Dirty Cornys

[Blancaster]

I came across a couple of cornys that are really nasty inside. Is there anything that I can use that will really clean these up? Sun oxy (like oxy clean free) soaks really isn't getting it :-(

bar keepers friend, PBW, and some elbow grease, let it soak for at least at least a couple hours or overnight.

Here is what John Palmer said about cleaning stainless

Cleaning Stainless Steel and Aluminum
For general cleaning, mild detergents or percarbonate-based cleaners are best for steel and aluminum. Bleach should be avoided because the high pH of a bleach solution can cause corrosion of aluminum and to a lessor degree of stainless steel.
There are oxalic acid based cleansers available at the grocery store that are very effective for cleaning stubborn stains, deposits, and rust from stainless. They also work well for copper. One example is Revere Ware Copper and Stainless Cleanser and another is Kleen King Stainless Steel Cleanser. Use according to the manufacturer's directions and rinse thoroughly with water afterwards.

Can I use a new toilet brush to scrub with, kinda hard to get my arm down in the corny.

[SkyBrew]

certainly. I got a scrubber thing from the dollar store that I use

What about cleaning the dip tubes? Is there something that is easy to use that can be purchased locally?

[SkyBrew]

I would think just soaking and running some cleaner would be good enough. if its a total loss you can get a diptube for like $5 from
