Before and After - I decided to clean my regulator!

[Frozen]

I purchased a new regulator off ebay and when I got it I could tell it was brand new but that it had been sitting in a warehouse for many years. I used a product from my local hardware store (Brasso) and I think it did an excellent job (despite the smell).

After:

I wanted to remove the cga320 stem but I was unable to twist it off. I think I even ended up stripping the end of the stem. How does everyone else remove it?

Some regulators have left-hand threads on the high pressure side. Can't tell from the photos. Looks like it has thread-locker on it too. Hit it with a heat gun to loosen the thread locker.

Also, doesn't look like it was sitting in a warehouse for many years. The body is stamped "6 13" and there's a testing date sticker on the back of the low-pressure gauge that says "6-4-13."

Wow... I feel so dumb. I know that the high pressure side was left handed, I just never made the connection that I have to turn it the other way! Also, to add to that I didn't even read the production date. Who knows why the brass was discolored.
