Using de-mineralised water for vinyl cleaning

[da2222]

Hi

It's virtually impossible to find a source of distilled water to use with the knosti cleaner here in Italy but de-mineralised water is readily available- would it be suitable to use or not? (Procedure: wash with de-mineralised water and 'Winyl Pro Clean 6' solution followed by rinse in separate knosti bath) Any opinions as to suitability or otherwise? Thanks!

Is the 'demineralised water' the same as 'de-ionised water'? If it is I wouldn't worry.

From the net:" Deionization and demineralization, while being similar, have key differences. Deionization removes ionized salt from the water. Demineralization removes minerals from the water such as calcium, magnesium and many others"

In praxis and for your application it makes little difference.

Thanks, clearer now. I think...

Thanks, clearer now. I think...Is it an option for you to get some from a pet shop? I get pure H2o from a shop near me that sells tropical fish etc.

Presumably there is a Halfords equivalent there?

Get battery top up water, that’s de-ionised.

DI and Demin are basically the same,just different terminology as they use the same process to remove the Ion's.

However there is no industry standard for either as their applications can vary depending on what it is used for.Purchasing either is a lottery as if the conductivity of the water is not stated on the product,you could be buying tap water or worse.

You should be able to source EU pharma grade water in Italy,might cost a bit more,but it will be manufactured by an accredited company.

Whilst I was working in analytical labs we used DM and HPDM water for allsorts of jobs. If we ever got them muddled with each other it never ever showed up in the analysis. Personally I'd get the cheapest.

I use 2 Knosti baths one filled wit the appropriate L'art du son mix and one with de-ionised water from my local chemist.
Seems to do a good job

This is what I use:

Works great...leaves no spots.

Lovely ! Who'd've believed it ?:lol: I recommend murky pond water.

I've bought expensive pharmaceutical grade water at £12 for 5 ltrs and i've bought cheap Car Plan de ionised water at £2.50 for 5 ltrs and i didn't see any difference in its performance when used for cleaning vinyl

What you really want is 'Pure water' i.e. 0PPM water that has been through a combined filter, resin and RO system which is as pure as you'll get. A lot of mobile window cleaners use pure water these days and have their own filter systems. I asked my window cleaner if he had any to spare and he was more than happy to fill a few 5L containers for me for no extra cost.

Also worth checking out Spotless Water: https://www.spotlesswater.co.uk/ Basically unattended filling stations for pure water, meant for window cleaners but I don't think there are any lower limits on what you can dispense. At the moment if you sign up you get a key fob which has 20 pounds worth of credit for free. I've not used mine yet but my nearest filling station is currently 30 miles away but if I'm passing I will do.

Lloyds pharmacies sell pure warer.
5 litres for £8 if i remember correctly.

The ice in your freezer is pure. (That is, the stuff that forms around the surfaces)

[Oddball]

I collect the water out of my dehumidifier :eek:

[struth]

think you can overthink this water bit. any of the tubbed up waters used by hospitals etc should be fine.Ive never had issues and been using medical grade water for years.

Correct, though it'll need filtering for detritus. I've used this for years (triple filtered) and it's effectively distilled water.

[struth]

Yeah you don't want bits of chicken breast on the records.

Back when I worked in a lab we would use HPDM water or high purity demin. This was demin water that had then been passed through an ion exchange unit once more. We never really questioned it because we had to use it due to being accredited and all of the faff that went with it so I can't really say if it is a waste of time and money or not but with regard to cleaning vinyl records, I would personally say that any demin water would be a bloody sight better than tap water just don't be tempted to drink that damn stuff.

Thanks for the heads up, there is a filling station just down the road from me:thumbsup:

Excellent article - thanks for posting Barry.

I'm all for practical no-nonsense advice that debunks so-called secret, proprietary and over-priced commercial concoctions!

[struth]

Very similar to mine. Never had issues so cant be doing any wrong

I notice he recommends BP/EP grade water which I have been advocating for some time now.
