Ask a Question
  • Is this safe for tinted commercial windows?

    We would not recommend this for tinted glass.

  • Is this product safe on all tile and grout? Also, does the haze easily come off as in the video?

    Hi Deb, yes it is safe to use on tile and grout, and depending on the level of build-up you have, you may need to tackle it once or twice more, but it comes off quite well with JFlint.
