I use a mix of isoprophylic alcohol, destilled water and dishwash. For heavy cleaning I use 1/4 alcohol, 3/4 destilled water and 2-3 drops of dishwasher fluid, cleaning with a microfiber brush or cloth, and drying with a soft cotton cloth, for daily use a record cleaner microfiber brush moistered with destilled water with a drop of dishwasher fluid.
With care, doing heavy cleaning, working in circular motion around the label you will keep it dry and as it were.
A new record comes with a sort of oil or grease on it and will have to be cleaned before use, the oil attached is used in the production to get the pressing tool to release the record, its kept on the record as protection. The oil will mute the sound a little, but the difference is only audible for very good or Crooked ears (Peter), when cleaning a new record, with the microfiber brush, normaly before playing, it will disappear after 3-4 plays anyway.
This works for me, but audiophiles will disagree, you can invest in machines to do this, but the end line is the cleaning liquid, which is more or less like my mix, the dishdrops provide the antistatic, but in very dry ambients you will have to use more sofisticated tools for this.
You can make everything into a science its only a question of how much you want to spend.
For cleaning my pickup needle, I use for daily cleaning a soft nylon brush, and once in a while I wet it with alcohol and brush it dry with the brush, all very carefully and softly, working back to front with the brush.
