I keep my castnets in my pickup tool box. I had a quart of oil spill in the toolbox and it got all over my castnets. I soaked them for 30 minutes in a mixture of purple power degreaser and water 50/50 and it got the majority of it off. I am soaking them again right now and I am wondering if I could do something else to get the oil off of them. I don't believe that baitfish will taste too good with oil on them and it is not too good for the environment to use an oil soaked net. If I have to toss them I will but they were expensive.
