I've looked in the Parish "Index", and then asked Prof Google, and can see several local firms claiming to clean all the accumulated gunk inside my oven to make it look "as good as new" (etc).
Has anybody had good experience from any of these and would recommend them?
You see, in the follow-up to international women's day on Monday I wanted to show that I wasn't inferior to women in cleaning ovens, but it defeated me in the end and I thought I'd get professional help.
