I see where some folks say to store the cloth filters submerged in water, while others say to store it dry. What say you about pros and cons for either method.

Best to keep that filter either stored damp in a plastic bag or in a cup of water. Allowing it dry has been reported to allow the coffee oils/retained fines to cause off flavors. So far, by keeping my filter submerged in a small pyrex dish between uses, it has been perfect. So, while I can't offer anything in the way of negative comments towards drying, enough people have spoken out against it.
It really depends. I use JoeGlo to clean it every time that hot water washing seems to fail. So, it depends, but I've had the same filter for well over a month by now.

That's because you/they are reusing a dirty filter. I've stored mine dry for 3 years now with no issues but they only see one use before they get cleaned again in a boiling hot Oxyclean Free solution. Personally the idea of making our daily vac pot brew with a dirty wet filter isn't very appealing so I keep 4 filter assys. in play so I only have to clean them every 4 days.

Cleaning mine with boiling water leftover from brewing following each brew with a more extensive cleaning every 4-5 uses works perfectly for me. I have never experienced off flavors, extended draw down times, or buildup. A good rinse in very hot water following each use is plenty IMO. To the OP, do what works for you!

I give it a boiling water bath, and store it in the freezer. Every week or so I use an oxy clean or just swap it out for a clean patch of poly (I use the filter holder that takes any medium). I haven't found a method that reliably prevents rancidity other than oxy and/or freezing.
The hot water soak following each use gets all the moveable fines out of the filter. Regardless of how well I clean the filter with hot water, it still retains oils and some fines, which is why I store it in a cup of water. If it is allowed to dry, those oils and fines can become rancid and the cloth will begin to impart off flavors. I also choose not to JoeGlo my filter after every use, because cloth filtration requires seasoning of the filter - IMO, full cleaning of the filter following a use would defeat that purpose.
My opinion is based on the fact that I have never had off flavors appear in my siphons and this method of filter maintenance is based on Barismo's blog posts about filters/siphons.

I don't have a vacuum pot, but with all this work cleaning, is it really worth it? They look like fun in a chemistry lab way, but is the coffee so good to be worth the fuss?
