I have used Wrights Brass polish every day for over a decade...it is simply the best and easiest...don't even bother with the others.
I have always used Wright's brass polish. I used to buy it at the grocery stores or drug stores, but for some reason no one is selling the brass cleaner. Next to all the brass cleaners out there I find that Wright's makes it easier for polishing brass. I am happy with this product.
