Now let me see, not heard of it down here, what is CLR.

I have a cleaning job coming up, on some very delicate brass curtain rings, and have been hestitant to start, because they have fine detail on them I do not want to damage.

Is this a commercial product, that can be bought across the counter.

Thanks

What type of crud do you have on the brass rings..??If it is oil based crud ..use a strong mixture of washing soda.(Calcium Carbonate)..not Bi Carbonate...Calcium CARBONATE..
If if is scale build up such as lime or if it is oxidation of the brass itself,a mild acid such as phosphoric or muriatic acid will do the trick..Both give off fumes so be carefull..
Neither will hurt the base metal brass and only attack the deposits on the brass,if used for a short period..Usually they will clean up in a few minutes..
After acid bath rinse with a base solution such as baking soda,Sodium Bicarbonate..
Then with fresh water to clean..
To protect the shine a spray of laquer or a coating of light oil depending on the application of the rings..
If its to clean your wifes wedding ring..don't be so cheap and buy her a gold one..you won't have to keep cleaning it..
