I used some vinyl cleaning product for my very first 78 and that was a disaster, obviously !

Though, the sound quality did not much deteriorate.
It's a dub, and I bought an original Brunswick copy since.

Now, I do mostly like Scrough: I use water with a small drop of washing up liquid (avoid too much foam !), and I rub the record with a sponge following the grooves (unlike what Bussard does on his video), then I rinse, I use a paint brush, and rinse again, but I dry the record immediately with a microfiber fabric, as I had pretty bad experiences when I let the records dry by themselves on a plate rack.
Works pretty well for me, and I can play my records pretty quickly after the cleaning.

I've done as Scrough described, adopting the procedure from cleaning LPs
Be careful only to do this on the traditional shellac with chalk filler type of 78 or any type of vinyl. Early construction techniques during the experimental period often used materials which would be destroyed by water, such as shellac with wood flour filler. Meths or isopropanol dried off quickly could be safe-ish, but preferably avoid contact with any fluid.
