Personally, I would not use it on quartz. If there is an occasional stain, I use Soft Scrub with bleach. And actually, it is good to just use it on the whole counter top on a regularly.

No Vinegar has the same pH level as hydrochloric acid. pH3 and baking soda is an abrasive

If you look at the care & maintenance instructions from the quartz manufacturer and also read their warranty cards. They will say not to use anything that is not pH neutral. Bleach, Vinegar, etc are all corrosive and will dull the surfaces overtime.

Bleach is also mentioned NOT TO BE USED by all the major manufacturers.

This is what bleach can do on both dark and light colours

Whilst it can be repaired by a very limited number or specialised stonemasons (use only stonemasons as this is their trade and the master masons understand stone fully) It is expensive to correctly repair back to the original finish and shine. No just blending and a bandaid fix.

We HIGHLY SUGGEST you use something like these products they will remove all stains from quartz countertops without damage

I’ve sprayed mine with 50% vinegar for 3 years without any issues. That Cambria statement is not very clear. I think it means “no strong acids,” but without a definition, that is pretty useless. It can’t mean nothing “ high, neutral or low pH”, because everything falls into one of those categories.

I’ve never had any stains, and I just spray and wipe with either the diluted vinegar or Mrs Meyers. Nothing abrasive.

please use limelite limescale remover on quartz. it will take away all stains wine turmeric coffee anything.

rose pinker and half your hand. Has a lower pH than hydrochloric acid, again DO NOT RECOMMEND things that are a) DANGEROUS and b) EXTREMELY corrosive c) will void, destroy any stone let alone Quartz of any brand.

Section 8 is what I would be reading. Also pH 2.5 is NOT slightly acidic... the scale for acids is 1-6.5 and 1 being the strongest. So 2.5 is NOT SLIGHTLY ACIDIC!

Again our Power Clean will remove all stains without the damage, is pH neutral and natural.

ledmond10 YES it does mean everything that is <6 and >7.5 pH as they are know to cause issues or damage to any stone including quartz

i have been using limelite for over a year and half. i have white quartz and limelite is very mild and no damage . i wish i can show image its as sprkly as i bought year and half ago. you can always try on the sample if not sure before using on actual product. my quartz cost me over three grand so i would not be using if it damages !

rose pinker if you think limelite is MILD you are insane, sorry but it is highly corrosive and you should read the msds link. We repair all stone counters and especially quartz and one of the only companies in the world able to. So we do know what we are talking about.

You can use whatever you like, but you have been warned. If you doubt us, ring the company that makes the quartz you have and ask them if what you are using would VOID your warranty. I am going to say YES

yes proof is in the pudding. the first image shows turmeric stains and the last image its gone without any damage to the quartz worktop !
