Spray on oven cleaner and some elbow grease. I didn't have an over to throw it in but I let it soak a couple times and scrubbed it with a wire brush. I think if you have an old oven to put it in, it would probably look good as new. After using the oven cleaner, I used some automotive aluminum polish to shine it up a little and it looked pretty good.

DRANO, just don't leave it in there for too long.


I once forgot a pipe in that was soaked in Drano for 4 weeks, not much left

Try anti-freeze. It works great. Just soak the pipe and rinse if off. Keep your pets away from this because it is poison if they drink it.

Be aware though that Drano and Oven cleaner will remove any anodizing on the pipe if it has it.

Default pipe cleaning

The best way I've found is that after each run if possible use some fuel to clean the pipe preventing varnish and tire buildup. That being said I use CARB and CHOKE cleaner sold in the 1 galon tin, it stinks so just throw the pipes in and leave it,prefferebly outside a couple days.

Use new anti-freeze every time or it will stain the pipe. I made that mistake once.

I have also heard simple green for a day or so in a crock pot works too.

We have the secret up here in Norcal. It's called Carbon-Off. It is sold in Smart and Final stores. You spray it on and leave it sit about 30 minutes. Wash it off and it looks brand new again.

Thanks for all the suggestions.

I ended up trying the Carbon-Off from Smart and Final and this stuff really works. I spayed it on and let it sit for 15 min and rinsed with water and it pulled the carbon build up right off.

For the stubborn areas, it says use a scotch pad.
