Re: Cleaning the hose.
I can see where tapping it on a table might dislodge stuff that might be clinging inside of the hose but I'd be afraid that "whipping it" against a table would damage the hose. If not the first time then over time it would eventually break down the hose itself. Baking soda makes sense, too. It is good for neutralizing any acids that might be present in the residue that is trapped within the hose interior. Good ol' acid/base thing. Ahhhhh college chemistry at work! LOL Smoke happy.
