What Would You Use?

Had an oil tank leak in back compartment. Need to get it cleaned up.
Thanks

baking soda or oil sorb then vacuum is what I would try first. If it's in carpet then simple green or dawn soap and scrub brush. Someone else my have something better to use. Good luck.

Shop vac worked for me, had a gallon jug full lid rattled off and tipped over in the back. Had to replace the vac filter after it though. But cleaned up nicely

Simple Green, spray on everything and let it sit for a few minutes and then wash it out. I am assuming it in in the bilge area so pull the plug and let it drain out. Repeat if needed.

Afterward throw a bar of LAVA soap in the bilge area. With what little water gets in there it keeps everything clean.
