dr_weazel Posted December 18, 2007 Share Posted December 18, 2007 CDs are also much easier to scratch You'd think ALL the DJ's would want to use them then! ooooohhhhh, not THAT kind of scratching... Link to comment Share on other sites More sharing options...
Known One Posted December 18, 2007 Share Posted December 18, 2007 Even though the tracking force of most stylus are usually quite small (~1.5 grams), this force is applied to such a small area that the pressure on the walls of the groove can be surprisingly high... Simple calculation based on these figures gives a stylus pressure of 240 grams per square mm, or 340 pounds per square inch (Source) If you include the fact that the walls aren't flat, those figures are higher If you think about that, then adding an abrasive to the story will wear the groove faster over time... Distilled water is used for cleaning records and CDs for many reasons. Its precise chemical makeup is known, it will not leave any residue behind, is safe to use, and is inexpensive. Water disperses static charges and counteracts the increase in conductivity from the pick-up of salt deposits from finger prints. However, water alone cannot dissolve grease, thus surfactants are used as additives to enable water to be a grease solvent. Surfactants break grease surface bonds and allow water to penetrate grease solids, causing swelling and then random dispersion. Here's more info... here I say soapy water and then distilled water to rinse it... then rinse it again... proppa Link to comment Share on other sites More sharing options...

Hakomi Posted December 18, 2007 Share Posted December 18, 2007 Gullability is probably the main ingredient The same type of people who think they aren't getting enough Vitamin K - its POTASSIUM people! Yeah this coming from a guy that spends 25 dollars on a twelve inch instead of 15 Ill just use the cash that i save on my records to buy a decent cleaning cloth or brush. That wont scratch my records to shit and cover it in more dust like a normal cloth will. This is quoted from the same source catalyst posted. Care of LP's, 45's and other Vinyl Records Most LPs and singles released after the early fifties are composed of polyvinyl materials and are more durable than it's predecessors. When cleaning vinyl records, I recommend a 50/50 solution of isopropyl alcohol or denatured alcohol (fewer impurities) and filtered or distilled water (again, fewer impurities) And the cleaning fluids i have read contain a mix of isopropyl and distilled water i think thats pretty much the deal This is also on there so both ways are presumably possible i would say one would just be easier A mild detergent, such as Johnson and Johnson Baby Bath, can be used in small amounts with water with no rinsing necessary.

zeb Posted December 18, 2007 Share Posted December 18, 2007 sounds like a mild soapy water mix is the best and cheapest way to go then..... Link to comment Share on other sites More sharing options...
Specs Posted December 19, 2007 Share Posted December 19, 2007 I use isopropol alcahol with a anti-lint cloth like used for glass cleaning, seems to work pretty well, just dilute it with some warm water and put it in a spray bottle. works mint.

thereseq Posted December 21, 2007 Share Posted December 21, 2007 Hammer Hardware (at least the valley rd one) has 1 litre bottles of Isoprobyl alcohol for 15 bucks. A 50/50 mix with water is good as gold Link to comment Share on other sites More sharing options...
