Using Automotive Antifreeze in Black Grey Water Drains

I didn't even bother to read everyone else's post on this topic! The answer is "NO!" Don't do it. It probably will not hurt anything on your camper, but when and were you dump it can cause a lot of damage for someone else (be that the city sewer treatment plant or your own septic tank). Dump it on the ground, and every small critter, pet, and bird in your location will be dead from licking it off the ground. REALLY a bad idea! don't do it.
