DEFY Wood Deck Cleaner Powdered Concentrate - Cleans Decks, Fences, Siding - 2 lb

This is probably the best wood brightening product I've came across. Works great

First, this is a cleaner, not a brightener. We used to use Wolman powdered cleaner but, then, couldn’t find it. I used the liquid kind a few times but it’s quite expensive and the extra is in such a large container, you need to have adequate space to store it. I found this and decided to try it. I was very pleased and when you mix it yourself, you get more for the money and the container stores easily. It cleaned all the moldy and dark stains from our covered porch and exposed decking. I mixed it and applied with a deck sprayer. I scrubbed a few troublesome spots with a stiff brush on a broom handle. Rinsed with the garden hose. Let dry. Repeat if you think you need to. I did follow up with deck brightener and then stain. My spaces turned out beautiful!

did a great job! easy to use

Worked on our handrail and Caseibo

I tried about every possible combination of applying, rinsing, OxyClean ratios, wet, dry, pressure washer, garden hose, paint brush, roller, etc.. I have to say. Doing it EXACTLY like their 2 minute videos show, with the addition of a stiff bristle brushing, is certainly the most effective way. The wood cleaner and wood brightener really MUST be used as a combo deal. You won't get the best effect using just one. Trust me. What I learned. DO get the wood wet before using both products. You won't get a good result going on dry and thinking a "stronger, less diluted" application would be better.. Nope.. Pressure washer vs hose. Tried both. Like a hose better. The pressure washer actually doesn't put out a good volume of water, rather just high pressure. In the interest of not ripping the pores open, and actually rinsing the product, I found the hose with a spray nozzle much better. Highly recommend a bristle brush to scrub both products with. The yellow one on Amazon was too stiff. I liked the brown one https://www.amazon.com/gp/product/B004FTPT62/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Both the cleaner and the brightener turned my wood to kind of a surface jelly of fibers and dirt and without giving it a brushing, it didn't work as well. Keep things wet, don't try to do too much of an area at once. Application goes well with a sprayer. You'll be there for an eternity any other way. Make sure the brightener doesn't get in contact with any painted surfaces. It really will etch paint. DON'T use OxyClean. I tried it. I tried it in several ratios, in combination with the cleaner, solo, etc. Its little blue flecks in it are soap or something thats not desired, at least for me. The foaming action it presents is not what you want when rinsing your deck. Its a hassle. Its also half as strong (as a guess based on sample areas) so you use a bunch more and still don't get as good of a result. I'm using mine on Kiln dried Cedar decking and header timbers. About 1600 square feet.

Great product however make sure you use warm water and then stir it until it’s clear again and not milky looking and it will spray perfectly.

Worked as advertised. I would definitely use this product again.

Tried this on my old teak outdoor furniture and it just didn’t do the job. It didn’t clean or brighten the wood the way I hoped. The teak still looked the same afterward. I didn’t test it on any other types of wood, so maybe it works better elsewhere, but for teak restoration it wasn’t the result I needed.
