If the government and multi-national companies are putting a veil on the truth just so they can make a steady profit out of the microwave business, then they are to be held accountable for the health hazards that people have been subjected to for years. Some studies have already proven that microwave heating can cause significant molecular changes in our food. Taking into account the efficiency of a microwave oven compared to a convection oven in terms of cooking food only makes the result more exponential. Hence, a University in Bristol came up with the exact figures after doing an experiment, coming up with a conclusion that microwaves save 30% energy over conventional ovens. Also keep it mind to rinse the sponge in steady intervals to wash away the dirt that would proliferate on the material. 7. Start scrubbing with the top portion of the interior so that you won't have to redo the bottom part due to fallen particles.
