Records not stored vertically for decades

Returning to us a Vinyl Source with a selection of Vinyl LP's stored for 20 years +.

That seems like a experience that can generate excitement, especially when some of the Albums in storage, might be worth a much more than the price from when acquired.

There might be one gem in their that can cover the cost of a Vinyl Replay equipment ? 

@soix I can't say enough positive compliments to the PAVCR Manual Cleaning Method.

It has blown me away to the point the US Tank is unused.

I have purified Albums, I thought I was never to play again when in contact with a Stylus on a on a quality Cart'.

Those Albums I would now let meet any Cart's Stylus and have no fears for the owner of the Cart' showing a concern.

@soix As you were informed earlier in the thread that you are the sole investigator of your concerns about quality of the Albums condition.

Your follow up response:

" Ok. I was mainly concerned the pressure from the weight would affect the grooves and the sound but not sounding like that’s much of a problem." 

If the Stack was quite neat, without too much edge overhang of the Albums perimeter edges between tiers, the idea of the Groove receiving compression is one that is less of a concern, as the Outer Raised Dead Wax Rim and Inner Raised Label will have been the points of loading. Hence, references being made to Ring Damage demarcation visible on Album Covers. The Grooves will have been recessed in relation to these two positions and been free from excessive force being applied.

If there has been an increased overhang of the Albums Perimeter Edges between tiers, The Likelihood the Offset in alignment is more that 50 % of the surface area of the Label diameter seems excessive, but the off set being more than the 50 % of the width of the outer Dead Wax, does seem quite viable. If this off set is seen in the stack, there is the likelihood the Grove have been exposed to  point force, where the Dead Wax was able to be compressed and add force to the Groove.

Note: Force applied will be if typical as a Storage, passed through an Albums Outer Sleeve and then the Inner Sleeve, there might even be a Outer Sleeve Protector in use as well. These layers of protection being present, where the point of force is being applied, is certainly an area where an amount of cushioning is also working against the hard / full contact force being exerted to its worst effect.

If the Base the Albums are laying on is perfectly flat then the lower Album should not be exposed to being compressed onto the uneven surface in the area of the Grooves.

As an optimist, I sense the Paper Sleeves may have been exposed to a accelerated deterioration as a result of the environments impact at the storage location. Proper Cleaning Methods will firstly correct any earlier used cleaning methods failings, as well as deal with contaminants from inner Paper Sleeves deterioration being bedded into the groove as well. 

I keep the original Paper Sleeve stored in the Album Cover, but use Anti Static Sleeves to insert the Vinyl into  following the PAVCR Manual Cleaning Method.

Ring Damage to Album Covers is quite likely.

Warping is also a risk. 

The question is when you do get to have hands on the Vinyl LP's once more, are the Storage methods to change, is the new configuration to be that the Albums are to be flipped to the Vertical for the period of storage until you can get to using them regularly ?!!!

Do not overlook that this Album Collection is very likely to be worth a reasonable sum of monies, it can also contain an Album or Two that are much appreciated in value as well. 

@soix The Post from @recordguardian a very appropriate name, has made it clear what is a ambient environment condition that can cause a warp to occur.

When hands on with the LP’s, this is one more consideration to be checked for and avoided, for this condition to be created in close proximity to the LP’s.

I don’t think there is an LP owner from their heyday of usage that has not had a LP warp from leaving an Album local to an external window that receives Sunshine.

I may have even been expressive of a wicked nature, where at a certain time, exposed a Sibling Brothers Album or Two to such a condition 👹

To overcome any concerns about playing Vinyl Horizontally after storing it Vertically. The Link is to show a type of device to help address such a concern.

@soix If the PAVCR Manual Cleaning Method is utilised prior to any replays of this collection of Albums, there should be very very little, if any evidence of contamination in the Groove when the earliest of the replays are carried out.

Purified is the most accurate term I can select for describing the Cleaned LP played fresh of the Cleaning Process.
