EFC-38 Wood Deck Cleaner Review

EFC 38 Wood Cleaner

EFC 38 Wood Cleaner

EFC-38’s unique formulation provides the strength necessary to clean gray wood, mold, mildew and heavy accumulations of grime. EFC-38 contains sodium percarbonate and additional surfactants that boost the overall effectiveness. EFC-38 was designed to clean and prep all exterior wood.  EFC-38 is safe to use and makes an excellent tool for wood preparation prior to applying a wood coating.

EFC-38 Wood Deck Cleaner Scores (1-10)

Removal of Graying, Dirt, Grime: 9

– EFC-38 is very effective at removing graying wood cells and algae. The wood surface looked 90% or better when done with the cleaning. All algae and mold were removed from the fence.

Cost Per Square Foot: 10

– Cost to clean the 1000 square foot fence was less than $.04 a foot. The powdered formula makes 5 gallons of liquid wood cleaner for 2 pounds of EFC-38

Removal of Old Stain: N/A

– EFC-38 is designed to clean wood and will strip older oil based decking stains. We did not rate it as a stripper since it is not labeled or designed to remove all wood deck stain coatings.

Ease of Application: 8

– EFC-38 mixes with water at the rate of 6-8 oz per gallon. We mixed the entire 2-pound container in 5 gallons of warm water. The EFC-38 dissolved fairly easy into the water. The product was applied with a pump up sprayer and applied to a fence. Coverage was close to 200 feet per gallon. A pressure washer was used to rinse off the gray wood and dirt.

Final Appearance of Cleaning: 9

– The fence was restored to like new condition. EFC-38 does need to be neutralized with the Citralic Wood Brightener. It is normal to neutralize wood deck cleaners and the final appearance was excellent for an application of a stain.

Overall Score for EFC-38 Wood Deck Cleaner: 9

– EFC-38 is an excellent cleaner for prepping your exterior wood, deck, or fencing. Performs as described and is very cost effective. Highly rated!
