DeckWise® Deck Cleaner Parts 1/A & 2/B
Wood traps dirt, pollen and grime and when using exotic hardwood lumber it pays to maintain it. The Part 1 cleaner eliminates mildew, dirt, mold and stubborn stains. It also removes graying and reconditions Ipe, Tigerwood, Cumaru, Redwood, Cedar decking and outdoor wooden furniture or hardwood siding. Rejuvenate the rich color and distinct wood grain patterns and restore the all-natural lavish color before properly refinishing. The concentrated powders are developed to clean external hardwood decks, fences, hardwood siding, wood railings, benches, chairs and other outside wooden objects.
The Cleaner Part 1 is an oxygen rich wood cleaner that contains no bleach. When you follow the instructions on the Deck and Wood Cleaner label, the product is safe to use and will not damage wood, vegetation or lawn and is bio-degradable. Do not use a power washer on hardwood lumber which could leave scars and raise the wood grain. Always scrub with a non-metal brush. Wood cleansers can easily increase the pH level of lumber. Always follow cleaning with the DeckWise® Deck and Wood Brightener Part 2.
DeckWise® Deck Cleaner & Brightener Part 2 restores the pH level back a neutral state. It also removes tough rust and tannin stains caused by leaves, as well as mold and fungi stains while brightening the hardwood for finishing. It is recommended for use on most species of hardwood, including Redwood, Ipe, Cedar, Cumaru, Tigerwood and thermally modified softwoods. Brighten and restore the all-natural allure of outdoor wooden decking and rainscreen wood siding, outdoor furniture, hardwood fences, wood railings and steps. The goal of our product is to prepare the wood after cleaning and to eliminate the caustic affect from the Cleaner. The Brightener Part 2 is an oxygen-rich formula that contains the ingredient Oxalic Acid. It is a pH neutralizer and will re-establish the pH level to the wood.
Once the wood pH is neutral, the wood is ready to accept your choice of stain or oil finish more evenly and will certainly improve the beauty of the wood. We recommend our Ipe Oil Hardwood Oil Finish. The brightener also prepares new wood by stripping mill glaze. It can be used to eliminate rusty areas on concrete, brick and masonry as well. The Brightener Part 2 is a powder concentrate offered in 16 oz. jars. Mix at a 4:1 ratio with warm water. For tougher jobs, you may require several applications or a more powerful mixture.

Natural Thermal Enhancement of Hardwood & Softwood
Thermory® elevates the performance of select hardwoods using a precise thermal process relying only on heat and steam, without chemicals, to enhance durability, dimensional stability, and visual richness.
How It Works
Thermory’s controlled, two-stage method begins by reducing the wood’s moisture to nearly zero over an extended, closely monitored heating cycle. Once dehydrated, we elevate the temperature to species-specific thresholds and then carefully cool and mist the boards.
This complete internal transformation, not just surface-level, yields timber that performs with confidence in both interior and exterior architectural applications.
Thermory® is the clear choice for long-lasting, beautiful biophilic driven design.
