Any experience of one of these of very similar?

It looks good for the money.

Well I hope that I have made the right choice, but as far as I could determine they are all very much the same, and event the very costly made for purpose are likely to have these type of U/S baths inside. The proof of the pudding will be the end cleaning result I suppose. Fingers crossed

Well if it's no good you can just send it back, nothing to lose really except a small amount of hassle.

I suspect it will be quite effective though.

It's a very effective way of cleaning and I,m sure you'll be pleased with it. I have 10mm spacers between my lp's and it's fine. I think the spacing is more important in keeping the lp's apart while you are loading. The important thing on the spindle is to make sure the lp's are firmly clamped otherwise they won't spin and I guess that's what the knurled knobs are for. I also think some kind of filter is important otherwise you are reusing cleaning solution that is gradually getting dirtier. Do you know how fast the spindle revolves? I chose very slow 0.6rpm so that the liquid would,t be carried to the top of the lp and drip down towards the label.

Large tank capacity (7.5L)
●Low speed rotation (5 rpm) but it looks very slow in the video
●Fixture can be tilted up 90 degrees away from water
●Label protect to avoid wet during cleaning
●Clean 10 vinyl records in one time
●Uniform distribution of ultrasonic waves,
safety cleaning and good performance

an update on cleaning records with my Ultrasonic Cleaner
https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1

Monday last week the U/S cleaner arrived from Amazon, it is supplied by LBSEU in Shenzhen, China (although manufactured by Codyson, a specialist in ultrasonic equipment https://codyson.net/Product/370474.html), Amazon fulfilled the supply. It is advertised as being able to clean 10 records and pictures clearly show this, this is facilitated by a specific 10 records extension kit that extends the 5 record shaft and come with 10 additional record label protectors and and a support bracket for the shaft to rest on. Unfortunately on unpacking I found the extension kit was missing, rather disappointing. So I contacted Amazon and I had to return it and wait for a replacement, Amazon saying it was likely there had been a mistake with the order.

Yesterday the replacement arrived and yes you have guessed it no extension kit to enable cleaning of 10 records. So back onto Amazon and they have checked on the supplier and as they have near 100% feedback and have previously correct issues with orders are in the process of contacting them to resolve, so fingers crossed.


Anyway I decided that I would try out the unit as it is here, and below are my findings.

Firstly the unit seems to be very well made, and is a bit less utilitarian than a lot of ultrasonic cleaners on the market. The record holder is quite well made, and the record label protectors work very well. The motor seems to be very powerful and spins at a sensible speed. Loading records is relatively simple, by having the motor assembly on the supplied bracket in the upright position record protection discs and records can easily be loaded and finally the knurled nut tightened to clamp the 5 records. You then simply lower the records into the cleaning bath by rotating it through 90 degrees. The unit also comes with plastic spacers so any number of records from 1-5 can be cleaned as required.

This unit has a preset maximum temperature of 40 degrees and will cut out if that is reached. It defaults to 5 minutes cleaning cycle, but can be raised or lowered.

The cleaning fluid I have decided to use is from a recipe that I found was being used by several record enthusiasts and the mixture was advised by a chemist. It is 5.7L of Distilled Water, 300ml of 99% Isopropyl Alcohol, 9ml of a premixed Triton X100 solution(surfactant). This gives about 0.15% concentration of Trition X100, which is more than enough, it is highly concentrated and powerful in its pure form! If you are not keen on IPA then replace it with distilled H2O, although it does aid in grease deposit breakdown, fingerprints etc.

Note - Triton X100 is a very powerful surfactant used in Labs to scrupulously clean and destroy bacteria, viruses and manila matter, so DO NOT get it on your hands, wear gloves, read the safety instructions.

Triton Solution mix 5 ml (1 teaspoon) of Triton X-100 with 45 ml (9 teaspoons) of Distilled Water.

I selected a batch of 10 records that I knew I was not happy with from my previous cleaning attempts, 3 in particular had that annoying background crackle/pop that was possibly due to groove dirt, and possibly nicotine from smokey environments. The other 7 were not perfect just had the odd crackle pop with no sign of surface marks.

On went the first batch of 5 records into the above solution for 5 minutes, once done I popped them out onto a Knosti record rack and put the next 5 records, whilst they were spinning I rinsed off the first batch with Distilled H2O/ILFORD ILFOTOL WETTING AGENT, (500ml distilled H2O with 2ml ILFORD ILFOTOL) and then hoovered off.


The result.

All the records looked spotlessly clean with not one fingerprint left in sight, in fact they all looked virtually new.

Led Zeppelin III, this has been an annoying record for me which was given to me, it looks in VG+ condition but had relatively high level of background crackle pop even after previously having been cleaned 3 times. After the Ultrasound clean there was a huge improvement, the sound floor, and dynamics being greatly improved, but there was still some crackle pop in place although much reduced.

Sinead O'Connor a similar issue to the above and once again a big improvement.

Alice Cooper - Love it To Death, a favourite of mine but with background noise previously, after U/S cleaning like a new record, quite amazing.

Miles Davis - Kind Of Blue, a VG+ record but with background noise here and there, now now groove noises, near silence between tracks and great dynamics.

I cleaned some more records and re-cleaned Led Zep III, Sinead O'Connor and now very acceptable, the are a few pops on both probably due to surface scratches, but much more listenable now.

So to sum up, this is the most successful record cleaning I have ever done and some records are now playing like new, so I would recommend anyone who wants to get the most form their vinyl to get an Ultrasound cleaner. At present I can clean and rinse dry around 20 records in an hour, which is reasonably acceptable if you have lot to do.

By the way the ILFORD ILFOTOL also acts as a anti-static treatment so is worth using and it can be added to the Ultrasound solution as well, you would need 25-30ml to 6L. The solution should be good for 50 to 100 records depending on how dirty they are to start with, I will stick to 50 records per batch.

A quick follow up on how I am generally finding Ultrasonic record cleaning.

So far I have cleaned 372 records, batches of 35-50 each morning, which takes about 1.5-2 hours, I am doing 10 records at a time in the U/S unit with them in it for 15 minutes, whilst each batch is in the U/S I rinse off the previous batch with distilled H2O with release agent, and vacuum dry. Taking off and re-loading 10 records takes about 10 minutes being careful. So I reckon on average its about 2.5-3 minutes a record, which is pretty good through put. I have been filtering the cleaning fluid after each batch of 35-50 records and as is replaced every 2-3 batches.

After each batch I usually play two or three from each batch, selecting ones that needed reclining or I hope will have improved. So far I can say all had improved, nearly all to a very high standard, with near silent background noise and seemingly improved dynamics/resolution. The odd record has had persistent crackle/pops and as a result have been through several cleans, I would say that 50% of these clean up, so are fundamentally just very dirty, 3 records whilst they have improved still have crackle and pop so they have had a hard life IMO and need replacing. I have also cleaned new records that have only been played once or twice and have to say that in a lot of cases resulted in a quieter background and seemingly improved headspace.

So overall a very successful exercise, and well worth it, just few more to clean though.
