If I remember correctly...

Ammonia is a caustic, which attacks the brass. Thus we don't use it or products like Brasso which have ammonia.

I haven't read anyone claiming Oxyclean is ok for cleaning brass. Oxidizers are known to attack metals. I know Oxyclean will attack brass because I soaked a pair of pants to long in Oxyclean and the brass stained the cloth.

Lemon juice is acidic, as is vinegar, and will clean brass; however, the brass should not be left in an acid solution to long and the solution should be washed off the brass.

I wet tumble my brass with stainless steel pins, water, Great Value dish soap and Lemishine. The Lemishine reduces the pH to help clean the brass - not that clean brass is necessarily any better for sending pistol rounds down range.
