The other day, I grabbed my worst pair of welding gloves and used those to grab the bulk of the chips.
When I got down to the small, oily chips (my CF is oil), I used a whisk to whisk everything over to where the drain is. As the CF slowly drained, my still gloved hands removed maximum chips with minimum CF.
This was messy and took a long time, but the results were great. This is what I will continue to do until I can afford to implement one of the ideas in this thread.
Interesting sidenote: our garbage can that goes out on the curb has a crack in it & there are oily CF puddles where we store the garbage can & on the street. My wife was not too pleased with this development as I was also blamed for causing the crack in the garbage can “when I threw some big piece of metal in there”.
