    2 possibilities. You need fresh chemicals and/or the detergent you are
using is leaving a film, thus sabotaging your efforts. Here's what I do with
good results.
    Use mild water soluable flux. Rinse off with hot plain soapy water ONLY.
Let air dry, (cloth will also leave a film), then apply patina liberally
with a brush. Rinse off again and let dry. Then apply polish.
