Brass/Copper Polishing in Old Temples


(2000)

We are a social organization based in the maharashtra state of India. recently we have taken up a restoration job for an old temple in a remote village. a major portion of the temple (including the idols) are of brass / copper. Due to paucity of funds we can ill afford to use expensive metal polish such as " Brasso [linked by editor to product info at Amazon] ". Can any one of you be kind enough to send us the chemical composition of such polishes so that we can be cost effective in this noble task ? You could also visit our website www.indiablessings.com which is for the religious minded people. with regards, sanjay

Ok this is an old post but if you still need the info, ketsup normal household ketsup can do it. The vinegar in it is what removes the tarnish - try that or just use straight vinegar. I hope it helps and that you see this.

Ketchup or vinegar & salt are indeed powerful brass and copper cleaners which dissolve some of the zinc, leaving the metal looking rather pink or salmon colored. They are ideal for reducing the labor element, but I would be careful about something so aggressive being used on antiquities.

You can search expired patents for the composition of brass polishes perhaps, Sanjay. Everyone feels their causes are noble, but the end does not justify the means; we certainly cannot publish a trade secret such as the composition of Brasso -- deciding for ourselves that your dream is more noble and important than the dreams of the employees and stockholders of Duraglit :-)
