While it is not completely harmless as an ingredient for use in the house, the ammonia is much less aggressive than many synthetic cleaners offered in the markets. They contain toxic chemicals and have poisonous vapors. If you use natural ingredients to clean the surface and remove bacteria, such as baking soda and vinegar, you can use ammonia for more stubborn dirt. Note however, that the ingredient can cause asthma. Never mix ammonia with bleach or chlorine, because it would create poisonous fumes.
Clean the surfaces of the electric oven quickly and easily by using a small quantity ammonia. All you have to do is to heat the oven to 65 degrees and after that you have to turn it off. You should leave a small bowl of ammonia in it on the higher level at the oven and below you need to place a bowl of boiling water. Then close the oven and do not open it till the next day. On the next morning open the oven, remove the two bowls and allow it to ventilate. You will clean every inch of the oven with a cloth which is soaked in the ammonia. Next thing you will do is wiping with a solution of dish soap in warm water. You have to use a clean cloth for that purpose. The oven should dry completely. It is of great significance to use the method described only for electric ovens, not for ovens that run on gas. Movable parts of the oven can be cleaned by soaking them in a bath in which you mixed warm water and half a cup of ammonia. Leave them to stay in this solution for 20 minutes and then wipe them with a cloth.
