Hello,
Last year when I installed Engineered Stone behind my stove some of the watery mortar mix stained the stone. I am trying to figure out how to clean this off. All of my stone kind of looks brown because this.
Anyone know of a way?

what's manufacture recomend.Don't use muriatic acid,it will wash off the pigments in the colors.Use a firm nylon brissle brush and stop if you notice your colors are dissapearing.

muriatic acid is a bigggggg. NO NO 
..ive had some good luck with vinegar....but if the mortar cured for that long...it may be there for good.
The colors you see are paper thin...and stain pretty easy.
to much abrasion and they scar...
go slow....and good luck.
one more thing- spot check the vinegar someplace on ur wall- and try to avoid getting it on your grout joints- especially if your mortar was colored...

It's Stone Craft. The website is very vague about cleaning, however I did see somewhere suggesting vinegar.
I will try that this week.
Thanks
Neal

your probably out of luck, but, as suggested, try asking the mfg'r. High portland mortar that's been on there a while will be difficult to get off even using muritic acid (which you can't do) so I doubt much else will work.
That's why I like hard-fired red brick, make a mess, drop some mortar? no problem, wash w/ 50/50 acid solution, rinse off, done.
