Restoring a 150 year old Russian Samovar. It was polished many times in the past using abrasives that eventually had rendered the maker and proof stampings nearly invisible. It was uniformly tarnished to a darker color and I didn't want to use more abrasive compounds. This stuff sounded far too good to be true, but...WOW! It works exactly as it claims. No vinegar stench, no scrubbing, no real effort. I tried several pieces of different varieties of brass and only one item, which may be bronze or some odd alloy of brass, failed to work. It was a wing-nut wrench for an antique transit tripod, not related to the Samovar. I have several old brass items at various stages of restoration, and brass comes in many different varieties. The samovar was made of yellow and pink brass. Who knows how or where the Russians made those beutiful things, but over the century of surviving wars and many owners, one never can be sure what is or is not orginal. This product works on all real brass from all ages. What a relief to find such a product, at last.

My brass items were extremely tarnished and required two treatments to get them fully cleaned. But patience and some elbow grease paid off and all items shine beautifully.

While it didn't clean quite as easily as described, it is the only thing I found to clean my brass doorknobs and hardware. Still requires steel wool and a lot of elbow grease but really loosened the grime for cleaning my brass. Must better than steel wool alone!

This worked like a charm. I didn't have any place to use as much water as it called for, so I just filled up my kitchen sink and used that. All my copper and brass pieces were clean in minutes.

All of my brass is brite
