ago and said coit carpet cleaning was outer
and cleaned the grout.
Grout
looked dark and dirty, I did a test clean with her amway
soap and the grout came clean.
Hey All,
Looked at a porcelain tile floor, customer said she had it
cleaned and when the guy finished the grout was dark and
he said it would dry the proper color (lighter) it didn't
and when I tested it I couldn't get any results. I
noticed a hard color change in the closet where his
cleaner stained it and where it was light and clean. What
could cause the color to go dark? Strong Acid?
Thanks Stephen
