Man, I wish I did this sooner. I did the same thing on my lx 470, so I decided to love on my lx570 driver side front belt.
I unbolted the seatbelt from the b pillar. Easy access, and I believe I used a 14 mm ratchet. The belt was nasty, so I hit it with some shout stain remover.
I then used a power washer to hit both sides of the belt. Used a yellow tip, which is lower power than a red nozzle.
All told, I invested 20 minutes and my driver side belt looks damn near new.
