Well, we’ve learned a few things. Cholula and mustard will leave a stain. First pass was warm water and dish soap. I followed that with rubbing alcohol and it cleaned them all right up- mostly. The mustard was stubborn on the stratus quartz but a paste of baking soda and 409 helped. Still had a slight halo but I bet if I’d left it on longer it would’ve eventually come out. So- No, your quartz will not stain but extra potent pigments might require a little elbow grease.
