Cleaning 78S??

[pivot]

The brush-on peel-off substance is probably a PVAc emulsion, and I would be reluctant to use it on a 78.

Qoute fro the Old Colony site:

"The user needs isopropyl alcohol, distilled water and glycerin to make up the needed treatments."

I recall using a product sold by Pickering that was a peel off mask for LPs.

It sure smelled like it contained alcohol - I would not use any alcohol based product on a shellac 78, pretty much guaranteed to destroy it.

I also found a recipe here; it includes both Everclear (190 proof grain alcohol) and Elvanol. Despite its Tolkeinish name, the latter is a polyvinyl alcohol (PVA) product. Sounds very unsafe for 78s.

No alcohol on 78's of ANY type. Shellac a board, pour any kind of alcohol on it and see what happens; wrinkles at best, removal with methyl alcohol(methanol). I scrub my 78's with Photo-Flo 200 mixed as reccomended by Kodak on film, one capful to a liter of distilled water, put some on the record, put it on the turntable , and use a very soft (infant) toothbrush, rinse in tap-water, then rinse again with distilled and dry them with photo blotter paper, then let them dry on edge for a day or so. Finding very large diameter sylii for most phono cartidges is very difficult or imposible today. I've put most of my '78's onto Hi-Fi VHS format (with stills of the labels) which gives me 6 hours of Eddie Cantor, Al Jolson, Louis Armstrong, and Bob Wills and hopefully, it will be many,many years before I need to play the originals again. It actually works quite well, as awful as the concept is. Some "garage/attic sale" 78's I have to clean several times. More than once, first pass, all I did was make mud.

78's snap like crackers if handled improperly.

I found that out on the first one I cleaned and quickly adjusted my handling methods to suit them better
Luckily I practiced on one I didn't care about very much.

I was given a stack of 50s rock 78s that were extremely filthy from sitting in a basement for 40-50 years. It felt great to get them all cleaned up and put into new sleeves. I used a bit of very simple/pure (laundry) detergent and some vinegar in distilled water, then rinsed under the tap, with a final rinse of distilled water from a spray bottle. I made a DIY label protection system from peanut butter jar lids and a sheet of rubber, cut to size.

It all seemed to work really well, but I've still not played them to hear the results. Finally got around to getting a 78 stylus recently, so will be hearing them soon.

[Whitneyville]

I'm now using my Pickering XV-15 stereo cartridge with a 3 mil stylus and I built a "phase switch box" for horizontal cut and vertical cut (Victrola, Edison, Pathe) discs, that becomes dual mono out. My monster ex-radio station transcription TT in the garage with the Astatic cutterhead/playback cartridge does a better job on pure horizontal cuts, but it's 44*C in there at 11:36 PM local time.

Having had a 78 RPM record show on the state radio in Paris France for 8 years, 1000x55-minute formats (!), 14 to 15 sides per broadcast, I can assure you of the following:
-cleaning with a mild dish-washing liquid (Dove) and rinsing with distilled water is OK. Absolutely NO alcohol-based fluids.
-for airplay I used at least 5 stylus sizes: (in µm.) 50, 65 (std) and 65 conical truncated , 80 and 100 for acoustic, on a variety of carts (Stanton 680, 500, GE VRII, Shure SC35 & Pierre Clement Radio France models L7B).
- to get most of the surface noise out, I would spray on Johnson's regular PLEDGE onto the entire side and apply it evenly with a plastic baby hairbrush. Then I would wipe the excess with a soft cloth and play the record. "Pledge" evaporates with time (10 to 15 years) and is harmless to shellac. It also improves the stylus/groove contact because it is slightly "Sticky" (pun intended). The French equivalent of your L.O.C., "La Bibliothèque Nationale" uses PLEDGE on a day-to-day basis. After about 20 years this stuff turns powdery and a hard round painter's brush removes it easily and thoroughly.
Hoping this post will shed some light on those funny looking discs!!

Thanks for the PLEDGE tip! I knew about using glycerin, but it's so hard to clean-up after. My 100 year-old+ shellacs I worry about. Shellac isn't the most stable substance known to man, and newer records of mine have had "problems".

If you have ever set a wet glass on a shellacked piece of furniture, then you know why coasters were invented.
Do not ever play shellac records wet.

Cheers,
Alec

This "tip" really works. Do NOT use "Lemon PLEDGE", use the regular stuff. The smarts guys at Radio France Accounting always wondered what this show was doing with furniture spray cans!!!!

My "bottom line" is don't soak them or leave them wet any longer than absolutely necessary. Dawn or Dove or better (IMHO) P&G glycerin bar soap (castile) (I use a China boar bristle cheap shaving brush and an infant toothbrush) work well unless the grime is oily/greasy, then it's Ultra Dawn or sometimes 1:64/1:50 Simple Green in lukewarm distilled water, and work FAST. I think it's safer to clean a really grimey 78 several times fast, than to leave it wet long enough to get it clean in one pass. I dry them with my wet vac, then a well-washed "beefy-Tee", then let them air-dry for 2-3 days in the dish rack before cleaning again, or playing them. A Swiffer duster does a good job at removing plain dust, or the Endust dry dusting cloths. I don't see the point of making mud for no good reason, which keeps the surface wet longer. Your mileage may vary...

I clean mine with soap and water, and I do it fast. To aid in this, I use a nylon scrubbing brush. If you place the 78 on a well supported flat surface (the draining area beside my stainless steel kitchen sink is perfect) you can really scrub hard and quickly.

I seem to get a lot of 78s covered in a sticky film, which I suspect is tar and nicotene from a previous owner's cigarette smoking. These need a hard scrub. I cannot detect ANY damage from the stiff nylon bristles in the scrubbing brush, and the 78s come up nice and shiny.

Keep labels as dry as possible as they can wrinkle and even come off. If you care about the little paper stamps on some 78s, be VERY careful as they come of easiest of all.

Good video. Almost identical to what I do, but for a really dirty 78, you'll need to scrub it a lot harder. I also keep the label a bit drier by not immersing the 78. Instead I use a soft paintbrush to brush the soapy water around the record, trying to avoid the label.

There's a movie called "Desperate Man Blues", It's a Great Documentary about an american record collector of Jazz, Country and Hillbilly music. He possibly has the best 78 collection of its type on earth.

One of the DVD extra's is "How to clean 78's" I like to show this to my OC friends to freak them out.

He basically vigorously scrubs his 78's with an old stiff wooden laundry brush and soapy water.

I don't necessarily claim this is the best method, but, he's a serious enthusiast and it obviously works for him.

[smee4]

I do this too. Except mine is a modern plastic equivalent brush - not wooden.
