ENCLOSURE CLEANING TIPS & FAQs

How Do I Clean an Aluminum Enclosure?

Aluminum enclosures are built for durability, and keeping them clean preserves their appearance and performance over time. Whether you're dealing with smudges from installation, oxidation from weather exposure, or graffiti from vandalism, following the right cleaning methods can make all the difference. Plus, we answer common questions about panel replacement and vinyl wraps.

Remove Oxidation From Aluminum Enclosures

Corrosive conditions can lead to surface oxidation on your enclosure over time. To restore its appearance, follow these recommended cleaning methods. The first approach is ideal for mild cases, while the second is designed to address more severe oxidation. We’ve field-tested this method on our enclosures.

The Cleaning Process:

Step 1: Wash thoroughly with Dawn dish soap. You might need a brush to assist in removing heavy dirt. Next, evaluate for light or heavy oxidation and proceed with the appropriate step 2 below.

For light oxidation:
Step 2: Make sure the enclosure is dry.

Step 3: Apply a polish like MET-ALL Aluminum Polish, Mothers Mag & Aluminum Polish, White Diamond Metal Polish or similar using a microfiber cloth or power buffer/polisher. Due to enclosure size, we recommend the buffer/polisher.

Step 4: Buff evenly, then wipe clean with a microfiber towel. Follow the manufacturer’s instructions regarding how long to let the polish sit before wiping off. If oxidation is still present, repeat step 3 as many times as needed.

Step 5: Apply a metal sealant like Sharkhide Metal & Aluminum Protectant or Flitz Ceramic Sealant Spray to protect against future oxidation.

For heavy oxidation:
Step 2: Apply a commercial aluminum brightener like Aluma Brite, Sharkhide Aluminum Cleaner, Purple Power Aluminum Brightener or similar. Follow the manufacturer’s recommended dilution percentage and wear gloves, goggles and all other recommended PPE.

Step 3: Follow the manufacturer’s guidance on how to apply the aluminum brightener and how long to let the product sit. Then, rinse with water. These products will turn the enclosure a milky white color.

Step 4: If heavy oxidation is still present, repeat step 2. It might require several passes to remove oxidation. Sandpaper or a Scotch-Brite pad can assist in removing heavy oxidation or paint.

Step 5: Once a consistent milky white finish is reached, wash the enclosure with Dawn dish soap again to remove any leftover acid.

Step 6: Make sure the enclosure is dry.

Step 7: Apply a metal polish like MET-ALL Aluminum Polish, Mothers Mag & Aluminum Polish, White Diamond Metal Polish or similar using a microfiber cloth or power buffer/polisher. Due to enclosure size, we recommend the buffer/polisher.

Step 8: Buff evenly then wipe clean. If oxidation is still present, repeat step 3. It might take multiple passes.

Step 9: Apply a metal sealant like Sharkhide Metal & Aluminum Protectant or Flitz Ceramic Sealant Spray to protect against future oxidation.

Remove Fingerprints and Smudges After Installation
To safeguard the finish during shipping, every Safe-T-Cover enclosure arrives wrapped in a PVC protective film. We strongly suggest keeping this film in place until the enclosure is fully put together. Premature removal often leads to unsightly smudges and fingerprints that are difficult to remove once the surface is exposed.

If your enclosure already has marks or smears, follow these steps to restore a clean, professional appearance:

• Begin cleaning with a non-abrasive cloth and a mild soap mixed with water.
  
  
• For tougher residue, apply a small amount of automotive degreaser, but always test on an inconspicuous spot first.
  
  
• Never use harsh cleaners or abrasive scrubbing tools, as they may damage or discolor the aluminum surface.

Cleaning Graffiti
If your aluminum enclosure has been tagged, cleaning it depends on its finish.

Mill Finish (Uncoated Aluminum):
Use an aircraft-grade paint remover to lift spray paint from raw aluminum surfaces. Always wear proper safety gear and test the product in a discreet area first to ensure compatibility.

Color-Coated (Kynar^® Finish) Enclosures:
Begin with a gentle soap-and-water solution. For stubborn marks, cautiously test an aircraft paint remover on a hidden spot before full application, as aggressive cleaners may compromise the Kynar^® protective coating. 

Opting for a darker enclosure color — such as Hartford Green or Slate Grey — might deter graffiti by making the surface less appealing to vandals. Another effective solution is to use a vinyl wrap with an anti-graffiti laminate for added protection.
