Not that I really care about chain maintenance anymore since I have a belt, but allow me to go off on a tangent for a bit here. This is what kills me about being a professional mechanic.
So this list...
I know the majority of people servicing their chain at home probably do one on this list. If I do any one of those and get caught, my shop is looking at a massive fine. Not parking ticket kinda fine either. Well into five figures. Plus we may be charged for cleanup/containment costs if the city drains are involved.
You wash your car at home? Or even worse, degrease the engine? That shit can go right to the storm drain in most situations. If it's done in any kind of professional situation, all kinds of traps and reclamation systems need to be in place. And if we get caught without it, massive fines that could shutter the business.
I could go on and on about how the little guy gets away with murder (don't get me started on A/C), but I'm sure most of you couldn't give a shit about the costs of doing business and would rather just whine about how much shops charge. Just know that everything on that list is not ok for me at a shop for a reason. It shouldn't be ok for you all at home either, no matter how insignificant you think your impact to the environment is. If the government thought they had even the slightest chance of being able to enforce and collect massive fines from individuals as well as high waste producing businesses, they absolutely would.
