[Shop-talk] Cleaning an oil tank

[Doug Armstrong]

If you are able to break it up into pieces, you may want to consider hiring
a local dry-ice blasting company.

It has been used to remove sound deadening insulation in cars.

It will also not work against sludge.  it might kill some of the microbes
that are present, but it will not penetrate into the sludge, and it won't do
much for the actual sludge.  It will also generate large quantities of water
contaminated with diesel, which can't be
dumped on the ground or down a drain.   Mechanical removal is the only
real solution for that, either by reaching in and scooping it out, using a
vacuum, or breaking it up with agitation (put a piece of chain in and
shaking works well), and pumping it out with the fuel (through filters,
obviously.)
