I have a quartz countertop that has a rust stain, how do I remove ?

Barkeepers Friend is my favorite, but you may as well seal the quartz once it is clean. White quartz will continue to get dirty and stained if it is not completely sealed. ☺️

I Googled it. It says to use soft scrub with bleach. Squirt some on your stain with a little bit of water to make a paste, spread it around on your Stain on your countertop and leave it sit for about an hour then just wipe it off with a paper towel

"cleaner from hardware store" really does not narrow it down much for us. Barkeeper's Friend will do the job for you. They sell it at the hardware store.

Barkeepers friend will do the trick!

Mix baking soda and lemon juice into a paste. Apply to stain let it sit for 15 or 20 minutes. Wipe clean. Repeat if there is still a shadow of the stain.

Thank you Google, thank you all! Just used Barkeeper's Friend to get out a big rust stain from a brand new matte finish quartz countertop! You are all lifesavers!

Glad Barkeepers friend worked for you.

Bar Keeper’s Friend would be my first choice, maybe something like Bon Ami, if they still make it (did I date myself?).

Baking soda will chemically absorb the rust stain, leaving your quartz countertops safe and clean. Step 1: Mix equal parts baking soda with equal parts water until it has a paste-like consistency. Step 2: Apply the baking soda paste to the affected area and let sit for 10-15 minutes.
