You can also use straight ammonia, put your chrome parts in a plastic container, pour in the ammonia till it covers the parts, cover and wait.
Only thing is, you have to becarful not to inhale the fumes, as they can be hard on your lungs....I am assuming the oven cleaner is the same thing, most likely the ammonia in the oven cleaner.
The only real difference is that you can reuse your ammonia. I have a bottle that I just use for stripping chrome, and I just pour the used ammonia back in the bottle.
