During my quest to find something to deeeeeep clean a PF, I came across this post by @habo.
".... For really ground in playfield dirt and grime I use Westley’s Bleche-wite. Its main use is a tire white wall and lettering cleaner but it can be safely used on late model pins that are diamond plated or clear coated. Apply to small portions of a playfield at a time for about 10 seconds then gently brush the area. Once you’re finished, re-wipe the playfield with a damp cloth to make sure the cleaner is entirely off.
Here is a HS2 I did for Funhouse Amusements a few years ago. Really dirty."

OMG! Deja vu for you... I know this post is feeding off of an old thread but I recently got my hands on an HS2 that I believe was a HUO machine for most its life. Its PF looks almost EXACTLY as bad as the one you cleaned in the link above. I was looking for some advice to restore such a filthy field; unfortunately most cleaning blogs, vlogs and posts are for machines that get loved somewhat regularly, so this is a literal spot-on link for me! My machine has so much dirt I considered a rototiller to start the process. I'm Probably gonna remove most, but not all hardware to get down deeper but my skill lvl and patience is limited so I fear creating a situation where I have to pay for tech to fix my goofs. Game has a few other issues to fix but no serious problems. Maybe I'll try to do some regular updates and pics as I go along but will certainly post more before/after pics when complete. Pics below are taken through glass as you may suspect.
