Dark marks on quartz counters

last modified: last year



After a long battle with our installer, we finally got our island slab replaced with MSI Midnight Marquinia quartz. The installers wiped the counter down with acetone and denat alcohol after installation. We now have these dark marks left in various areas. Is this just residual adhesive from thr protective film that was removed? If so, should another methodical wipe of acetone take care of it?

The fabricator asked that we try to clean it off with glass cleaner, which as you can tell did not do the trick.

    Matte counters show everything. That should be an expectation for choosing them. A microfiber cloth, hot water, and Dawn, and then polish dry with a microfiber. Thst will get off the hand oils. But you will have to keep that on repeat play.

    Sorry if the picture didn’t show it well and I failed to mention it, but this is a polished slab. We’ve also already tried BKF soft cleaner and warm water and a microfiber. Always well rinsed aftwrward and polished dry.

    "We’ve also already tried BKF soft cleaner..."


    That may be the problem.


    I'd try some Tenax Quartz Toner.

    The spots were there

    immediately after the installers left. I tried the BKF after finding the spots. The BKF definitely didn’t cause

    them.

    Bar Keeper Friend liquid gets those streaks out.

    @KDC KITCHEN & BATH GALLERY, so from their post above I would say not always...................

    @User - if you click on the photo for full resolution, you can clearly see the dark splotches that I’m talking about. It certainly doesn’t look like different aggregates and resins. It has perfect little circles where acetone dribbled in the dark splotch.
