How to remove hardly embedded dirt from record groove?
Hello,
I am a record collector, and I have a few 45s (7" records) that have some embedded dirty spots in the groove that have survived all attempts I made for cleaning the vinyl. I tried Fantastic cleaner, then demineralized water/alcohol solution. I let the record dry. Then I tried scraping the dirt with my finger nail, then with a sewing needle under strong magnification. Nothing takes these dust bumps off the record, no matter how hard I try to scrape them off. I fear to scratch the record because it's in excellent condition otherwise, thus worth trying to clean better. These dirt bumps make "pops" when I play the record. Is there something else I could try to remove these dirt bumps from the grooves? It appears to be hardened glue or somthing like that. Thanks in advance for any advice. Louis-Luc |

Louis-Luc Are you sure the bumps aren't imperfections in the vinyl pressing? |

Louis-Luc Are you sure the bumps aren't imperfections in the vinyl pressing?- Hide = quoted text - - Show quoted text - No. These bumps really come from embedded dirt. I see it clearly, and even more when I magnify the groove. It's under the form of a line that goes throughout the whole song, but apparently someone tried to clean it earlier because it has gone partly, leaving a white line where there used to be more of this stuff. On another record, the dirt spot has the shape of a small circular stain, that pops for about 10 revolutions. I have not been able to clean this one as well. I don't dare poking more with the sewing needle, becaus I don't want to damage the groove walls further. Any way to dissolve these spots? |

I have found that the 'Old Colony Sound' "Reg Williamson" method of using a viscous goop spread on the record, allowed to dry, and then pulled off the record in one contiguous sheet with a piece of Scotch tape to leave all records essentially pristine. The goop flows around pieces of detritus such as the ones you describe above and when it dries, it traps them in the suspension. When the dried film is removed from the record surface, it pulls all the trapped foreign matter with it. This system was once sold by the makers of Empire turntables who sold it in a large squeeze bottle with a foam applicator on the top. It worked magnificently and perfectly. Records so treated actually LOOKED cleaner after the film was peeled off. The Old Colony kit requires that you mix the goop yourself and figure out your own method of applying it . I use a piece of soft foam plastic sourced from a local plastic supply house. http://www.audioxpress.com/bksprods/products/km-9.htm |

The main solvent for ordinary tape-glue is ethyl acetate. It works marvelously well. However, I suspect that it is not good for vinyl. In the usual suspect lists its compatibility is listed as "good" or "fair" which in this context might mean "bad". Caveat emptor, but it is worth a try on a worthless record. Doug McDonald |
