Plastic outdoor furniture is popular for its durability and low maintenance, but it still needs regular cleaning to stay vibrant and odor-free. This guide walks through effective methods, safe products, and common pitfalls to keep your furniture looking like new.
Whether you’re preparing for a season change or tackling a buildup of mold, mildew, or sunscreen residue, a simple cleaning routine can extend the life of your furniture and protect your outdoor space.
Quick Answer
Use a plastic outdoor furniture cleaner spray for general grime, scrub with a soft bristle brush, wipe with a microfiber cloth, treat mold with a mildew remover, and consider an electric pressure washer for stubborn areas. Rinse thoroughly and air-dry before use.
What You’ll Need
- Plastic outdoor furniture cleaner spray
- Soft bristle brush for plastic patio furniture
- Microfiber cloth for outdoor furniture cleaning
- Mold and mildew remover for plastic outdoor furniture
- Electric pressure washer for plastic patio furniture
Before You Start
Clear the area around the furniture to avoid splashes on plants or patios. Vacuum or brush off loose debris before washing. For delicate finishes, test cleaning products on a small, inconspicuous area first. If you’re using a pressure washer, start with a low setting and maintain a safe distance to avoid surface damage. Never use bleach on colored plastics unless the product label explicitly permits it. Allow surfaces to dry completely before use to prevent slippery spots and mold regrowth.
Step-By-Step: Cleaning Plastic Outdoor Furniture
- Remove cushions and any detachable accessories; set them aside to clean separately.
- Rinse the furniture with water to loosen dirt and debris.
- Apply plastic outdoor furniture cleaner spray evenly across all surfaces.
- Scrub gently with a soft bristle brush to lift grime without scratching the plastic.
- For mold or mildew, spray a dedicated mildew remover and allow it to sit for the recommended time.
- Rinse thoroughly with a hose or pressure washer on a low setting, keeping the nozzle at a safe distance.
- Wipe down surfaces with a microfiber cloth to remove remaining residue and improve drying speed.
- Dry completely in the sun or with a clean towel to prevent water spots and mold recurrence.
- Reassemble cushions and accessories once all parts are dry.
- Inspect seams and joints for signs of wear; re-treat any stubborn spots as needed.
- Store furniture covers handy or place pieces in a shaded area to reduce sun damage between cleanings.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Streaks after cleaning | Residue from cleaner or hard water | Re-wipe with a microfiber cloth dampened in clean water | Rinse thoroughly; use distilled water if possible |
| Scratches on color or finish | Aggressive brushing or abrasive cleaners | Switch to a softer brush and non-abrasive cleaner | Test in a hidden area first |
| Mold returns quickly | Persistent moisture or shaded area | Apply mildew remover and increase sun exposure; consider a sealant if compatible | Improve airflow and daytime drying |
| Water doesn’t rinse off easily | Sticky residues or heavy grime | Repeat cleaning cycle with milder brush strokes | Regular maintenance to prevent buildup |
Common Mistakes
- Using bleach on colored plastics, which can fade or damage the finish.
- Using a stiff brush or abrasive cleaners that scratch the surface.
- Skipping a final rinse and allowing cleaner residue to dry on surfaces.
- Cleaning in direct hot sun, which can cause faster evaporation and streaks.
Tips For Best Results
- Work in shaded areas when possible to prevent rapid drying and streaking.
- Test any cleaner on a small area to ensure colorfastness before full application.
- For tough stains, apply cleaner and let it sit for 5–10 minutes before scrubbing.
- Use a microfiber cloth to buff surfaces after rinsing for a polished finish.
- Schedule regular cleanings at the start of each season to reduce buildup.
Call A Professional
If surfaces show deep cracking, fading beyond simple cleaning, or if mold persists after repeated treatments, consider consulting a professional. Seek help promptly if there is visible damage to structural components or if the furniture contains integrated coatings or finishes that require specialized care.
