For what it's worth....
If the container has a drain in the bottom, place a couple of Lt's of water in the drum with the kero making sure it's below the pump pick up and leave it for a couple of days. As water is heavier than kero and it doesn't mix with the kero, it will separate and the crap that is held in the kero will fall out of suspension and sit in the water, not in your kero and the kero will last a last longer and stay cleaner. As there is a drain, you can drain the water off with the crap and dispose in a much more environmentally better means. The main trick with a bike parts cleaner is to not use it to clean your air filters. Oil filter oil contaminates parts washers in no time at all.
