I'm building garden beds and I got a packet of this stuff:
https://eartheasy.com/eco-wood-treatment/#spec-id
which is said to be a non-toxic, zero-VOC wood preservative. I used it this weekend and will know if a few years if it's any good at preserving wood. But one thing I know is that it's expensive, $20-$30 for a two ounce packet, which makes a gallon of wash. This is comparable to other non-toxic wood treatments, but still really costly.
I asked the manufacturer what's in it and they said "a combination of minerals" and that "it's been used over in Europe for many years as a non toxic wood preservative". They sent me the MSDS, which has more information, but not the actual ingredients, which are a "trade secret". The pH is 3.7.
Can anyone make a guess what this stuff is?
