[78-L] Cleaning Lacquers.

[Ron L'Herault]

Unfortunately, I am going to mention a US product.   Windex, a glass cleaner
is quite effective in removing the film.  It is a blue colored cleaner with
ammonia, and perhaps it or an equivalent is sold in the UK.    Paint
thinner, which I believe is called mineral spirits, is also effective but
you have to follow it up with a soap and water wash, I believe.  I always
test things in the run-out area, letting them sit for a few minutes and
looking for haze, discoloration, deterioration of the surface.

Hi!

I recently acquired some dubbings of Benny Goodman broadcasts in 1937.
HOWEVER, the dubbings are on lacquer discs and have now begun to 
suffer from that thing wherein the surface turns a very grey 
colour...probably some form of slow chemical decomposition or 
whatever.

I'm sure that there must be something which could clean these 
lacquers and get rid of the loud noise this stuff makes...other than 
cleaning up the sound digitally, of-course.

Can any of you experts suggest anything to clean them with?
There's still a lot of good quality sound underneath it all! ;-)

I live in London, so please don't suggest a 'brand' of substance sold 
in the USA for I won't know what it is! ;-)

Earl Okin.
