Invest in a Groovmaster (approx. $50 on Amazon), which protects the labels, and then do whatever you feel comfortable with per to your budget.
I mix my own cleaning fluid and use filtered tap water with super results.
What I do not do is apply a brush/cloth et cetera until a "dirty" LP has been thoroughly flushed with warm water (I use an old WaterPik to pressure wash them) and then I use a basic DIY cleaning solution and a brush.
Applying a brush without this step simply grinds any foreign matter present into the LP.
Therefore, you can have a $5K super duper RCM and end up damaging "dirty" LP's when following the operational instructions.
It's really just simple common sense.
