Rust stain removal checklist

Short answer: gather gloves, sealed eye protection, a plastic sprayer, rust remover, a hose and the right brush. Identify the stain, protect plants, pre-wet, test a hidden spot, apply, keep it wet for the surface's dwell time, scrub gently, rinse well and flush the sprayer. Print this page and tick off each box as you go.

Gear list

Same compound as spinach. Way less friendly than a salad.

Protection

• [ ] Chemical-resistant gloves, nitrile or rubber
• [ ] Sealed goggles or splash glasses, not regular sunglasses
• [ ] Closed shoes and long sleeves
• [ ] Old clothes you do not mind spotting

Application

• [ ] A 16 to 24 oz spray bottle with SpraySticks sticks for spots, rings and streaks
• [ ] A plastic pump-up or backpack sprayer with gallon pods for bands and large areas
• [ ] Clean water for mixing
• [ ] A phone timer

Scrubbing and rinsing

• [ ] Stiff nylon brush or deck broom for concrete and pavers
• [ ] Soft brush, sponge or microfiber cloth for vinyl, paint, fiberglass and wheels
• [ ] Garden hose with an adjustable nozzle
• [ ] Bucket of plain water for quick hand and tool rinses

Mixing reference

Full mixing steps are on how it works and the pump sprayer guide.

Before you start

1. [ ] Name the stain. Orange or brown is usually rust. Black or gray is more likely mildew, oil or tire marks.
2. [ ] Find the source. Sprinkler, fertilizer, furniture, gutter hardware, rebar or a boat fitting. Write it down so you fix it afterward.
3. [ ] Check the surface. Do not use rust remover on marble, limestone, travertine, coquina or any natural stone. Skip fresh concrete that has not fully cured.
4. [ ] Read the label and the safety data sheet.
5. [ ] Pick the time. Shade or a cool, calm, overcast morning. No rain expected for a few hours.
6. [ ] Clear the area. Move cars, toys, cushions and pets. Keep children inside.
7. [ ] Put on your gear. Gloves and eye protection go on before you open the package.

Prep

1. [ ] Soak the plants. Wet grass, beds and shrubs along the work area with plain water.
2. [ ] Sweep or rinse. Remove dirt, leaves and loose debris.
3. [ ] Pre-wet the surface. Damp concrete does not pull the solution in and dry it out as fast.
4. [ ] Mix. Add water to the bottle or tank first, then the stick or pods. Let them dissolve fully, swirl or shake gently, then cap.
5. [ ] Label the bottle. Write the product name and the date on it. The color line helps: blue for marine, green for home, red for auto.

Test spot

1. [ ] Spray a small hidden area.
2. [ ] Wait the dwell time for that surface.
3. [ ] Rinse and let it dry fully.
4. [ ] Check for lightening, dulling or color change. Stop if you see any.

Apply

1. [ ] Work in sections small enough to rinse before they dry.
2. [ ] On walls and fences, spray bottom up so drips land on treated areas.
3. [ ] Start the timer when the solution touches the stain. Concrete 10 to 15 minutes. Pavers, vinyl fences and fiberglass 5 to 10. Vinyl siding 3 to 8. Car wheels 2 to 3. The dwell time guide explains each.
4. [ ] Keep it wet. Mist again if edges dry.
5. [ ] Watch the stain fade.
6. [ ] Brush with the right brush for the surface.

Rinse

1. [ ] Rinse walls and fences from the top down.
2. [ ] Push driveway rinse water away from beds and toward a drain or the street.
3. [ ] Rinse nearby plants a second time.
4. [ ] Let the surface dry, then check under good light.
5. [ ] Do a second timed pass on stains that still show, rather than a stronger mix.

Cleanup

1. [ ] Flush the sprayer, hose and wand with clean water and spray it through the nozzle.
2. [ ] Rinse brushes and cloths.
3. [ ] Wash gloves with water before you take them off, then wash your hands.
4. [ ] Use mixed solution the same day. Do not store it in an unlabeled container.
5. [ ] Store unused sticks and pods dry, sealed and out of reach of children and pets.

Never

• [ ] Never mix rust remover with bleach, chlorine or any other cleaner.
• [ ] Never let it dry on the surface.
• [ ] Never use it on natural stone.
• [ ] Never use a brass or steel sprayer, which corrodes.
• [ ] Never reuse a drink bottle for mixed solution.

If something goes wrong

If it gets in the eyes, rinse with clean water for several minutes and call Poison Control at 1-800-222-1222. If it is swallowed, call Poison Control at 1-800-222-1222 right away. If it gets on skin, rinse with plenty of water. Follow section 4 of the safety data sheet for first aid.

After the job

• [ ] Fix the source you wrote down. The prevention guide covers sprinklers, iron filters, furniture pads, gutters, fertilizer and boat fittings.
• [ ] Reorder before the next season from the shop page.

Spinach check: SpraySticks shares a compound with spinach. That does not make it food or gentle. Gloves, eye protection, keep kids and pets away, never mix with bleach, and read the SDS.

Common questions

What gear do I need to remove rust stains?

Chemical-resistant gloves, sealed eye protection, closed shoes, a spray bottle or plastic pump-up or backpack sprayer, rust remover, a garden hose with a nozzle, and a brush that suits the surface: stiff nylon for concrete, soft for vinyl, paint and fiberglass. A timer on your phone helps you stick to dwell times.

What should I do before applying rust remover?

Identify the stain and its source, check the surface is not natural stone, pick a cool shaded time, move cars and pets away, soak nearby plants with water, pre-wet the surface and test the solution on a hidden spot. Those steps prevent most of the marks people blame on the product.

What do I do after removing a rust stain?

Rinse the surface from the top down, rinse nearby plants a second time, flush the sprayer with clean water, wash your gloves before taking them off, and store leftover sticks or pods dry and out of reach of children. Then fix the source so the stain does not return.

Can I print this checklist?

Yes. Use your browser's print option on this page. The steps are written as a plain list so they print cleanly on one or two pages and can be taped inside a garage cabinet door or kept in a zip bag with your sprayer.
