Quick way to clean an oven?

Baking Soda and Vinegar. Sprinkle Baking Soda on the worst spots and spray with vinegar and let it soak, it should wipe clean pretty easily.

Buy Self Cleaning Oven or Warm Oven and use Oven Cleaner or Cillit Bang or Mr Mussel

well, not to quick, but spray with oven cleaner, put in black plastic bag, leave out in sun for the day. late afternoon, take out of bag and hose off. most gunk will be off and the rest just goes with the hose.

Warm the oven to about 250. Sprinkle baking soda over floor of oven. Sprinkle on vinegar. Close the door while it all fizzes. Grab a few absorbant cloths and wipe out the oven after the fizzing stops. You might have to give a little elbow grease a go on any splatters on the sides.

thank you

My mother used to put a small bowl or pan of Ammonia in a warm oven... let it set about an hour and then wipe it down with hot water and vinegar.

BUT... sadly... unless you have a self-cleaning oven... and if the oven is not very dirty.... there really is not a QUICK way to clean it.... it still takes time for the cleaning agent to work... and elbow grease to finish it off
