Not all bases are alkali but all alkali is base. |

I dunno...
Third Base? 
IIRC, ammonia is more used as a buffering agent than alkali. I'm not totally remembering the cleaning action reason - I think it is saponification or a variation of that. Could be wrong. |

It's not a stain, it is a burn. Permanent damage.

Hmm well I guess if it's a burn and permanent damage, then trying the sealant again wouldn't hurt it further?
I guess it really might pay to have an expert come out and see.
In the meantime- isn't there a pretty bowl or vase you can place there ?
Said in jest but only partially.
wink wink

Try hydrogen peroxide. You might also try non-abrasive comet or Bon Ami or bar keepers friend. Those cleaners contain ingredients that break down various deposits. Do you homework first though and make sure it is ok to use those on granite. If that doesn't work, you have most likely more or less cooked whatever was in the Windex and it make have created a sort of crystalline ring in the porous surface of the granite. The only resolution may be buffing and polishing the granite to remove the ring.
Even though you will read that it is okay to place hot pans on granite, do not ever do so. Whatever may be on the granite such as spills or residue from where you were preparing food or even cleaning may burn and create marks and rings. Its best to always place something such as a privet on the granite and then place the hot pan on it.

Granite doesn't burn though, does it? Is it possible that the waxy sealant was scorched? |

Uhhh, I think you meant trivet. If you want privet (an invasive plant in Alabama) I can provide you with a lifetime supply.
My real question is "WHY granite, except for following the herd instincts of the wealthy?" I grew up around granite. I tore up my knees falling off a bike onto a crushed granite street. Granite makes great gravestones and rip-rap that will last forever, but using it for a countertop means extra care to prevent problems like the one in this thread, broken china and glasses, and regular warnings to kids and guests that can be a source of discord. The function of a kitchen is cooking and making food. If you want a wow factor, why not put in a stained glass window or some decoration that won't interfere with NORMAL counter uses? |
