Cre-Away Pro has 50% more magnesium catalyst than regular Cre-Away and is sold in money saving bulk 25 lb pails. You'll need the Pro Applicator and your own air bottle or compressor to apply it. Regulate the pressure to about 20 psi and blast the Cre-Away Pro up the flue until it is thoroughly coated.
Cre-Away is a dry chemical that you just spray up a glazed creosote lined chimney. As your customer continues to use their fireplace Cre-Away reacts with the glaze and converts it into a brushable form of creosote (about one or two weeks).
