I have read that bleach can yellow a white quartz so I'd stick to what the manufacturer recommends for stains and rinse well after cleaning. Most recommend Soft Scrub with Bleach. The only problem I've seen mentioned on the kitchen forum is surface pitting on Chinese quartz. I'd be wary of laying a hot hair implement on it and scorching the resin since you're not supposed to put hot pots directly on it in kitchen use.

R S Any sealer will harm the quartz surface it simply does not bind. Here are two photos from different jobs where we have had to repair the damage form sealers or color enhancers.... This is why they do not work.....! The cloudiness in the photo above is attempting to clean the surface and because the sealers do not bind or set, they are then impregnated with the cleaning compound. Which causes them to set. The issue is why they used it in the first place. They had etched the surface from using products like Gumption, BKF and Mould and Scum remover as most of the off the shelf cleaners including Green, Organic and Earth choice etc are all caustic. Meaning they have Sodium Salts in them and therefore have a high pH level. These will damage any stone or surface overtime... so it is not isolated to quartz. Formica is satin finish or matte, and why it will not show the damage but formica is basically cardboard that is printed and heat treated and attached to a timber or mdf substrate. Again my question would be WHY not if I can use it! Use the correct cleaner and you will be fine.... just remember that the likes of Caesarstone and they are not the only ones... Actually void their own warranties by recommending products that are outside the the pH levels or are solvents, harsh chemicals or abrasives. All of which void any manufacturers warranties. If push come to shove, they have left themselves liable for having the stone replaced at their expense. As what they are recommending on one hand , voids the warranty in the other. You have hit the nail on the head, why we would only recommend four major manufactures and you have named one. Note we have NOT NAMED any in this thread! ...........Forgive me...... I thought I heard a murmur from the gallery! Just in case the gallery forgot!

Our painter has done many homes' cabinets. They use a semi-gloss and it looks great. Just not sure how long-lasting it will be. (We will probably sell in 5 years.). The veining on the Botanica is pretty light. The older version of it - when it was made in China - was much darker.

There are all brands of engineered stone. The big manufacturers want you to believe they are somehow different. They aren't substantially; it's all the same stuff.
