[78-L] More on cleaning lacquers

[H D Goldman]

Hi Gary,

Had we found water/Triton X-100 mixtures alone & a paint brush to  
afford safe & thorough cleaning of lacquers &/or acetates or shellacs  
discs for that matter, we would not have made an effort to develop  
alternatives.

Be careful when using non-ionic surfactants as they are only effective  
when used at very high dilution.  More is not better.

Cheers,

Duane Goldman
