Citralic Wood Brightener Scores (1-10)
Wood Brightening/Lightening: 8
– We used the Citralic Wood Brightener on a fence that was cleaned first with its sister product, EFC-38. The Citralic brightener lightened the wood within 5-10 minutes of application.
Cost Per Square Foot: 8
– The Citralic brightener was applied to 700 feet of fencing. One 2 pound container covered this entire area.
Ease of Application: 6
– Citralic is a powder concentrate that mixes with water at 6 oz. per gallon. The powder dissolves easily into the water and the applies well with a garden sprayer. We would have given it a higher square if it was easier to get the powder out of the container. It was slightly “sticky and hardened at the top.
– Citralic is a decent and cost-effective wood brightener.

Once the citralic is mixed, how long will the solution be viable?
40 year old redwood deck in a high uv environmet (6800 feet elevation) clear NM sunshine, very dry.
never been sealed. Can I sand it with a circular sander like a floor polisher.
What do I preserve it with and still see some of the beauty of redwood.
No need to sand, just clean and brighten for the prep. Stain with TWP stains or Armstrong Clark.
Does anyone make a deck brightener for COMPOSITE DECKING. Mine is looking really dull???????????????????????????
You cannot brighten a composite deck.
I started staining old worn barn siding on my house with a transparent stain. I do not like the color of the stain. I tried a stain stripper and power washed it. The color lightened but far from the worn light tan I started with. Is there anything I can do to removed the color (or most of it) and start over?
Did you brighten after the stripping?
We are about to stain our 1 year old new construction cedar deck that turned gray. It has never been stained before and has had very little traffic. It does not have any dirt or mold or mildew stains. Can we just brighten without cleaning with a wood cleaner?
No you need both the cleaner and the brightener for prep. You need to remove the gray and the brightener will not do that.
I cleaned and scrubbed my old cedar deck.Can I still use a brightener even though it has been days and deck is dry. How would I go about doing that, should I wet deck first and then apply brightener?
Mike, yes you can use the brightener. Wet the deck first, apply, wait 15 minutes and rinse.
Hi – I'm tackling my parents deck. We're sanding it down. Do I still need to use a cleaner, or just a brightener? It's redwood in a very dry climate.
Stefanie, you should clean and brighten after sanding to allow the stain to penetrate better into the wood.
