Sandy from Charlestown, Ma writes,

Gentrol stained the grout on my tile floor. The stain looks like oil stain. How can I remove it? Thanks....


We would recommend contacting the manufacturer directly for instructions on how to remove a stain. Generally, Gentrol Aerosol IGR will go on clear and dry that way as well. Their phone number is 415-562-6903.
