Creosote reducer.

Used these for years, they do what they are designed for, dries out the oily creosote that builds up in chimney flues and liners. I clean my own chimney so I see how these help every year. Albeit the price has gone up I still buy one or two as I fire my insert all during the cold season.

Chimney Sweep in a box!

I use these creosote logs along with creosote burning powder in my fireplace all the time. I finally had my fireplace and fire chimney cleaned after 25 years. The chimney sweep said it looked as if I had just had my chimney flu cleaned the year before it was so clean. I highly recommend this product.
