Quick answer

How to stop patio furniture from rusting: sand or brush the rust back to bare metal, prime and repaint the chips with rust-inhibiting paint, then keep the furniture dry. A waterproof, vented cover stops the rain and dew that make rust come back, and it is the easy part of the fix to keep up.

Free fix vs. permanent fix

Free fix · 2 hours plus drying

Sand, prime and repaint the chips

  • Brush or sand rust back to bare metal
  • Wipe it clean and let it dry
  • Prime, then paint two thin coats
  • Move it under cover when you can

How long it lasts: A season or two if the furniture stays outside and wet. Rain finds the next chip.

A waterproof, vented patio furniture cover

Rust needs water and air on bare metal. Paint seals the chips you can see, but wet weather finds new ones. A cover stops the water. Look for vents so the metal can still dry out underneath.

What to get: Waterproof, vented patio furniture cover

How long it lasts: Often several seasons, as long as the cover holds up. It keeps rain and dew off, so chips stop rusting.

Why it happens

1

Chipped or scratched paint

Steel and iron rust only where bare metal meets water. A chip from a dropped cup or a scraped leg is enough to start it.

2

Water that sits

Rain pooling in seat frames, feet standing on wet ground and morning dew all keep metal wet. Water trapped in hollow legs rusts them from the inside.

3

Salt air and humidity

Near the coast or in damp climates, metal stays wet longer. Salt speeds rust up.

4

Thin factory coatings

Low-cost paint and powder coat can be thin. They wear through at the edges and joints first.

Do these in order, starting with the simplest.

  1. Check that it really is rust

    Hold a magnet to the frame. If it sticks, it is steel or iron and will rust. If it does not, it is aluminum, which does not rust but can turn chalky white. Scrub that with soapy water and a soft brush.

  2. Brush or sand the rust to bare metal

    Tool used: Wire brush or sandpaper

    Wear gloves. Work the wire brush or coarse sandpaper over rust and loose paint until you see shiny metal and a firm edge of paint. Wipe the dust off with a damp cloth and let the metal dry fully.

  3. Prime and repaint in thin coats

    Tool used: Rust-inhibiting metal spray paint

    Use a rust-inhibiting primer or a spray paint made for outdoor metal. Spray two or three thin coats and follow the can's dry times and temperature range. Paint on a dry day.

  4. Wax the frame

    Tool used: Paste wax

    Once the paint has cured, wipe on a thin coat of paste wax. It helps water bead off and run away.

  5. Cover it and lift the feet

    Tool used: Waterproof vented patio furniture cover

    Dry the furniture, then use a vented cover that reaches the ground or ties down. Do not drag a plastic tarp over wet furniture. Set feet on pavers or pads so they do not stand in puddles.

When free fixes aren't enough

If rust has eaten through a leg, left flakes of metal or made the frame flex, paint will not restore strength, so replace the piece. If you repaint and rust comes back within a season, water is reaching bare metal faster than you can touch up. That is where a cover earns its price: it keeps the furniture dry between uses, so the paint you applied stays sealed.

Waterproof, vented patio furniture cover

Fixes: rain, dew and snow soaking bare metal

Look for: Sized for your set, so check the length, width and height; Waterproof fabric with sealed or taped seams; Vents so moisture can escape; Straps, buckles or a drawstring so wind cannot lift it.

Who it's for
Anyone with steel or wrought-iron furniture that stays outdoors all year.
Honest downside
Your furniture is aluminum or resin and does not rust. Also skip a cover that does not fit, since wind will flap it loose.

How we picked: How we picked: this page is based on rust-removal and metal-care guides, instructions from paint and cover makers, and what owners report in reviews of patio furniture covers. We do not test products by hand.

Which furniture will rust?

  • Steel and wrought iron: rust when the coating breaks. A magnet sticks to them.
  • Aluminum: does not rust, but can turn chalky white.
  • Powder-coated steel: rust starts where the coating chips.
  • Stainless steel: resists rust, but can show surface spots near salt water.

What to skip

Painting over loose rust, and tight tarps

Paint on top of flaking rust peels away with it and hides the problem while rust spreads underneath. Remove the loose rust first. Also skip a tarp wrapped tight with no vents. It traps moisture against the frame.

Frequently asked questions

Can you stop rust that is already on patio furniture?
You can stop it from spreading if you remove the loose rust, prime and repaint. A rust-converting primer can treat light surface rust, but heavy rust must be brushed off first. Follow the can.
Does aluminum patio furniture rust?
No. Aluminum has no iron, so it does not rust. It can corrode to a white chalky film, especially in salt air. Scrub it with soapy water and a soft brush.
Is a cover better than storing patio furniture indoors?
Indoors is best for winter if you have room. A cover is the next best choice. A vented cover keeps most rain off and lets damp air out.
What paint should I use on rusty patio furniture?
Use a primer and paint made for outdoor metal and labeled rust-preventing. Spray thin coats and let each dry. One thick coat tends to drip and peel.
