Gather these simple supplies before you begin:
- 2 cups warm water
- 1 tablespoon dish soap
- 1 tablespoon baking soda
- 1 tablespoon white vinegar
- Soft scrub brush or sponge
- Bucket or bowl
- Garden hose or clean water
- Microfiber towel (optional)
Step 1: Prepare the Cleaning Solution
In a bucket or large bowl, combine:
- 2 cups warm water
- 1 tablespoon dish soap
- 1 tablespoon baking soda
- 1 tablespoon white vinegar
Stir everything together until well mixed.
The solution will fizz briefly because the baking soda reacts with the vinegar. Once the bubbling settles, it’s ready to use.
Step 2: Remove Loose Dirt
Before scrubbing, rinse the chair with a garden hose or wipe it down with a damp cloth.
Removing loose dirt first prevents scratching the plastic while cleaning.
Step 3: Apply the Cleaner
Dip a soft scrub brush or sponge into the cleaning mixture.
Scrub the entire chair using circular motions.
Pay extra attention to:
- Armrests
- Seat
- Backrest
- Legs
- Corners
- Grooves and textured surfaces
These areas usually collect the most dirt.
Step 4: Let It Sit
Allow the cleaning solution to remain on the chair for 5–10 minutes.
This gives the ingredients time to break down grease, mildew, and stubborn stains.
Avoid letting the solution dry completely in direct sunlight.
Step 5: Scrub Again
After the waiting period, scrub the chair once more.
Focus on any remaining stains until they begin to disappear.
For textured plastic, use a brush with soft to medium bristles to reach into the grooves.
Step 6: Rinse Thoroughly
Use a garden hose or clean water to rinse away:
- Soap residue
- Dirt
- Baking soda
- Vinegar
Continue rinsing until the water runs clear.
Step 7: Let It Air Dry
Place the chair in a sunny, well-ventilated area.
Allow it to air dry completely before using or stacking it.
You can also dry it with a microfiber towel to prevent water spots.
Tips for Stubborn Stains
If your chair still has tough discoloration:
- Repeat the cleaning process one more time.
- Scrub stained areas a little longer.
- Use a soft-bristle brush instead of a sponge for textured surfaces.
- Clean chairs regularly to prevent heavy buildup.
Helpful Maintenance Tips
To keep your plastic chairs looking clean all season:
- Wash them every few weeks during outdoor use.
- Store them indoors or cover them during winter.
- Wipe spills immediately.
- Avoid abrasive steel wool or harsh scouring pads that can scratch the plastic.
- Rinse off pollen, dust, and bird droppings before they become difficult to remove.
