Hey All- I don't have record cleaning machine but I do have my own method I've been using for years that works very well for me....Dawn dish detergent, isopropyl alcohol (91%), & distilled water....rub gently with an extra soft sponge, let sit for a minute, then I get into the grooves with a delicate nylon brush & rinse thoroughly....I buy a lot of used records so this process is only meant to be carried out once per record for initial deep-cleaning....My question is: Would tap water be problem instead of distilled water... my faucet has really good pressure & could really clean out those grooves but I've read that tap water contains minerals that could be bad for my records...any thoughts?

You could use tap water, if you rinse with distilled. Actually, boiled (and cooled) water would be better than straight from the tap.

Cheers,
Alec

What effect does boiling and then cooling the tap water have as far as purity is concerned?

Boiling will remove some of the hardness = calcium carbonate. Look in the bottom of your kettle.

I wouldn't use dish detergent on records, they contain alll sorts of chemical nasties.. Crying or Very sad

Tap water is too hard and contains impurities, better to use de-ionised water from any motor spares retailer, and it 's very cheap (1.49 GBP per Litre).

It's a little more complicated than that. I think you need to acquaint yourself with some of the chemical principles associated with water hardness. To start with, calcium carbonate does not cause hardness.

Limestone is calcium carbonate. Dissolved calcium carbonate is the major cause of hardness.
From Wikipedia:
Hard water is water that has high mineral content (mainly calcium and magnesium ions) (in contrast with soft water). Hard water minerals primarily consist of calcium (Ca2+), and magnesium (Mg2+) metal cations, and sometimes other dissolved compounds such as bicarbonates and sulfates. Calcium usually enters the water as either calcium carbonate (CaCO3), in the form of limestone and chalk, or calcium sulfate (CaSO4), in the form of other mineral deposits. The predominant source of magnesium is dolomite (CaMg(CO3)2). Hard water is generally not harmful to one's health.

Alec

Do not use tap water. And if using distilled water, it is more available now, and you use dish soap to wet it, you should only need a couple drops to a litre. Try small drops untill it wets the vinyl. If you weren't eating off the record I don't see a reason for heavy cleaning. Not being sarcastic, and I have had many records that were very dirty. For those I use Simple Green, and about 15 ml /L. I mean they are so dirty they should be tossed, but they come out neary prestine. I haven't tried Electrosol or dishwasher rinse agent, but I think it would be safer than heavy duty dish soap, but dish soap does have lubricating properties. I use a vacuum cleaner which is an upholstery brush with a 1/16 inch slot in it and velvet edges. A couple drops of water couldn't kill it?

....rub gently with an extra soft sponge, let sit for a minute, then I get into the grooves with a delicate nylon brush & rinse thoroughly ~Quote

Sounds good..But make sure you rinse with distilled H2o.

Calcium carbonate is insoluble in water, as anyone with a high school acquaintance with chemistry would know. So "dissolved" calcium carbonate is an oxymoron if ever I saw one. Aqueous calcium ions in solution on the other hand are one of the components causing hardness in water. This is stated quite clearly in the Wikipedia article which you have misinterpreted. Learn some chemistry before copying out things you don't understand.

Yes, avoid tap water. Distilled water is very cheap and easy to get (sold in auto stores.)

Then lets get specific: Rainwater dissolves a bit of carbon dioxide from the air, and becomes a weak carbonic acid, then, seeping through limestone or chalk, ends up with calcium ions and carbonate ions in it. This in turn is capable of precipitating out as calcium carbonate.
Please identify that deposit in the bottom of your kettle.
Go back to your books and learn some real chemistry.

Yes. You live in the United States so you should be able to get a water quality report for your area and determine the hardness of your water. I found my online(!) by Google-ing "water quality your city". If your tap water is hard, then do not let it dry on your records. Rinse with distilled water.

My water is considered moderately hard. The hardness (as CaCO3) averages around 91 ppm or 5.3 grains per gallon. I still use tap water for cleaning my records. I dry records quickly or use distilled water.
I also use Dawn dish washing liquid. It has all the chemical nasties required to break down dirt and remove greasy smudges. Smile

In the UK, water hardness varies greatly. In many places you need to clean kettles and the like quite frequently with limescale remove, whereas where I am, in Plymouth, we have very soft water and in 3 years I haven't seen any limescale buildup at all.

However, water in the UK is often treated medicinally, principly with flouride to reduce cavities in teeth. I would not think this would be particularly good for vinyl though. I have no idea what the chemical reaction would be.

why don't you put some tap water on an LP and let it evaporate, then you can see the deposits, if any. Also note, tap water contains suspended solids, something you don't want left behind. As someone has suggested upthread, tap water would be OK, if you used pure water for rinsing.

I would also suggest you use a washing up liquid, and let the suds do their stuff for some while, remember Andy Warhol, and his 15 minutes of foam?
