Problem with quartz is that industry is not telling the truth. Quartz is hardest material, harder than granite but the so called quartz slabs are not pure quartz, most of the quartz slabs has less than 60% quartz rest is all sort of industrial waste like granite/marble powder from quarry, glass and concrete and biggest culprit is the resin. Most manufacture states percentage of quartz vs resin by weight, this is just the marketing tactics, stone is heavier than plastic resin, if you look at volume most slab has 15-30% resin. Resin is biggest culprit when it comes to quartz staining and dull marks, resin is very soft material and it reacts with any household product like lemon juice, vinegar, wine, soap, tomato juice etc. and when you spill any kind of acidic/alkaline on quartz it creates etch mark, which looks like stain but it is a chemical reaction with resin, which you cannot get out unless you re-polish surface by professional guy. Even regular use abrasive object like magic eraser, or scotchbrite will create a dull mark when you rub quartz countertop with it for cleaning, it is cutting though soft resin and destroying fine finish. Quartz need to be treated like a baby, it is good for display in galley but not for daily use in kitchen. Egypt pyramid has granite which has withstand 3000-4000 year of abuse but todays quartz cannot withstand normal use and tear of daily kitchen activity. I made mistake of installing quartz, but I will never go back to quartz natural stone/granite is best option for me.

All these posts make me sad- I was hoping there was a simple solution of just having the countertops repolished 😕 i have a handprint, a spot that looks like lattice sat on it , a couple of square spots and multipe cloudy areas. Leaving full bight kitchen light on is only solution as that is when u can see it the very least. so frustrating- lots of $$… I want my old coutertops back and regret thinking that Quartz was so durable and easy to care for!! not!!! i also wish i had used the installer that cost more through the place the coutertops were purchased- thought i was saving $1500 - mistake
