The LemiShine I got from Walmart came in a baggie-like container. Here's a link to the same stuff in a regular container; read the reviews:

I just dissolve some in water and place it around the base of the faucets and use a sponge to apply to the faucets themselves. If you run it through your dishwasher, just make sure you don't have any expensive enamel casserole dishes in there; this stuff eats enamel! My kitchen countertops are quartz and it's no problem for quartz.
