Ultrasonic Record Cleaner- any feedback
 
I have read the excellent thread on Ultrasonic cleaning by Scalars circa 03/2008.

There is mention of possible damage to records using this method. A year has now passed- can I ask if any problems have been experienced?

Hi,

I have quite good results in the US vinyl cleaning.

Samples of two records before and after cleaning:
Record I in the Initial state
Record I after US cleaning


Record II in the Initial state before cleaning
Record II after US cleaning

Files are placed on Russian site. For download you need to put 4 digits in window and push button "Далее".

Both of records have clicks.
Record I is very noisy in the initial state and hard to hear music itself. After cleaning the record I is more appropriate for music listening not crackles.

On the record II not too much crackles but cleaning reduce it numbers too.

Scratch crackles and wear noise remain on the record but sound after cleaning is considerable better (on my opinion of course :) ).

The files were deleted from server some time ago.

I have a new sample of record before cleaning and after cleaning.
Now I use improved cleaning procedure which give more effect than before.

First side of LP before cleaning.

The same side after cleaning in ultrasonic bath.

Both files had compressed as flac.

There is a lot of talk about this method in a Norwegian forum, and amongst those who use this method, nobody have so far registered any damage to the records. I have made such a machine myself, and is very satisfied with it. In this thread (norwegian) you can see a lot of different machines made of this ultrasonic cleaner.

This are 300 Mbit Free Lossless Audio Codec (FLAC) files - download time aproxx 1 hour at my presently download speed. What is the reason for this kind of file with such large store reservoir?

There is late answer but I hope not a useless.

My cleaning procedure looks as the following:

1) Pre-washing
I clean LP by hand-washing using a isopropanol based cleaning liquid. (~25% Isopropanol alcohol, several drops of surfactant and distilled water till 100%)

Washing is not long - less than 1 min but it removes main fatty tracks (fingers etc.).

2) US bath-washing.
duration 10-30 min at 2 rpm. Celsius. Add few drops of surfactant in the bath.
Water in bath is heated till 40 degree It is an optimum for vinyl. At higher temperature it may wrapping LP. Be careful at heating because US bath heat itself also and is optimal to heat water up to 35 degree the rest will be done by the US power ;).

3) Drying.
I use a quick and may be not gentle procedure using vacuum cleaner.
I use a plastic nozzle with wide and narrow gap. The nozzle covered by a thin tissue without nap.
I remove a water droplets from LP surface using the prepared VC.
Plastic nozzle covered by tissue enough soft and safe for vinyl surface.
