Hi Guys
It all gets a bit blurred when using a TM because the temp dial says over 100 C at times, well over 232F

However by the time it exits the wand , probably about 90 so still hot water , just.
However if the custy asks for steam cleaning , they mean HWE, so no need to confuse them.
I have used the following phrase on leaflets, websites etc.
'we use the hot water extarction method, sometimes called steam cleaning'
Cheers
Doug
