The lack of hot water in the kitchen sinks has bothered me for a long time. My mother was a major germ-a-phobe, and I guess it rubbed off on me. So I wash everything very well with antibacterial dw soap, usually Dawn - which is easy to find. Now don't laugh, but after I wash the silverware I do pop them into a little pot of boiling water for a minute or two.
We just bought a portable dishwasher, on wheels, it hooks up to the kitchen sink faucet, and shipped it down via Embarque Bella Vista. It will heat the water while washing. Assuming I have electricity, I don't expect it to work on the inverter.
