Precision Aqueous Cleaning of Vinyl Records

Thanks, I read your suggestion of laundry detergent, but my difficulty is that it leaves a lot to interpretation, especially as someone who is not au fait with the ingredients. Ecover Zero appears to meet your description, and it does state a list of ingredients. I wonder if you could have a look and see if you think it would be suitable?

Neil,

This is an amazing piece of work. I've just read the 3rd Edition and it was so enlightening! I would like to plan a procedure to clean my vinyl collection, which has mostly been unplayed for 30 years since I adopted CDs. I think a certain amount of mould has developed; I've test played a few titles and, besides the surface noise, I found the stylus picks up a lot of debris, and soon it's not riding in the groove and the record sounds very distorted.

Anyhow, since I'm based in the UK, the info you have added on alternatives to your preferred cleaning products is very useful indeed. The Alconox products are difficult to obtain here but it looks like I could get BASF Dehypon LS54 easily and inexpensively. My question: Is there any reason Dehypon could not be used both for the pre-clean, and the final wash stages (at different dilutions)? I note in chapter XIV on UCM you allude to using Dehypon for pre-clean at 0.025 - 0.05%, but I don't recall seeing that option mentioned for your manual procedure.

Thanks for your help
Rob

Thanks for looking at the Ecover Zero Non bio. It's very reassuring to have your thumbs up.

Now for the acid stage, I see that  - in the absence of Citranox - you suggest supermarket distilled vinegar diluted 50/50 or 75/25 with distilled water, with an additional few drops of wetting agent. Is the Dehypon ok to use as wetting agent in this mix?

As an alternative to vinegar, is worth considering a solution made up from pure citric acid crystals which are easily obtained here?

Thank you,

Rob

@pindac That's a great suggestion about the pressurised bottle for the final DW rinse. I will get one.

Just as a PS to this thread... I've now purchased a 1 litre bottle of BASF Dehypon LS54. I don't expect to ever consume this bottle in my lifetime, since it will produce 2,500 litres at the recommended dilution. Given it's quite expensive, if anyone in the UK would like to send me an empty bottle of 50 or 100ml, I am happy to return it to you filled for the cost of postage.

Cheers
Rob
