We filmed this video this morning, when clients from a very large pet food manufacturer brought pieces of equipment like this very dirty ladder to put our Steam Box 220v to test. The dirt on the ladder is very heavily baked-on pet food, practically impossible to clean by hand or with a pressure washer. This ladder was one of the most dirty tool they could get to put our steam box steam cleaner to the test, see the results for yourself! We detailed and disinfected: blades and meat cutting tools, bins and teflon conveyor belt parts.Please visit https://dupray.com for more information about our commercial steam cleaners or to place an order.
