Hi Lee,
What area have you set aside for cleaning the main body of mattresses and how have you kitted it out?
Our concern is that we would need a dedicated area for this exercise and a lot of stainless steel work-tops. Some mattresses, once the covers have been punctured and body fluids have got in, are somewhat... ripe.
Our Mop Laundry will be able to wash the covers.
Cheers
