Hi Colley,
I think this is something you should definitely pursue, there are huge openings for people in this field in the Uk, my company supply eco friendly Degreaser & Deep Cleaning Pads to many contractors in this field.
There are a lot of people in this field who actually dont know how to clean stainless steel properly, they use caustic & corrosive degreasers and sanitisers that cause detrimental damage to surfaces. Many of the start up guys that I supply have gone from strength to strength and made a lot money. When kitchen staff/head chefs see exactly what you can do and how it should be cleaned they are eating out of your hand.
If you need any help just let me know
