Hot water is a god thing but be careful.

Check your pressure washer manual before trying the hot water tank trick.

Some PW pumps cannot handle elevated inlet temperatures.

Also make sure your supply hose is in good shape, the hose will soften and expand under high temperatures and might let go on you.

Better idea if you have a car wash close by:
- acquire set of Tyvek coveralls
- put ramps in trunk along with the pump sprayer
- get a roll of quarters
- go to self serve car wash
- put ramps in bay and raise up car
- soak - n - spray

Their hot water supply is much larger than yours and also they have waste treatment for the runoff water. And the runoff won't kill your lawn or worse your wife's flowers.
