Well it is only a RU-vid Short. I was mainly highlighting the mounting in my sprinter van. I can do a longer vid and review my setup but I’m waiting to see how it does.
This was when I first got everything setup. But my tools at work stay cleaner than at home because I work in the new oem truck business so everything is clean there lol
Could be he just cleans them regularly. I do a quick wipe down with a lightly damp rag after every use, everything stays looking brand new. Just don't let it build up and it's easy to clean. And for any buildup I use Tub o' Towels. They're a godsend
