Yes, posting photos would be a great idea, even before you finish cleaning them up. Actually seeing the results you got so far can help us advise you. Also keep in mind that not all keris with pamor will give a high contrast effect. It will all depend on a number of factors, including what type of material was used for the pamor itself.
In regards to arsenic, i would recommend that you stay away from experimenting with other forms. What you want is arsenic trioxide for the best result. You will just be wasting time, energy and money otherwise.
Your second keris may or may not have pamor. Sometimes it can hide a bit. What are you using as a "light acid bath"?
Again, detailed photographs of both these keris will help us help you.
