A record that has been stored flat under weight in an Indian summer is not a record any more.
What actually destroys them
Heat, which warps vinyl. The warp is permanent and it is the most common irreversible damage in the category.
Weight. Records stacked flat press on each other and dish.
Humidity, which does not hurt the vinyl much but grows mould on sleeves and glues inner sleeves to jackets.
Dust, which is what you actually hear as surface noise.
What to do instead
- Upright, vertical, snug but not tight. Leaning records warp along the lean.
- Away from any outside wall and any window, and nowhere near the top of the house.
- Disc in an anti-static inner sleeve, jacket in an outer sleeve.
- Do not store the record inside the jacket under weight — the same seam that splits in transit stretches in storage.
- Silica in the crate during the monsoon.
Cleaning
A proper clean before storage prevents dust being ground into the groove on the next play. Dry the record fully before it goes back in the sleeve; a damp record in a paper inner is a mould problem waiting.
What it costs
Sleeves and a crate that holds records upright. The expensive mistake — a warped box of records on a hot afternoon — costs far more.
Questions people ask
Can a warp be fixed?
Treat it as permanent. Flattening methods exist and are not reliable.
Should I play records I am storing?
Occasionally is fine. Dust and static are the enemies, not use.
Is a cupboard better than a shelf?
Only if it is dry and not against a hot wall.
