How to Remove Chalky Stuff on Resin Chairs

Updated February 12, 2018

Resin plastic chairs are popular as patio furniture because they're inexpensive, durable, easily stored and easy to clean. The original protective coating wears off over time, however, particularly if you leave the chairs sitting outside all the time in the sun, rain and snow. These chairs then tend to develop a chalky film that gets onto skin and clothing. With a little elbow grease, you can get your resin chairs looking great again.

Hose off loose dirt and dust from the chair.

Spray a generous amount of orange oil onto the chair. Allow it to soak on the chair for five minutes.

Wipe the oil from a small area where you found chalky stuff. See if the oil removed the film. If not, try scrubbing the chalky areas with a soft-bristle scrub brush.

Wipe off all the orange oil with a clean cloth. Then hose the chair off again and allow it to dry in the sunshine.

Use a bleach solution if the orange oil did not work. Add three-fourths cup bleach to a gallon of warm water.

Apply a little to the underside of the chair to make sure it does not cause discolouration. This is unlikely but may occur on chairs with bright or dark colours.

Pour the bleach solution into a plastic spray bottle. Apply a generous amount to the chair. You also can wear rubber gloves and apply it with a sponge or clean cloth. Let the solution sit on the chair for five minutes.

Wipe an area of the chair where you found chalky stuff. See if the bleach solution removed it. If not, try scrubbing the chalky areas with a soft-bristle scrub brush as you did with the orange oil.

Rinse the bleach solution from the chair with the hose and let dry in the sun.

Warning

Don't use a coarse bristle brush or any metal-based scrubbing pads, as this may scratch the resin.
