The Rutland Products 16906 6-Inch Poly Chimney Cleaning Brush is really handy for cleaning metal flues. It's meant for insulated metal chimneys, stainless steel chimneys, and metal stove pipes. The poly bristles are gentler than metal ones, so they help protect your flue lining from scratches while still doing a good job of clearing out soot and creosote.

As the manufacturer describes, it has acid-resistant polypropylene bristles. These bristles make it durable and efficient for cleaning. Plus, it comes with a 1/4" NPT threaded fitting, so it works well with some Rutland rod products like their Chimney Brush Rod Kit (KRK-18) and certain Individual rods (models 10624 and 10672). This means it stays securely attached as you use it, making the whole cleaning process smoother.

From what we've found, people are quite pleased with how this poly brush does the job, especially on stainless steel chimneys because it doesn't scratch them. There's a lot of positive feedback about how the brush flexes around small obstructions, ensuring a more thorough clean.

It usually fits well with standard 6-inch stove pipes, though sometimes you might need to tweak things a bit for the perfect fit.

Some folks mentioned that the bristles can show some wear over time, but overall, many say it keeps up its efficiency and protective qualities, especially with delicate metal flues.

Hey! So, if you're thinking about using the Rutland Products 16906 6-Inch Poly Chimney Cleaning Brush on your stainless steel chimney liner, there are a few things to consider.

It's meant to fit standard 6-inch insulated stainless steel chimneys and metal stove pipes, but some folks found that the actual brush diameter can be a bit bigger than those standard pipes.

A lot of people have cleverly tackled this by using a grinder to trim the brush for a snug fit. This is particularly handy if your flue is on the smaller side or has bends that make cleaning tricky. It's a pretty common adjustment folks have shared, and it seems to work well.

One of the big pluses of this brush is that it’s tough on soot and light creosote but gentle on the liner—no scratches like you might get from metal-bristled brushes. According to the manufacturer's description, the poly bristles are acid-resistant and perfect for a good clean without damage.

It's also quite durable. A lot of people have mentioned that the bristles last long and the construction is solid, so it's reliable over time. If you run into large blockages or have a complicated chimney layout, a few folks recommend using PVC pipes or other adapters to get the brush through effectively.

Oh, and one more thing—make sure to check that your rods fit the brush well. Some people noted that the thread sizes were a bit off from what's advertised, so it’s worth double-checking to avoid any frustration.

If you're not into modifying brushes, you might want to look at the Rutland Wire Chimney Brush as another option.

It could be a better fit depending on your setup. Just make sure whatever you choose fits your needs, so your chimney stays clean and safe!

If you're thinking about using the Rutland Products 16906 6-Inch Poly Chimney Cleaning Brush to tackle creosote buildup, here's what you might find helpful. The manufacturer designed this brush for metal chimneys and stainless steel stove pipes. They say the poly bristles are tough on creosote but won't scratch the surface, which is great if you're worried about keeping your flue in good shape.

As for how well it works, our research suggests it's generally pretty effective. The bristles are stiff and acid-resistant, which helps break down stubborn creosote deposits.

But the same stiffness can make it a bit challenging to use, especially if your chimney is really sooty or has some angles. It does bend a little for tight spots, but it might struggle with dampers or odd-shaped openings, so you might need to get creative or try something else.

Another thing to keep in mind is how long the brush lasts. Some folks mentioned that while it works well at first, regular use can wear down the bristles, meaning you'll eventually need to replace it.

So, while it's cheaper than hiring a pro, if you use it a lot, you might want to think about the cost of replacements over time.

In a nutshell, if your chimney is mostly straight and you like doing the cleaning yourself, this brush could work well for you. Just remember to consider if it'll fit your setup and how long it'll last before you're buying another one.

Balancing how well it works right now with any future maintenance is key.
