What cleaner to dissolve oil?

You can get hotter water by upping the temperature of the thermostat in your hot water heater. It's probably set to between 120 and 140f now. Just crank it up to maximum, do you cleaning job and then reset it back where it was.

this I would not do... a hot water tank can be come a rocket. that is to close to boiling point.

best to get large tub build a fire under it and dip and pour...

my grandmother used to boil water in a wash tub then transfer it to other things..


much easier and safer.

I don't believe a hot water heater thermostat can be cranked high enough to boil. The maximum is probably around 150-160f. Unsafe for a shower but certainly not rocket fuel potential.

google hot water heater failures... one on a naval base went through three floors plus the roof.. and destroyed another roof.

If setting a thermostat to the maximum setting caused a failure in an otherwise good condition water heater, the lawyers would be having a field day with it, don't you think?

Most commercial water heaters use a boiler to heat the water

Jack in my area there are people who rent steam cleaners sort of like the car wash... it is hot enough to take grease off of trucks. you might want to check into that.

Or, take them to car wash and do it in the bay. Use what ever chemicals you want. People wash all kinds of stuff out in those things. Engines with gunk degreaser included.

Gerald,

who would be left to tell us corny jokes :-)

I resemble that remark!

How ever you clean the tanks, what are you planning on doing with the waste?

You can't just dump this stuff in the back yard so a bit of care needs to be given to the plan.

I think it is best to contact the car wash owner to find out what waste capture system he has. I can tell you that a local boat yard got into a lot of trouble and big fines because one of his yahoo boat owners did his own maintenance and wet sanded a boat bottom dumping the paint onto the ground and then washed it into the ocean...

best we think about this....

Around here the car washes have a setting for degreasing engines and they have a grease trap in their system.
