Review (2/5): It's OK if you can get it delivered
I ordered this product once before. I used it to refresh our aging carpet. I doubt it is true 40v food grade, it feels too weak. But it worked for my purpose.
Since then I tried ordering it 4 times. From Amazon. Every time it ships from a local warehouse, arrives at a larger center, and gets stuck there for weeks, until I give up and request a refund.
Just bizarre.
