I'm so cross. DH has cooked multiple times in the ninja without cleaning between and it's now got dried on tiny spots of grease. I've tried pink stuff and a scrub daddy. Any other ideas to get it off? I can get some off if I scrape with my nail but it's not ideal and it hurts ! He can't be trusted with baking trays either as leaves in oven after cooking while hot rather than quickly washing while grease is soft
