What Causes Rust on Quartz?
Rust forms when iron or steel comes into contact with moisture. On a quartz countertop, rust stains can develop when:
- Cast iron pans or cookware are left on the surface
- Rusty water drips onto the countertop
- Iron-containing cleaning products sit on the surface
- Metal objects like nails or tools are placed on the quartz
The iron oxide in the rust bonds to the quartz, resulting in yellowish or reddish discoloration. If left untreated, the stain can become permanent.
How to Remove Rust Stains from Quartz Countertops
Step 1: Act Quickly
Address any rust stains on quartz as soon as possible. The longer the rust sits, the harder it’ll be to remove. Immediately wipe up any water or moisture that contacts metal on the countertop.
Step 2: Try a Soft Scrub
For light rust stains, mix together baking soda and lemon juice or vinegar into a spreadable paste. Apply the paste to the rust stain and let it sit for 5-10 minutes. Scrub gently with a soft cloth or sponge. Rinse with clean water and dry thoroughly.
Step 3: Use a De-Ruster
For stubborn rust stains, apply a store-bought rust remover designed for stone and quartz. Popular options are Iron-Out and Whink Rust Remover. Spray or pour the product directly onto the stain. Let it sit for 5-10 minutes, then scrub with a nylon brush or Scotch-Brite pad. Rinse thoroughly with water.
Step 4: Try Bar Keepers Friend
If other cleaners fail, Bar Keepers Friend is a mildly abrasive cleanser that can lift rust off quartz. Make a paste with water and apply to the stain. Let it sit for 10 minutes before scrubbing in circular motions with a sponge or nylon pad. Rinse and dry completely afterwards.
Step 5: Use Oxalic Acid
For extremely stubborn rust that won’t budge, apply an oxalic acid-based rust remover. Products like Goof-Off contain oxalic acid to break down rust. Spot test first and strictly follow product instructions. Rinse repeatedly. Oxalic acid can damage quartz if left on too long.
Step 6: Buff with Baking Soda
Once the stain is gone, mix baking soda with water into a spreadable paste. Use a microfiber cloth to buff the paste onto the cleaned area. This helps neutralize any lingering residue left behind by cleaners. Rinse and dry the countertop.
