The material in decking is recycled soda bottles blended with cellulose ie., your 50% 50% cotton or rayon T-shirt.
So, we provide a two-step approach and deal with the cleaning of each substrate to ensure each of the two materials are correctly addressed by exposing each of the materials at separate times to the right combination of chemicals followed by a power washing. To clean it correctly, we address the outdoor pollutants followed by a cellulosic brightener!
Your wood has been exposed to all the elements (same as your automobile) from the time Package A was completed. Pollen (the green powder that sits on your car in May), Bio Pollutants ie., acid rain, bird droppings, pet droppings, dust, building dust from all the sawing from the neighbor's restoration, and maybe even ice-melting pellets have come in contact with your wood. Couple this with rain, humidity, exposure to temperatures anywhere from 0 F. to 100 F., snow, ice, wet leaves when let to sit anywhere from six months or longer, will dull the finish, but not lessen the protection unless the wood was abused and has deep gashes.
The oils which are deeply seated into the pores of the wood are protecting it against moisture, mildew and algae, and UV damage. Package A goes to great lengths to make certain that your wood is protected. However, this doesn't preclude the wood's surface from accepting dirt or dulling the appearances.
Package B is the solution for you. Package B is a combination of wood cleaner and wood brightener. The first order of business is to remove all the stubborn bio-pollutants, which sit on the surface and camouflage the way the eye sees the wood. Secondly, most woods contain tannin acid. Tannin is a natural by-product of wood and can discolor it, by making it darker. Translucent stains although allow all the beauty and character of the wood to shine through to the surface, it doesn't block tannin acids as would a semi-solid or opaque stain. Therefore, a wood brightener will brighten the wood by removing the tannin bleed. This process is about 35% to 40% of the cost of Package A and should be part of the maintenance required in professionally managing the upkeep of a beautiful deck. This process will not bring back the original color as none of the major providers of deck stains guarantee color nor will it remove the protective oils embedded in the wood, but will, however, make it brighter and cleaner. You can expect with wood a retracement of 20–30% of the color.
It's simple. Like the weekly dusting or polishing of your home's interior wood furniture or floors or weekly car wash, it's best to hose down your deck regularly, using a high-pressure hose. We recommend a weekly hosing beginning in early April through the end of September. Also, be sure to remove leaves with a leaf blower (not rake!) before they get wet. Siding should be washed down every four to five weeks. Your deck and wood siding should be professionally washed annually using a combination of our professional-grade cleaning agents.
