I just wanted to say, that since Drano is lye (sodium hydroxide) which is a strong base, baking soda (a weak base) will not neutralize it. Better is to use vinegar, which is a weak (5% acetic) acid. Be careful whenever working with somethng as strong as lye.
As an aside, I have read that just pure lye from the Ace Hardware store might be better, since it doesnt have all of the additives (scents, surfactants, etc.) that Drano or Easy Off has. Anecdotaly, I have heard this helps with the blotchy, post strip apearance. I have no actual experience, but I read the internet A LOT!
