[78-L] A moldy issue^

[H D Goldman]

A 20 yr.+ evaluation of a wide variety of shellac, vinyl, Edison &  
lacquer discs have demonstrated that thoroughly cleaned surfaces are  
highly resistant to re-infestation by mold & mildew under reasonable  
storage conditions.  The test was conducted in St. Louis, MO in a home  
built in the late 1880's in it's original environment; forced air  
furnace, no ac, original wall paper in poor condition, etc.  High mold  
& mildew levels throughout the building.  Cleaned items were stored in  
closed metal cabinets & on shelves throughout throughout the house.   
Contaminated sleeves were either replaced with fresh paper sleeves or  
blown out with filtered air & reused out {in no way an effective  
method of generating an uncontaminated sleeve}.  Visual light  
microscopy & playback were used to assess record surface quality.

That said, the most effective long term treatment for mold &/or mildew  
infected discs is to thoroughly clean them, removing the growth & the  
materials on the surface that serve as the primary feed stock for  
biological growth.

While thoroughly cleaned & properly cared for vinyl pressings &  
Diamond Discs are very resistant to biological re-growth, it must be  
remembered that shellac & lacquer discs are inherently food for the  
bugs of your choice.  Nonetheless, with thorough cleaning & proper  
care, shellac & lacquer have shown considerable resistance to re- 
infestation.

Appearances are deceiving.  Incomplete cleaning leaves residues which  
over time can lead to permanent damage.

Regards,

Duane Goldman
