Vinyl window boxes and planters do not require painting, staining or other maintenance other than cleaning.

For occasional surface cleaning, we have found that the following products work very well along with a quick rinse from your garden hose:

  • Simple Green – A good environmentally friendly cleaner
  • The Works: Basic Bathroom Cleaner with Bleach – Our production facility has been testing a number of regular household cleaners and have found that this one works surprisingly well on our products and is obviously a great value!
  • Mr. Clean Magic Eraser – Great for our White products
  • Armor All – Great to bring out the shine on our black products

For a deeper clean, we recommend the use of a high power pressure washer. As polyethylene is slightly porous, small dirt particles can become trapped over time and a power washer, used up good and close will be able to really blast the dirt away. Don't worry about damaging the planter when cleaning with the power washer. Our products do not have any type of finish so there is no risk of harming the outside.

It may take some time to remove all of the dirt and stains, but with the pressure washer on the highest setting, you'll find that the results are fantastic!


Our fiberglass window boxes and planters have been painted with an automotive grade paint to ensure many seasons of use. Occasional cleaning may be needed with gentle scrubbing with soap and water applied with a soft brush or sponge. Do not use abrasives on standard (painted) finishes.

PVC / Composite 

PVC window boxes  and planters can be easily cleaned by spraying with a high pressure hose nozzle, and following up with hot soapy water. Bleach, or cleaners with bleach can also be safely used.

Powder-Coated Finishes on Metal

Powder coated metal window boxes and powder coated galvanized liners should be cleaned with a either a soft cloth or brush, using soap and warm water. Avoid harsh chemical cleaners.


With wood window boxes, it's a good idea to treat the inside of the box or planter with a moisture protecting sealant. Before placing outdoors, it's a good idea to coat the outside of the box with an oil based stain or transparent finish. If a plastic liner is available for your wood window box, we highly recommend purchasing this as well and making sure that the liner and box properly drains.

Real Copper 

Most gardeners covet the natural patina of real copper over the years, and copper is the perfect material for garden usage. Copper supplies some nutrients to the soil over time, and it deters snails and slugs naturally. Copper can be cleaned with a mild soap and warm water, and polished if a natural patina is not desired.
