Quick™ Arsenic Mini for Water, Soil, and Wood

it did what it said on the box

As described.

Had a load of old oak fence posts I was hoping to burn in my wood burner but was concerned about chrome copper arsenate treatment. Did the test first with cold water, then read the instructions and did again with the correct temp. Showed their was a good amount of inorganic arsenic in the wood, so obviously didn't burn it! Feel relieved I spent the £25 and saved potentially ingesting pollutants. Would highly recommend. Was really easy to do.
