Quartz countertops are popular in many homes due to their durability, stylish appearance, and low maintenance. However, like any surface, quartz can get stained over time with spills and exposure to moisture. Rust stains are one of the more stubborn stains that can occur on quartz. Rust can result from having metal objects sitting on the countertop that rust or corrode. The iron oxide in the rust bonds strongly to the surface and can be tricky to remove if you don’t use the right methods.
The key is using the right rust removers and techniques to lift the stain without damaging the quartz. Quartz is very hard so abrasives and harsh chemicals are not recommended. With some persistence and the proper products, you can get the rust stains off your quartz and have it looking like new again. Here is a detailed guide on the most effective ways to remove those unsightly rust stains from your quartz countertops.
Cleaning Supplies You Will Need
Before tackling rust on quartz, make sure you have the right supplies on hand. Here are the recommended products:
- Distilled white vinegar
- Baking soda
- Hydrogen peroxide
- Soft clean cloths and paper towels
- Plastic scraper or wooden spoon
- Non-abrasive scrub pad
- Acetone or denatured alcohol (only for very stubborn stains)
- Clean water
- Quartz cleaner or stone cleaner
- Optional: Magic eraser
Avoid using any abrasive cleaners, powders, or scouring pads on the quartz as they can damage the finish. Also steer clear of bleach, ammonia, and alkaline cleaners which can etch or discolor quartz over time. Stick to gentle cleaning solutions when possible.
Pre-Cleaning Steps
Before treating the rust stain, do a bit of prep work:
- Sweep or wipe away any dirt or debris from the countertop so you have a clean surface to work on.
- Inspect the stain to identify the source of the rust and remove it. This prevents continued staining.
- Rinse the stained area with clean water and let dry completely.
- Test your cleaning solutions on an inconspicuous part of the quartz first to ensure it doesn’t etch or discolor the stone.
Once the countertop is prepped, you can start tackling that pesky rust stain. Here are the methods to try:
Baking Soda Paste
Baking soda is mildly abrasive so it can help lift rust stains without damaging quartz. Mix it with water to form a paste:
- Add 3-4 tablespoons of baking soda to a small bowl
- Stir in just enough water to form a spreadable paste, about 1-2 tablespoons
- Use a soft cloth to rub the paste gently over the rust stain
- Let it sit for 5-10 minutes before rinsing clean with water
- Dry thoroughly and check if more applications are needed
The baking soda paste is often effective for light or surface rust stains on quartz.
Vinegar Solution
As a mild acid, distilled white vinegar can dissolve rust stains and mineral deposits. Follow these steps:
- Mix equal parts vinegar and water in a small bowl
- Dip a soft cloth into the solution and wring out excess liquid
- Gently rub the damp cloth over the stain for 3-5 minutes
- Rinse the area thoroughly with clean water and dry with a towel
- Repeat as needed until the stain lightens up
Vinegar is safe for quartz but test first, as prolonged exposure can etch some quartz varieties.
Hydrogen Peroxide
Hydrogen peroxide is another mild acid that can help break down rust stains without damaging quartz. Follow a similar method:
- Pour some hydrogen peroxide directly onto the stained area
- Let it sit for 2-3 minutes before blotting with a paper towel
- You can also dip a cloth in hydrogen peroxide and rub it onto the stain
- Rinse thoroughly with water after application
- Reapply a few times if needed to lift the stain
Hydrogen peroxide can lighten or discolor some quartz so spot test first. Limit contact time to prevent unintended damage.
Magic Eraser
The melamine foam material of magic erasers makes them mildly abrasive. With a delicate touch, they can lift rust stains from quartz:
- Dampen a magic eraser slightly and wring out excess water
- Gently rub it over the stained area using minimal pressure
- Check often to avoid scratches
- Rinse and dry the surface afterwards
- Repeat if needed but discontinue use if the eraser damages the finish
Magic erasers work best for surface level stains. Be very gentle as you don’t want to scratch or dull the quartz.
Acetone (Stubborn Stains)
For really stubborn rust that won’t budge, a solvent like acetone may be required. Use it cautiously:
- Dip a cloth or paper towel in acetone and rub gently over the stain
- Check every few seconds and rinse with water as soon as the stain lifts
- Avoid rubbing too hard or leaving acetone on too long as it can damage quartz
- Spot test first to see if your quartz has any adverse reactions
- Limit contact time and use as sparingly as possible
Acetone is powerful so approach with care on quartz. Try the other methods first before attempting this one.
Commercial Rust Removers
There are also commercial rust removing products made specifically for stone and quartz:
- StoneTech Restore Quartz & Granite Countertop Cleaner – Spray and wipe formula with oxalic and phosphoric acid to dissolve rust stains
- Granite Gold Rust Remover – Gel formula clings to vertical surfaces, safe for quartz

- Weiman Granite & Stone Cleaner – Foaming spray helps lift rust stains from quartz
Always follow the product instructions carefully and test on a small area first. Look for ones that specify safe use on quartz/engineered stone.
Preventing Future Rust Stains
Once you’ve conquered the rust stains, take steps to prevent new ones from forming:
- Wipe up spills quickly to avoid moisture sitting on the quartz
- Use coasters under metal pans and containers
- Avoid leaving cast iron cookware, pots, pans, or utensils sitting directly on the quartz
- Seal quartz countertops annually with a stone sealer to add protection
- Clean quartz regularly with a pH-neutral stone cleaner
With proper care and prompt stain removal, you can keep your quartz counters rust-free for years to come. Be patient when removing rust stains – it may take a few tries. But with the right gentle cleaners and techniques, you can restore the pristine look of your quartz.
Frequently Asked Questions About Removing Rust From Quartz Countertops
Can I use bleach to remove rust stains from quartz?
No, avoid using bleach or other harsh alkaline cleaners on quartz counters. The chemicals in bleach can damage, fade, or etch quartz over time. Opt for more gentle cleaning solutions when removing rust from quartz.
What about using lemon juice or vinegar to remove rust?
Lemon juice and vinegar are both acidic which makes them useful for dissolving rust stains. However, all acids can potentially etch or dull the surface of quartz if left on too long. Rinse immediately after application and spot test first before using lemon juice or vinegar as a rust remover on quartz.
Will a pumice stone successfully remove rust from quartz?
No, steer clear of pumice stones, powders, or other abrasives on quartz counters. The gritty texture and friction from a pumice stone risks permanently scratching or dulling the smooth factory finish of quartz. Use only non-abrasive cleaning solutions and tools instead.
Is it okay to use oven cleaner to remove stubborn rust stains from quartz?
No, avoid using harsh caustic oven cleaners on quartz counters. These cleaners are much too alkaline and abrasive for quartz, often containing lye or sodium hydroxide which can etch or damage quartz. Stick to gentle cleaners specifically formulated to be safe on engineered stone.
Can I remove rust from my quartz sink the same way as the countertops?
Yes, you can use most of the same rust removal methods for quartz sinks as for countertops. Just remember to be cautious using abrasives or corrosive cleaners since scratches and etching will be more visible in a sink basin. Test cleaners on the underside of the sink first before applying to visible surfaces.
How can I prevent rust stains from forming on my quartz countertops?
Prevent rust stains by promptly wiping up moisture, using coasters under metal objects, sealing the quartz annually, avoiding cast iron cookware directly on the surface, and cleaning quartz regularly with a pH balanced stone cleaner. Taking preventive steps will minimize the chances of stubborn rust stains developing.
Will a rust stain permanently damage my quartz countertop?
Most rust stains can be removed from quartz surfaces without permanent damage, as long as you use the proper cleaning methods. However, if left for prolonged periods, the iron oxide in the rust can bond strongly and potentially etch into the quartz. The sooner you treat rust stains, the less likely they are to become a permanent eyesore.
Is it safe to use a magic eraser on quartz countertops?
Yes, magic erasers can be safe for quartz if used cautiously. Dampen the eraser first and only apply minimal pressure as you rub. The melamine foam material is mildly abrasive so take care not to rub too aggressively. Spot test first and discontinue use if you see any scratching or dulling of the surface.
How can I tell if a countertop rust remover is safe to use on quartz?
Read the product label carefully to verify it is approved for use on engineered stone and quartz materials. Avoid rust removers with harsh acids or alkaline ingredients. Look for ones with “gentle” formulas made for stone and quartz. Do a patch test on an inconspicuous area first before applying to visible sections of the countertop.
