No, the whole point is to AVOID evaporation. Just spend fifty bucks
and
buy a used Nitty Gritty machine.

It was just a thought about using compressed air to physically 'blast'
the
water out of the grooves rather than evaporating the water. Could have
used a heat gun for that
No Nitty Gritty's on Ebay at the moment.

I agree with vacuuming grooves, but until this technique is available to
me,
I thought I would experiment with compressed air.
I used a sacrificial '45 and a home/auto air compressor at 8bar/115psi
through a 2mm trigger nozzle. The record with water/surfactant as
expected
produced a thin film over the surface and grooves. Rinsing produced water
clinging to the grooves due to surface tension but was removed fairly
rapidly with the nozzle angled at 45degrees and swept over the
record,progressing from one side to the other. About 20 seconds to
complete
the task. I did the job outside as inside the air would no doubt stir up
dust.
It looked clean !,new sleeves would be needed as the old sleeves quickly
returned dust.

Interesting

How did it sound when played?

I really need to do a before(regular cleaning) and after(regular plus
water/air cleaning),with a decent recording to do a fair comparison. I will
try to estimate debris reduction and not have excess record wear interfere
with this.
