Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.
Quick answer
Water rings on quartz and Caesarstone are mineral deposits left behind as water evaporates, because the surface is non-porous and nothing soaks in. Wipe with warm soapy water, then use a cleaner approved by your quartz manufacturer for anything left, and dry with microfibre.
First, check what you are dealing with
- White or cloudy ring on the surface: mineral deposit.
- Ring that will not clean off on quartz near a hot area: possibly heat damage.
What you need
- Warm water and dish liquid
- Microfibre cloth
- Manufacturer-approved cleaner
Step by step
Wash the area
Clean with warm water and a few drops of pH-neutral dish liquid, rinse and dry with a soft cloth so you can see what is left on the quartz.
Dissolve the minerals
Use a cleaner your quartz manufacturer approves for limescale, following the label.
Rinse and dry
Rinse with clean water and dry with microfibre so new spots do not form.
What not to use on quartz
- Scourers, steel wool and abrasive creams on a polished surface.
- Mixing cleaning chemicals, especially bleach with anything else.
- Oven cleaner, paint stripper and strong alkaline degreasers, which damage the resin.
When to call a professional
A benchtop repairer can fix chips and some surface damage. Because Australia banned new engineered stone in 2024, repairs and protection are how existing tops are kept looking good.
Understanding water rings and marks on quartz
Quartz (engineered stone) is crushed quartz bound in resin. It is essentially non-porous, so most stains sit on or just in the resin at the surface.

Good to know
Water marks on dark quartz are almost always dried minerals. Drying the benchtop after wiping stops them forming.
