Outdoor plastic storage cabinets are a great way to keep your patio, porch or deck organized. However, being outside means they are exposed to dirt, grime, mold, mildew and other elements. Regular cleaning is essential to keep them looking their best and lasting a long time. Here is a comprehensive guide on how to clean outdoor plastic storage cabinets.
Supplies Needed
- Mild dish soap or detergent
- Water
- Soft cloths or sponges
- Old toothbrush or other small scrub brush
- All-purpose cleaner or plastic cleaner
- Bleach (optional)
- Protective gloves
- Eye protection
Steps for Cleaning
Remove Items and Sweep Out Debris
The first step is to remove everything from inside the cabinets so you can access all the surfaces. Sweep out any loose dirt, leaves, spiderwebs or other debris with a broom.
Mix Soap and Water Solution
In a bucket or large bowl, mix a few drops of mild dish detergent with warm water. You can also use a plastic-specific cleaner if you have one available.
Wash With Soap and Water
Dip your cloth or soft sponge in the soap solution and wipe down all interior and exterior surfaces. Get into crevices and corners. This will lift off most dirt and grime.
Scrub With Bristle Brush
For tougher stains or buildup, use an old toothbrush, bottle brush or other small scrub brush to gently scrub affected areas. Apply more soap as needed. This helps break up stuck-on gunk.
Rinse Thoroughly
Wipe all surfaces with a clean, wet cloth to rinse away any soap residue. You may need to repeat rinsing several times to remove all suds.
Disinfect (Optional)
For extra cleaning power, you can mix 1/2 cup bleach into 1 gallon of water. Wipe cabinets with this solution and let sit 5-10 minutes before rinsing. This helps kill mold and mildew.
Remove Exterior Stains
Use a plastic-safe all-purpose cleaner and scrub brush to remove tougher exterior stains. Spray on and let sit before scrubbing. Be careful not to damage the plastic finish.
Dry Completely
Make sure to dry all parts of the cabinets fully before replacing items. Use a towel or let air dry. Moisture left inside can allow mold to grow back quickly.
Maintain Often
Aim to deep clean outdoor plastic storage cabinets every 2-3 months. Quick wipedowns after use helps prevent major buildup over time.
Tips for Best Results
- Clean on a mild, dry day if possible. Direct sun can dry soap too fast.
- Test cleaners on an inconspicuous spot first to check for discoloration.
- Avoid harsh chemicals like acetone, scouring pads or wire brushes.
- Get into corners and crevices for a thorough clean.
- Let cabinets dry fully before closing up to discourage mildew.
- Reseal any cracked caulk to prevent water intrusion.
- Keep cabinets under cover to limit sun damage and weathering.
Common Questions
What is the best way to remove mildew from outdoor cabinets?
Mixing 1/2 cup bleach into 1 gallon of water makes an effective mildew remover. Spray or wipe on and let sit 5-10 minutes before rinsing thoroughly. Wear gloves when using bleach.
How can I make plastic cabinets shine again?
Use a plastic polish or restorer after cleaning to renew shine and luster. Apply with a soft cloth and buff to create a protective finish.
What should I avoid using on outdoor plastic?
Avoid harsh chemicals like acetone or mineral spirits as they can damage and fade plastic. Scouring pads, steel wool and stiff bristle brushes can also scratch.
How often should outdoor cabinets be deep cleaned?
Aim to do a thorough clean every 2-3 months. Quick wipedowns after use can help maintain tidiness in between deeper cleanings.
Can I use a pressure washer to clean outdoor cabinets?
It’s best to clean by hand. Pressure washers can damage plastic and push water into crevices causing leaks or mildew. Use a mild soap, soft brush and gentle scrubbing instead.

By using mild soap and water, scrub brushes and proper drying, you can remove dirt, grime and mildew buildup. Take time every few months to keep your outdoor cabinets like new.
