Exterior Cleaning Frequently Asked Questions
How often do I have to do maintenance on my Exterior Oil deck?
Most decks need a light maintenance coat once a year, but it depends on exposure to direct sunlight, shade, or heavy use. Darker oil colors provide stronger UV protection, so they may last longer between treatments.
What materials/surfaces can WOCA Exterior Cleaner be used on?

Does Exterior Cleaner remove green growth?
Yes. WOCA Exterior Cleaner removes dirt, mold, stains, and green growth from compatible exterior surfaces. When properly diluted, it can also be used around plants. For more outdoor cleaning and maintenance advice, visit the Outdoor Wood and Deck Care resource center.
Is Exterior Cleaner safe to use around plants?
Yes. WOCA Exterior Cleaner is a plant-safe outdoor surface cleaner when properly diluted. Follow the application and dilution instructions when working near flowers, shrubs, lawns, or surrounding vegetation.
Do I need to apply exterior oil after using the cleaner?
Apply WOCA Exterior Wood Oil after cleaning when the wood needs renewed protection from outdoor exposure. Cleaning removes surface buildup, while oil provides the protective finish.
Do I need to clean my deck with Exterior Cleaner before applying Exterior Oil?
For best results, clean new wood to allow for maximum oil absorption. Older or weathered wood should be thoroughly cleaned with WOCA Exterior Cleaner and allowed to dry before applying Exterior Wood Oil. Cleaning removes buildup that could interfere with an even oil application.
If I treat my teak furniture will it lose its silver-gray appearance?
Yes. Applying oil will enhance the natural color and slightly darken the teak. If you prefer the natural silver-grey look of weathered teak, choose Exterior Oil in Silver or Grey.
