Keeping brass shiny
After polishing my brass-How do I keep the shine? I tried a clear spray. I did not like the finish-dull.Phyllis Lubiniecki

General purpose lacquers must fit many needs and are not optimized toward protecting brass from tarnish in an indoor environment while retaining the luster. Buy a special purpose lacquer, and consider thinning it. G.J.Nikolas offers such specialty lacquers.

Now I am new to this sort of thing so please consider the safety aspect of anything that follows - and I hope someone tries to answer my problem as quickly as I am attempting to help you (go on say it "sarkey Sod") but mine is listed as
letter 15079. now whether the following will be of help I am not sure - but it comes from my Machinery's Handbook =>
And the 2nd part is titled "To produce a Rich Gold Colour". Brass can be given a rich gold colour by boiling it in a solution composed of two parts by weight, of Saltpeter, one part common salt, one part Alum, twenty four parts water and one part hydrochloric acid. Another method is to apply a mixture of three parts Alum, six parts Saltpeter, three parts Sulphate of Zinc, and three parts common salt. After applying this mixture the work is heated over a hot plate until it becomes black, after which it is washed with water, rubbed with vinegar, and again washed and dried.
Perhaps then your lacquer would not affect the shine so much - well at least I tried.Nigel J Dyne
