The vlog speaks for itself. Take one very greasy cooker with food baked onto it for good measure and rub all over with a damp scrubby sponge. Sprinkle with bicarb and rub - give it welly! When degreased, use an old cloth to rinse off, keep rinsing it out in the washing up bowl. All shiny and clean in three minutes! I think this beats watching paint dry, but only by a small margin............cooker cleaning!
