This is what I've settled on after many years and many ways:
1. wipe the outside of the record jacket with a clean microfibre cloth
2. take the record out and discard the inner sleeve
3. with a clean microfibre cloth gently dry wipe both sides of the record
4. Wash Cycle: place the record in a 5 minute cycle US bath at 35 degrees C (distilled water, isopropyl alcohol, and Triton X100 surfactant)
5. Rinse Cycle: then place it in another 5 minute cycle US bath at 35 degrees C (same solution as Step 4 without but WITHOUT the alcohol)
6. Vacuum Cycle: then use a record vacuum cleaner to clean each sides. I apply distilled water/Triton X100 (same as Step 5 solution) and spread that with a brush, then vacuum it off. Both sides.
7. then I let it air dry for at least 20 minutes before placing it in a new rice paper antistatic inner sleeve
8. then back into the jacket and a new outer sleeve.
The cost is reasonable since i make my own solutions, and I bought my two US machines off eBay. I got the motorized Project vacuum cleaner that turns by itself.
I change the solutions when they become too dirty (I check it visually and also use a turbidimeter).
Oh and I clean the stylus with Magic Eraser before every side. And if i see lint on a record, I use Tiger Cloth since it's the least staticy fabric I've come across.
I no longer use record brushes, nor do I use liquid cleaners or gels for the stylus anymore.
Everyone's method and tools differ. I may change this method too if I come across a good alternative, or if new equipment dictates a change (e.g. I probably won't use Magic Eraser on the new optical cartridge (DS Audio).
