Storage of vintage televisions and damp environment

[Retro-valve-guy]

So I have a question about storing televisions. I plan on storing them in a wooden shed (for a long time) which has no water leakage, now what I am concerned about is moisture and damp environment which can destroy vintage sets and the shifting between cold and warm weather, how or what would be the best way of protecting them in a shed from the elements of weather ??

Someone said to me cover them up with garbage bags.

Hi. I have a few sets I keep in a lock up they are long term projects or scrappers kept for spares
I managed to get some large polythene bags from a mattress shop. They are big enough to make a bag that most sets will fit inside. I used strong tape to seal the seams. I packed the sets on a hot dry day. One I unwrapped recently was preserved with no signs of corrosion at all.
I also keep spare autochangers in a shed sealed in bags They seem to survive ok.
You can also buy packs of damp absorbing granules, maybe one of those in the bag would help? A bit like a Getter for damp!

Rich.

You can buy specialist bags that have an airtight zip-closure, and a nozzle so you can connect a vacuum-cleaner to it and suck the air out! They're intended for storing clothes, blankets etc- the sucking-the-air-out squeezes the contents down to a smaller space.

I'd suggest using these, and also buying some silica-gel schets to seal inside the bags before evacuation, so there's no residual humidity to condense and cause mold.

When I stored away a load of my sets for a house move, I got a load of second hand bubble wrap from work, and a couple of rolls of pallet wrapping. I wrapped the item in bubble wrap, and in some cases I used bits of cardboard around vulnerable edges and corners, then wrapped the whole thing in the pallet wrap, which sealed it. Only downside to this is that it's not really re-useable, well, the bubble wrap is, but the pallet wrap is a single use thing.

Regards,
Lloyd

This made me think of this: https://www.youtube.com/watch?v=9YEXQwnyMms I think some caution is a good idea.

Hello,
I agree with Hans. I would not advise the vacuum bag idea.
If the TV had a back 20in by 20in that is an area of 400 sq in. Apparently small car vacuum cleaners can pull about -0.5 psi which is 200 pounds on the back so if a powerful vacuum could pull -1 psi that would be 400 lbs which could damage the tube etc. (A vacuum of -1 psi wouldn't reduce the the quantity of air or water vapour by much.)
Hot air can contain more water vapour than cold air so in theory it would be better to bag them in dry cold weather than hot.
Yours, Richard

Instead of using tape (which can lift or the adhesive degrades over time) what about one of the heat sealers seen on the shopping tv channels? Eg

There are also active enclosure systems designed for very expensive cars etc eg

A small positive pressure within container would be more effective in inhibiting ingress of moisture
