ACS Anti-Creo-Soot Liquid 32 Ounce

Let me start off by saying, I don't think I've ever written an Amazon review. However, this product really surprised me and worked so well that I want to share my experience to hopefully help and save someone else money.I am incredibly pleased by this spray and highly recommend to anyone who burns firewood. I had a "third-degree" creosote problem where the creosote was not sweep able - it was thin tar like layer (first picture). I figured I was going to have to get professionals to take care of it, but decided to give this product a try.Following the instructions, I sprayed this product on almost every fire I had from January 2023- March 2023. I used the entire spray bottle in this time period. When I checked my chimney in the Spring, I couldn't believe how well this stuff worked. It caused the creosote to harden and start to crumble off of the terracotta. I can't tell you how soon it started to work, but my build up was pretty bad so I assume it took at least 20-30 fires to get it to a sweepable condition.I finally got around to sweeping it this October 2023 (the chimney sat all summer unused and unswept). It swept pretty darn well for the condition it was in last January. It's not perfect, there is still some areas of a creosote coating at the top ~8' of my chimney, which is what the 2nd picture shows. I am going to get a second bottle of this and will continue to spray on every fire and try to sweep in a month after burning fires.Even once I get my chimney completely clean, I most certainly plan to continue to use this spray as a preventative. I can't recommend this stuff enough. I think it will really help keeping the chimney clean and safe.

I can tell its working because, as soon as I spray a few shots into a hot flue, I can hear material falling in the chimney. I can immediately feel more heat off of my wood stove because creosote is a far better insulator than carbon. The chemical conversion is immediate and the results are obvious. I have a heat reclaimer that I thought I had to replace because I could no longer move the creosote clearing part. As soon as I sprayed this stuff into the stove, I was able to clear the reclaimer. This product is essential for anyone with a wood stove or fireplace.

My father has seen incredible results with this product and I bought it from his recommendation. First use I lost more dripping from the sprayer than actually spraying into the fire box. Going to try a different sprayer.Update: After a few uses the sprayer isn’t as leaky as it was the first use. Still a few drops. I will continue to use the provided sprayer. I’m also spraying before the fire is too hot to be close enough to hold the sprayer inside the fire box so drops fall in the firebox and not the floor.

It's rare that I will take time to write a review here....but this is worth the money for the problem it has solved so far. I have an older woodstove that doesn't have a catalytic burner and use the relatively low-quality firewood thats available locally. I run the stove almost every day during the winter. I've already had a chimney fire that fortunately didnt do any damage, but makes me a little neurotic. I clean the flu frequently, sometimes every couple of weeks for peace of mind. My biggest concern is the gradually increasing amount of Type 3 creosote which is the hard glassy type that clings to the walls...and isn't easily removed with the poly brush which is required for use in the stainless steel triple wall section that goes through the roof. A stiff wire brush would probably solve my problem in the short term but it causes scratches in the liner that creates a place for more and more creosote to accumulate.I've used this product heavily for the past week...as in almost the whole 32 oz bottle. Expensive, yes. I've cleaned the flu enough times that I can kind of "feel" how dirty it is based on resistance and how the brush sounds (crunchy vs smooth) as it passes along the sidewalls. It definitely "felt" cleaner today and the real evidence was that there was far less creosote than expected in the firebox when I was done. I also noticed when looking up at the chimney cap that the vent holes weren't as clogged as they usually are at this point (and which is usually indicated by a small amount of smoke backing into the house when I open the door to the firebox.) I haven't been able to get up on the roof for a close-up inspection yet.I will say that if you have existing stubborn creosote then plan to use a lot more than the maintenance dose of 10 sprays every third fire until you have been using for awhile. The directions also say this. I start a relatively small but hot fire and then DOUSE the wood with this stuff and spray up into the flu itself. I mean 40-50 sprays, and let it flame back up. This is the best time because the flu gases arent moving as fast and can swirl and stick to the sidewalls to do their work. And then I would do the same again after the fire had been cooking for awhile...probably less effective.Also, clean your chimney well before using this so it isn't wasted...the surface crust has to be removed so the stubborn stuff is exposed and the vapors can soak in.

Works great. Going to buy more

Doesn't clean very well,leaves swirl smear from wiping.On heavier sooted glass need to apply more than 2 times
