Oh my god! There's nothing wrong with the bidet is there?
“Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".
“You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”
"You don't have free will. You have the appearance of free will.”
“There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

Just a quick net nanny warning for anyone new to using isopropyl alcohol: It evaporates easily from solution and the vapour is highly flammable at low temperatures, so its use in an ultrasonic bath at much above room temperature carries a fire risk, especially if a standard brushed dc motor is going to be used to turn the record.

Thanks for posting this Bernard. I'm very tempted....
By degassing the fluid for 5 mins on first use - does this require leaving the fluid to sit for 5 mins at 40C, then use it?

Good comment. I would not worry about the DC motor. However, if used in a kitchen, one needs to be careful.... better to open the windows!
I am using the Ultrasonic tank lid after use to prevent having to top-up the solution. I also want to gradually experiment reducing the volume of IPA in the mix.

It requires switching the ultrasonic ON for 5 mins at 40C just before cleaning.
Some info on the benefits of degassing ...

Thanks, that's useful. One more question.....I can understand that filtering the solution, wiping the tank clean and refilling it with the filtered solution would be sensible after a few cleaning sessions. Is there any advice on how often it's advisable to use new fluid? Of course if its dirty then new solution is needed but does it degrade? If the solution was left sitting in the tank for a couple of weeks or longer, is this considered to matter?

I partly answered in post #9 but I will add that I have successfully cleaned around 70 records with no impact on the sound so far.
I am planning to clean up to 150-200 records before filtering the solution with a 1 micron filter.
Once filtered, the solution can be used many times over with some top-up.
The tank has a lid, which can be used if the solution is left in the tank for a period. You can also store in a 5L plastic bottle.
Hope this helps.

This method of vinyl cleaning looks very interesting and i'm very tempted to give it a go, the initial post was very informative however the use of IPA had me a little confused at 1st until i realised people were talking about isopropyl alcohol and not Indian Pale Ale , seriously though wouldn't this work with a pre mix vinyl cleaning fluid such as the Knosti stuff?

Bernard, may I offer you enormous thanks for posting this very detailed description and list of components. I’ve been meaning to build myself an ultrasonic cleaner for a couple of years now but have yet to get around to it. Thanks to you I have just had the tank delivered (rather a nicely made thing it is too). So, another project for me to add to the list .
