Cleaning Your FRP CleanSeam™ Panels Doesn’t Have To Be A Dirty Job

When you choose high-quality fiber-reinforced plastic (FRP) CleanSeam™ insulated metal panels for your construction project, you’ve made a smart investment in keeping your building looking good for the long term. They’re durable, energy-efficient, and a great choice for industries such as food processing, commissaries, pharmaceutical manufacturing, clean rooms, and data centers – plus, they’re created with easy maintenance in mind.

Inside, the FRP CleanSeam panel features a traditional, insulated metal panel with a Class 1 foam core for superior R-values. But outside, your room or area is enhanced with a smooth, virtually seamless wall that provides an attractive, modern look. Because the panels connect with double-jointed edges, the resulting smoother surface keeps moisture and dirt out, and hygiene at a maximum.

For further protection, the advanced FRP CleanSeam sealant can be applied to seal the joint and act as an extra barrier against moisture and bacteria. Using the CleanSeam panel with factory-applied fiberglass reinforced plastic and the CleanSeam sealant together creates a durable, cleanable, continuous smooth wall surface, eliminating unnecessary time and labor for sanitation. Additionally, the factory-applied FRP provides superior panel surface for maintaining durability and cleanliness. The revolutionized caulking system creates a permanent, unbroken seal that can take the pressure without needing constant attention.

And while the panels are designed to keep dirt and other unwanted elements out – they are also safe to clean as frequently as needed. They won’t rust, peel, or allow water to penetrate.

While routine cleaning of your metal panels is a fairly simple process, there are few things you want to be sure not to do:

  • Do not use scouring powders
  • Do not use wire brushes, steel wool, or any abrasive cleaning or scrubbing tool
  • Do not scrub any area of a metal panel for an extended amount of time
  • Do not use any cleaning solution without testing a small area of the panel first

Cleaning Techniques and Solutions

Start by wiping your panels with plain water and a soft sponge or cloth. A preliminary wipe-down will help loosen dust and dirt to ensure you get the maximum results from your cleaning efforts.

For buildings that house cleanrooms and data centers, using a mist spray and wiping by hand is effective. For food processing interiors, using a hose to spray down may be necessary for best results.

For basic cleaning, a mixture of hot water and a mild detergent or household cleaner is effective. Commonly used food industry sanitation processes can also be used on CleanSeam, including high-pressure hot water and cleaners including sodium hypochlorite. Never use abrasive cleaners and refer to the Metl-Span CleanSeam maintenance guide for details.

Using a soft cloth or soft-bristle brush, apply the cleaning solution to one section at a time, working from top to bottom, then follow with a clean water rinse. For build-up of substances that are not water-soluble, such as oil residues or other difficult substances, use mineral spirits applied with a clean cloth and thoroughly rinse with clean water.

Once you have completed the cleaning and rinsing of all panels, it’s helpful to inspect for any excessively dirty areas that may need a second round of cleaning.

Proactive Is Protective

One of the biggest advantages of building with metal construction materials is the lower maintenance. Cleaning your metal panels can be a simple task that keeps them looking new – and it doesn’t have to be a difficult, time-consuming chore. Be proactive and plan to clean your panels at regular intervals, rather than waiting until the job becomes more challenging.
