Undercover System Maintenance & Cleaning

The Inside of the System
Rain will usually keep debris washed out of the ceiling. It’s still a good idea to periodically check the inside of your system’s ceiling panels.

The Outside of the System
The exposed metal ceiling surface rarely needs to be cleaned, but if it becomes dirty, spray with a water hose or a low pressure, pressure washer to dampen and remove the debris. If additional cleaning is required, use dish washing detergent and a sponge mop to remove any spots. Rinse after done and dry with towels or blow dry with a leaf blower.

Cleaning your Deck

One of the questions we get asked most often is, “What can I clean my deck with that is safe for my Undercover System?”

First and most importantly, you should never use chlorinated bleach. Chlorinated bleach is harmful to plants, not good for metals (painted and unpainted), and unsafe for the environment. Not to mention that continued use of chlorinated bleach can cause damage to fasteners, some of which attach your deck to your home. I know that it is easy to pour a little bleach in a bucket, dilute with water and proceed to bleach away, but the long term effects are not worth it.

For Natural Wood Decks
Sodium percarbonate is good choice for excellent cleaning properties, safe for plants, humans and the environment. Oxyclean is this type of product but the sodium percarbonate content is not great enough in some instances to properly clean a wooden deck. Sodium percarbonate deck cleaners are available online, or at a commercial paint supplier. Usually the big box home store such as Home Depot or Lowes do not carry this product. They typically stock deck cleaners that have Chlorinated Bleach as one of the ingredients, so be sure to always read the package ingredients.

For Synthetic Decks
We recommend Corte Clean. This product is safe for fasteners, the environment, and does a good job of cleaning decks. It has also been tested on the metals used in our system and has been proven safe.

Pressure Washing
If you use a pressure washer in conjunction with any of the above, use low pressure so that you do not raise the grain and damage your deck.
