We sanitize our own 12,000 sq ft building every week, its sprayed down with some kind of acidic mix of crap. Think the mixture is like $20....but I work at a Government facility so maybe they get a discount.
Back during the anthrax attack hoopla USPS bleached the crap out of everything. Hundreds of hours were wasted cleaning clean machines. Just look at how some people wear their masks. A whole other thread on that.
