I've waited years for stumps to rot in places that they are not
unsightly but you don't have that much time. The best suggestion I
think you got when you mentioned pressure washer was to use it to wash
away the grit around the base of the stump and maybe a few inches
further. Then you can use your chainsaw without getting the rapid
dulling if you cut into gritty soil. Lot cheaper to resharpen a chain
saw than rent a stump grinder.

I had a stump pulled from the ground in recent years. A 10 ton dump
truck, a couple workers to connect chains and yank it out. OP may not
have that access to the stump.
