Question from Sunnyside
Are there any problems, or cautions, regarding power washing of pressure treated wood (to get rid of green mold and dirt) that does contain arsenic? Any recommendations on product to use? Also, does anyone have any suggestions on a product (paint, etc.) that could be used to seal the wood by an individual who has sensitivities to some chemicals?
Debra’s Answer
Don’t power wash. According to The Pressure Treated Wood Information Site
“power washing which can break the bond with the metals and cause metal contamination”.
