Mike just done similar recently
We got called out to one over the easter weekend, lad had come back to the hotel p*ssed out of his head, sh!t himself all over the bed, mattress, carpet and lino. He had then went and run the bath to try and get it all cleaned up and promptly fallen asleep!!!
We got a call at 9 am in the morning when the cleaners had arrived to clean the bar area and public toilets to find them swimming in water and half the ceiling down!!
Anyway, we just binned all the soft furnishings in the room including the mattress, bedding, carpet, underlay and lino, I have never had much success with getting stains out of mattresses and I wasn't about to persevere with this one!
The insurance company gave us the whole job to do, finally finished it yesterday with a final coat of paint on the ceiling and a clean of the bar carpet, just got to work out the bill now!
