Hi TCS,
There are all-natural and/or biodegradable lubes that are better for the environment: Green Oil's Wet Lube, Pedro's Slick Wax, Eco Sheep.
Good point. On the ZFC site the Efeeto Mariposa Flowerpower rates as one of the most effective drip-on waxes, and the company says it has low environmental impact. And in bulk, the cost looks pretty reasonable.
Thanks and good health, Weogo
