I have stored 78s in a none-climate controlled area for many years, (around 15 years), where they're exposed to temps ranging from sub-zero to summer heat.  So far, I haven't noticed any ill effects from these conditions.  But I do make it a point not to bring a record from winter cold to indoor heat, which is a little frustrating because it means I don't have access to the records for 7 months of the year, (October to May).

 After a fire at my shop some years ago, I'm still trying to salvage many 
records that deteriorated from moisture - and I find a very old school 
technique that has amazing results. Organic compounds in the shellac are 
affected by moisture and freezing - it's not a good idea to store shellac 
78s in improper conditions. In reviewing some of my original dubs from 30 or 
so years ago, i'm aware that the records weren't perfect even before the 
fire, but I have found a way to clean and improve the surfaces by using - of 
all things- my Victrola Credenza.

I completely coat the playing surface of the record with my cleaning 
solution (1 drop of Sunlight in about a cup of water). I place a new steel 
needle in the gramophone at the start of the record, then play about 15 - 20 
seconds of the record to grind the needle to the shape of the groove .

 You can hear the hiss gradually increasing as the needle conforms to the 
shape of the groove. this is usally about 1/2 inch into the playing surface. 
I then return the reproducer to the beginning of the record and play a 
second time, this time playing the complete record. I notice very little 
hiss at this point, but when the needle reaches the unplayed portion of the 
record, the hiss turns on like a switch.

By using the gramophone like a lathe, it makes even a very grey record shiny 
again.

I then place a bamboo needle in the gramophone, and again play wet. this 
will polish the groove even more. Next, I dry the record and play again with 
the bamboo needle, which further polishes the groove. I then use a dry nail 
brush, spinning the disc on a very powerful 'Micro' transcription turntable 
to activate the natural lubricants in the record.

Now, it's ready to record , and the results are spectacular. Most of the 
hiss is gone, and the record sounds far better.

A note - I use the term 'hiss' advisedly - with 78s, what we call hiss is 
more of a cumulative effect of a great number of clicks.

As such, I find that de-click application with minimum settings will remove 
much of the remaining hiss, without any obvious intervention.

The worst thing is that gating effect, with sibilants popping out at you - .

Hope this technique will help with those rare, beaten up records - it wirks 
for me-mickey
