THE PROBLEM WITH PRESSURE TREATED WOOD. Pressure treated wood, also known as copper chromium arsenate (CCA) wood is a wood that has been placed in a vacuum where all the water and air is removed, then the wood is injected under pressure with chemicals. Hence, the name pressure treated wood. These chemicals are used to prevent moisture and insect damage. It is easily recognized by its green color, which is a result of the copper unless it has been altered by painting. But what worked in ideal laboratory conditions has fallen short of the mark in the environment.
I just picked up some warmers at the Yankee Candle store near where I live and I was told by the clerk that the full fragrance of the warmer only last 6-8 hours. You can still smell some of the scent up to 24 hours. Not enough time in my opinion considering the cost.
