I used to be an Album Rock DJ in the day. The only time we needed to clean LP’s was when someone got food on them. And that happened a lot. When it would be a while before we could get a replacement from the record company, we used warm liquid dish detergent & cleaned gently with a tooth brush following the directions of the grooves. Then lightly rinse & gently dry.
Of course, for collectors you just have to keep the center label dry.
It hardly ever failed & didn’t scratch the LP.
We didnt clean them till they skipped from crud in the grooves.
I still have it, but I think the fluid has long since evaporated. I think it's in my closet next to my Discwasher DMAG cassette head demagnetizer.

That's is exactly what we did when I worked as a DJ in radio. Get them wet, then gently wipe with dish soap and a clean cloth. Then rinse and dry. Got rid of pops and crackles. Not good for a collectable record label, but we only cared about the sound on the air.
