Chemicals are in the sky, and in the house.

We’re talking about the big money in the world of petrochemical manufacturing.

In addition to the most powerful industrial chemicals, we’ve also got the most diverse, and the most difficult to spot, chemicals to choose from.

With this in mind, we decided to put together a list of the top-selling petro chemicals, based on what we know about their chemistry.

We know they contain things like chlorine, arsenic, mercury, and more.

But what we don’t know is where those chemicals come from, and how we can use them in the home.

We found some interesting information in our research that might shed some light on how petro companies are marketing chemicals to pet owners.
