The former environmental services management used Perpetual Floor Shine and buffed, buffed, buffed. Now, it's very hard to remove. It has what is called AZO Dye, which may explain the yellowing in the floor tile. Anyone have any ideas/experience how to remove this?


Test different strippers on one tile at a time until you find a product and process that works. Azo dyes are synthetic colors used in food and fabric manufacture. Why any one would use yellow dye in a floor coating is unclear. Are you certain the yellowing is not the result of something else? Matting? Tracking, Recoating soiled tile? Burnishing in dirt?
Perpetual Floor Shine is a cleaner/restorer used as a spray buff chemical. I spoke with a local (Mattydale) contractor with experience in using the product and he had had no problem stripping floors where it had been used.
This may be a product compatibility issue.
