Cutek Extreme Wood Protection Oil can be used on a brand new deck without pre-cleaning. But, if you are using it on an existing deck, fence, or wood structure, you first have to bring it back to its original condition. For this we recommend Cutek’s QuickClean or Cutek’s Wood Reviver. “Cutek ProClean Stain Remover [now called CUTEK Wood Reviver] is a professional wood restoration agent which cleans, brightens and restores wood… surfaces to the appearance of new wood. Use when wood is significantly grey and weathered, or to remove stubborn stains such as tannin stains, resin stains, fungal & algae stains, green CCA stains, oil and grease stains.”*
If only a gentler clean is needed, then CUTEK QuickClean should be enough.
