Newty, I've had Stanley Steamer do the boat
They did a good job. Recently purchased a little green by bissell, it works well, heat and cleans at the same time. You can bring the carpet back a bit. You are more than welcome to borrow it anytime. It's in my garage.
Diggs is good at using the pressure washer. He is also very good with the shop vac to make the carpet stand up when she's dry. Good luck!
