Quartz countertops are a popular choice for kitchens and bathrooms because of their durability, stain resistance, and sleek appearance. However, even this sturdy material can get rust stains over time. Rust on quartz is usually caused by metal objects like pans or hardware coming into contact with the surface. The good news is that rust stains can be removed from quartz with the right techniques and products. Here is a step-by-step guide on how to get those stubborn rust marks off your quartz countertops.
What Causes Rust on Quartz?
Quartz is non-porous, so spills and stains have a hard time penetrating the material. But given enough time and exposure, even quartz can get stained by rust. The most common causes include:
- Leaving cast iron cookware on the countertop. The iron can rub off and cause orange stains.
- Wet metal objects like tools or utensils resting on the surface and causing rust marks.
- Imperfections in the quartz that allow rust from metal sinks, faucets or appliances to transfer.
- Iron or rust in the water supply, leading to stains over time.
While quartz won’t rust itself, the iron from these sources can leave stubborn stains if not promptly removed.
Cleaning Rust Stains from Quartz Countertops
Removing rust from quartz requires using the right cleaning solutions and techniques tailored to this material. Here are the recommended steps to follow:
Step 1: Blot the Stain
First, wipe away any extra rust on the surface with a dry towel. This prevents the stain from setting deeper into the stone. Don’t use a wet cloth yet – moisture can make the rust stain spread.
Step 2: Make a Baking Soda Paste
Mix baking soda with just enough water to form a spreadable paste. Baking soda is mildly abrasive so it will help lift the rust stain without damaging the quartz.
Step 3: Apply the Paste and Let Sit
Spread the baking soda paste gently over the rust stain and let it sit for at least an hour. If the rust mark is especially stubborn, leave the paste on overnight. This gives the baking soda time to draw out the stain.
Step 4: Scrub and Rinse
Use a soft scrub brush or sponge to gently scrub the paste over the stain. The baking soda will work to lift the rust away from the quartz. Rinse thoroughly with clean water.
Step 5: Use Vinegar
If any rust remains after scrubbing, use some white vinegar to help dissolve it away. Pour undiluted vinegar over the stain and let sit for 5-10 minutes before rinsing. The acetic acid in vinegar breaks down rust effectively.
Step 6: Try Barkeepers Friend
For really persistent rust marks, reach for Barkeepers Friend cleaner. This oxalic acid-based product targets tough mineral stains. Make a paste with a little water, apply to the stain and scrub. Rinse thoroughly afterwards.
Prevention Tips
Once you’ve conquered the rust stains, keep them from coming back with these preventive measures:
- Dry metal items like pots and pans immediately after washing. Don’t let them air dry on quartz.
- Use coasters under containers and drinks.
- Seal any cracks or chips in quartz with epoxy resin to prevent rust transferring.
- Clean spills right away to prevent stains.
- Consider a penetrating quartz sealer to make the surface more stain resistant.
Can You Sand Out Rust Stains from Quartz?
It’s not recommended to sand quartz countertops yourself to remove stains. The material is very hard so DIY sanding likely won’t work and could damage the surface. Leave it to the pros if stains are so set that sanding/resurfacing is needed.
When to Call a Professional
For light rust stains, the baking soda, vinegar and cleaning product methods should successfully remove the marks. But if you have extensive rust damage or stains that are extremely stubborn, call in a professional quartz fabricator. They have industrial tools and techniques to sand out and re-polish the surface.
Removing rust from quartz countertops is very doable with the right staining-fighting recipes. A little baking soda paste does wonders. But avoid letting metal objects make contact with the surface to prevent rust in the first place. With prompt rust removal and preventive care, your beautiful quartz countertops will stay looking like new for years.
Frequently Asked Questions About Removing Rust from Quartz Countertops
Can I use lemon juice to remove rust from quartz?
Yes, lemon juice can help remove rust stains from quartz due to the citric acid it contains. Simply rub lemon juice over the stain, let sit for 5-10 minutes, then scrub and rinse away. This natural acid works similarly to vinegar.
What about using bleach to remove rust stains from quartz?
Avoid using bleach or harsh chemicals like alkaline drain cleaners on quartz countertops. They can damage and discolor the surface over time. Mild acid solutions are safest for stain removal.
How can I prevent pans from rusting and staining my quartz countertop?
Always use hot pads or trivets when placing cast iron pans on quartz. Letting them directly contact the surface can allow rust to transfer. Also, dry pans thoroughly after washing and apply a light coating of oil to prevent rusting.
Why is my quartz countertop getting rust stains around the sink area?
Rust stains around a sink often indicate rust inside the metal pipes and fixtures. Replacing any corroded supply lines and treating your water can help. Also thoroughly dry the area after use to prevent transfer of water deposits onto the quartz.
Can I use a Magic Eraser to scrub rust stains off my quartz?
Magic Erasers are fine for cleaning quartz as long as you use a light touch. But for rust stains, a baking soda paste works better. Magic Erasers are not acidic enough to break down stubborn rust marks.
