 | vinylpassion Member since Jun 2011 618 Points | This is a problem that has bothered me for years, I have several albums that have been stored flat for 20-30 years, the polythene inners have stuck to the discs and have left what i can only describe as sweat marks on the vinyl, the records are otherwise clean, but i have tried many methods to remove these over the years and nothing works....any ideas? |

 | Dr Doom SUBS I wanna eat an artichoke once in a while Member since Feb 2008 25248 Points Administrator | A.K.A. 'Bag Rot' - a charming name I'm sure you'll agree. In my experience sometimes it comes off very easily (lighter fluid and a cloth works well) but in some cases it's permanent and nothing will remove the marks. It also seems random as to whether it affects play or not. Sometimes they look awful but play fine and sometimes they go all hissy.  |

 | Trainman Trainman Member since Jun 2014 2559 Points Moderator | Have you tried isopropyl alcohol. That's what I clean my records with (but DON'T use it old shellac). The local classical station here in beertown used to actually wash their records in warm water and dish soap (didn't do the labels any good though). |

| Neil Forbes Rock, Country or R. & B. - Classic Hits for me! Member since Dec 2014 252 Points | I generally apply a mix of water, methylated spirit and dishwashing detergent to the record with a paintbrush just before playing(either the wanted track or whole side) when recording the track into my computer to convert to MP3. This has the effect of lubricating the surface and negating the static electricity that might be present on the surface. |

| Readers Member since Jan 2015 2 Points | This needs some examination. I think that the polythene may have leached some corrosive ingredient and etched the marks which mke it look like ripples, fogg. The diseased surface needs close examination under a Leica microscope to detect what really might have happened, then a remedy might be suggested |

| Trainman Trainman Member since Jun 2014 2559 Points Moderator | Find a friend who does a lot of painting on model railroad equipment and see if he's got a mini sandblasting booth  Actually, we have much the same problem with a brass model that's been wrapped in foam the last 30 years. The foam does NOT want to come away from the brass! To bad record sleeves were not made with acid-free archival materials. |

 | Fokeman I used to have a good memory but now I can't re Member since May 2011 5096 Points Moderator | Island had the BRILLIANT idea of using plastic instead of an inner sleeve and then foam rubber at the entrance. Of course there isn't one single LP from the handful they made which has survived with the foam intact. Without exception "EL PEA" has molten foam rubber on the inner sleeve and I think there was a Transatlantic LP which had the same disastrous fate. |

 | carryonsidney a happy disposition is an omnious sign.... Member since Feb 2010 1707 Points Moderator | trainman - if your brass model is solid brass, take it to an Electro plating workshop they should be able to dip in it Trich or similar to dissolve the foam off. |

 | The_Vinyl_Junkie SUBS My body is on the diminishing streak. Member since Dec 2011 8082 Points Moderator | Just thinking about Tricho, I would be tempted to get any old useless record from an op shop and give it a test run with the Tricho. It is an excellent grease remover as I used it for removing grease from clothing by hanging the clothes in a "Tricho Bath". Trouble these days you would need a licence to buy it. |

| Trainman Trainman Member since Jun 2014 2559 Points Moderator | For brass, any powerful solvent works, but then that also dissolves the protective clear lacquer finish many makers put on the model, which the "collector" would like to keep. If you're going to paint it, no problem Back on the topic of records, I'm not sure what they call "Tricho" in the US, but I would be wary of anything that would "dissolve or soften" the foam, because it would probably also dissolve or soften the record too |

For all the things I've cleaned there was nothing detrimental. In Oz Tricho is short for Trichloroethylene. http://en.wikipedia.org/wiki/Trichloroethylene |
