What is the best way to clean Vinyl?

I currently am using a very old (mid 80's discwasher D4 System.  

Opinions?

Again, I'd like to thank everyone for their advice you've been very helpful.

I'm open to more suggestions.

TBS some of them definitely need work.

TIA

I’ve experimented with these fluids

Mobile Fidelity Record Wash

Spin Clean Fluid

Nitty Gritty Fluid

Keith Monks discOvery fluid

L'Art du Son Fluid

Record Doctor

VPI Fluid

They all work but I’ve found the disOvery fluid has the blackest background followed by L’Art du Son. But the L’Art must be kept in the refrigerator once opened. Yes the discOvery is a bit more $$ but IMO does the best overall cleaning job for new or used LPs.

What would be a good combination of Spin Clean, US. and vacuum machine for under $500?
