What brightener is better and brighter for brass polishing

Copper products after processing out or placed for a period of time, the surface will appear oxidation, discolouration, darkening. Not only, affect the appearance of copper products workpiece, but also accelerate the corrosion rate of copper products, shorten the use of time. So, this situation we should how to improve the copper surface gloss to let it back to bright as new?
Copper polishing solution T302, is the use of S oxygen water oxidation for polishing additives for the environmental technology and the development of a new type of copper chrome-free ammonia-free polishing agent for all pure copper, brass and other copper alloys chemical polishing. It can make all kinds of copper instantly obtain the effect of bright as a mirror. This product has low acidity and special hydrogen peroxide stabiliser, which can effectively control the rapid decomposition of hydrogen peroxide in the environment below 80℃. Thus the stability of polishing quality.
Slotting ratio and conditions of use
Suggestion: Dilute T302 with water according to 1:2~3 (pure water is preferred).
Equipment Requirements:Plastic containers can be used as polishing baths, plastic containers should be made of PVC or PP materials, the size of which depends on the production capacity. If the production volume is large, the tank needs to do constant temperature (cooling) design, to ensure that the production process solution temperature stability, uniformity (due to the production process, copper and hydrogen peroxide reaction will be exothermic and caused by the heating), for the service life of the potion using temperature should not exceed 60 ℃.
Usage: Heat the configured polishing solution to 40~50℃, put the cleaned copper parts in the polishing solution for about 1~3 minutes, and then take it out and wash it with water. At this time, the surface of the copper has formed a brown transparent oxide film. Then put the copper parts into the film removing solution T402 immersed in about 3-8 seconds can be the surface of the brownish-yellow film back to the net and present a bright surface.
