Quartz kitchen countertops are easy to care for, usually only requiring a quick cleaning. Quartz is naturally stain-resistant, so even if something sits too long, a spot will be easy to remove.
Step 1 - Use a Sponge
First try placing a wet sponge with warm water over the stain, and allow it sit for three to five minutes to pull out the stain.
Step 2 - Try Vinegar
If this does not remove the discoloration, use vinegar on the sponge and try again for the same amount of time. When you remove the sponge, turn it over and use the scrubbing side of the sponge to gently scour away the rest of the stain.
