For very stubborn deposits you can wash the inside of the tub with a solution made of household ammonia and mild detergent.
Ammonia in washing machine. 1 ounce of detergent. You do not use Ammonia in a washing machine. Bliss for about 2 weeks.
These cleaning solutions contain ammonium hydroxide a solution which is corrosive in nature. Ammonia is a versatile laundry additive vanquishing stains and dissolving grease as well as whitening whites and softening your bath towels. In the 1980s I was an EMT for a near west suburb of Chicago.
Ive used it for years in laundry as well but just remember to get regular non-sudsy ammonia the sudsy version will swamp an HE machine. Theres nothing more to do. Ammonia is an effective cleaning agent.
Is ammonia safe for washing clothes. Disintegrate sweat stains by adding undiluted ammonia to the stain with a cloth or rag. But seriously Ammonia is corrosive so dont use it in a machine.
Ammonia works great on oily soils and helps lift the body oils in work-out clothes sheets etc. 2 cups of water. The odor decreased a lot but still needs more so that it smells fresh.
Do not use this to wash your towels or heavy sweaters since it can destroy them. Dear Margaret I have a set of your leaflets on environmentally friendly lifestyles in which you suggest using ammonia rather than washing soda for laundry cleaning. So in this mornings wash load mainly towels.
