IPA for cleaning records[edit]

I'm worried about the statements: "...used to give second-hand or worn non-vinyl phonograph records newer-looking sheen" and "Isopropyl alcohol should not be used to clean vinyl records as it may leach plasticizer from the vinyl making it more rigid[citation needed]." IPA can be found in lots of proprietary record cleaning solutions for vinyl records, sold worldwide. Homebrew vinyl cleaning solutions for vaccum and immersion-based record cleaners made using IPA, distilled water and an optional surfactant/wetting agent are used by many knowledgable collectors, libraries and archives (though many also advocate rinsing the record in distilled water alone afterwards, to remove all traces of the chemicals). I have never read or heard the claim anywhere else (besides this article) that IPA is significantly harmful to vinyl records. It is, however, widely acknowledged as being harmful to shellac records (because it causes binding chemicals to leach out of the shellac/filler mix and then the whole record just disintegrates) and one-time phonograph recordings, e.g. acetate or nitrocellulose lacquer on a glass or steel substrate (because it dissolves the lacquer). The only guaranteed to be totally safe way to wet clean these records (and even then, not all of them) is with distilled water only. I suspect that the author of these remraks in the main article is confusing vinyl with shellac. LDGE (talk) 21:13, 6 February 2014 (UTC)

I added a section about vinyl record cleaning, having done many months of research to prove that IPA / water mixes did not de-vinylise records, but this was removed. As someone who has been formulating record cleaning agents for many years, IPA should never bevput on shellac records, acetates or laquers as it will destroy them.

Uses: Solvent section[edit]

This section is riddled with 'citation needed' and several other pointers in certain sentences, but not in others. For example why does:

"It is used to clean LCD and glass computer monitor screens (at some risk to the anti-reflection coating on some screens..."

need a citation but:

"...and used to give second-hand or worn non-vinyl phonograph records newer-looking sheen"

does not? The next sentence is the same, and it makes for a messy read. I would suggest removing them altogether since everything mentioned is very common knowledge and widely accepted anyway due to it being one of the more common solvents that people use. — Preceding unsigned comment added by (talk) 22:32, 4 July 2014 (UTC)

IUPAC Name[edit]

In the infobox, the "IUPAC Name" is "isopropyl alcohol", but is "isopropyl" proper IUPAC naming? Busukxuan (talk) 15:43, 27 July 2014 (UTC)


I added [citation needed] to the sentence "Isopropyl alcohol is denatured for certain uses" because it doesn't make sense within my understanding. IPA is sometimes used as a denaturant for ethanol, so I can't understand what the point of adding some other denaturant to it would be. I looked for, but failed to find, a reference to denaturing of IPA. I left the sentence in, in the hope that the original writer knew something that I didn't and that someone would explain it to the reader who was as confused about it as I.--Wcoole (talk) 20:09, 8 January 2015 (UTC)

Orphaned references in Isopropyl alcohol[edit]

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Isopropyl alcohol's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "PGCH":

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT 19:31, 9 April 2015 (UTC)
