I'd be afraid of corrosion before ghosting with those chemicals!
Although I use dish soap sometimes, scrub it really good, lots of bubbles. Then rinse it, scrub, rinse, until soap doesn't come out. Use lava hot water. Rinse after scrub/rinse for a minute or so.
If that doesn't work, baking soda! Get the inside of the pipe wet then pour some baking soda down it and let it sit for a while (an hour maybe). Scrub then rinse.
