Pesach Questions

I assume my plastic Soda Stream dispenser can be surface cleaned and used on Pesach. Is this correct? I am planning to get new bottles. I usually remove the water deposits on the Soda Stream with a vinegar wash. Is this a problem? Come to think of it, I also clean my urn with a vinegar wash (cold). Problem? 

A cleaned Soda Stream dispenser is a Kosher l'Pesach Soda Stream dispenser, as the dispenser typically does not come into contact with hot chametz food. Even the vinegar was, I assume, not heated when you used it as a cleaning agent. An urn would in principle follow the same rule regarding the use of vinegar-as-cleanser, but it is our practice in any case to kasher urns, with "hag'alah". This is because the urn itself becomes quite hot, and typically sits in our kitchens in close proximity to - and sometimes even in direct contact with - chametz food. The specific instructions as to how to do "hag'alah" on an urn, are found in the Halacha How-To about kashering applicances, which you can access at www.bnaidavid.com/pesach (scroll down) .
