the first US Lakland that I got had obviously been abused. It was scratched (3TB), partly discolored, the figured BEM (2001) fretboard worn to gray in some places, the back of the neck had a distinct place where the bass was had been leaned onto something - part of the neck from that point on was darker. The hardware rusted and dirty, the knobs barely moved, the passive mode switch wouldn't pull out. In one word, OUCH!
I don't have all the pics of the original condition, but that's part of it:

note the difference of the bridges of the 2 Lakies.
So I took mineral spirits (on Lakland's advice), pure orange oil without solvent, WD40 for metal parts, some cloth. The idea from the start was that I would not restore it to the 'as new' condition, but rather to have a worn bass. I could easily have buffed and even refinished the wood and refinished the chrome on the metal parts but chose not to, only thoroughly brushed away the dirt and removed part of the rust that needed not to be. The hardest point was the neck, which, as you may see, was very dirty, and I also wanted to bring up the beauty of the wood. That, I must admit, I achieved but partly.
So I have a great working horse (current state not pictured) which looks like a 70-ies 'closet treasure'. Trust me, it's clean, oiled, treated, but looks worn, has all the scratches, discolorations and touches of oxidation. I still can make it look 'newer' but I won't. The only part that I regret is the fretboard, but this I may yet come to.
I wouldn't do all that wear myself but I like how it looks now
