I want to ask Is it good to use oven cleaning sprays to clean oven. Does the quality of the food baked in an oven will not goes down or become unhealthy?
It is safe
If you use it properly and follow the instructions.
When I clean my oven with those products, I make certain it is well wiped cleaned with clean water after and I will let the oven run empty for a little to make certain that if there's some left over product, it will be evaporated.
