Took just over one hour. Mike was punctual and enthusiastic. He communicated well, while getting on with the job in hand.
The result was splendid, and a lovely surprise for my wife when she came home from town.
We have cleaned this oven and its parts ourselves previously, but the outcome using an experienced professional cleaner and the appropriate professional grade chemicals and equipment was both better – and easier for us!
We are getting a bit too old to tackle this work ourselves, and will use OvenKing again.
