What Size Chimney Brush?

Hello All! I am wanting to use the Rutland creosote remover I bought to get rid of the glaze at the top of my chimney and sweep it. I called the local home improvement stores and they only stock 3", 6", and 8" round brushes.

The inside diameter of my chimney measures 10 1/4" X 10 5/8" (see pics). I am assuming I should get the 10" X 10" brush. Is this correct or should I step up to the 11" X 11" since my chimney is slightly larger than 10" X 10"?

Also does anyone have a place they recommend to buy a brush at and get a good deal? I saw a 10" X 10" Rutland brush on Amazon for $37.

Thank you for any advice and recommendations!

I'd suggest going for an 11x11 and keeping a set of diagonal cutters handy in the event you need to trim a little to make it run through well.

Looks like you have some real creosote building up top

Thanks for the suggestion on the 11x11 brush! Trimming it with diagonal cutters sounds like a great idea!

You are right about the creosote. It's only in the top flue tile since it's the coldest part of the chimney. The creosote is the reason I bought the Rutland Creosote Remover and why I want to sweep it.

Don't trim it. Shove the 11X11 through it to get that crap out of there. Assuming you are talking about the inside measurements of the chimney. If you are cleaning from the top, take an anti-freeze jug and fill it with rocks and attach it to the bottom of the brush to pull it down.

But if it is only the top tile just shove the 11X11 up and down in the tile. But the rest of the tiles need scrubbing also.

Ok, I won't trim it. I am talking about the inside measurements of the chimney. Yes, I am going to be cleaning from the top down. Filling a jug with rocks is a great idea! I will scrub all the tiles, but as of two weeks ago there was very little build-up in any of the tiles besides the top one which has the glaze and I'm hoping the creosote remover will help soften that up.

I posted a pic of what the flue looks like from the top looking down.

get a Sooteater. Much like a weed eater, but for your flue.

Are they better or recommended over a standard brush?
