Mystery Stain Solved with Fertilizer Chemistry!

In summary, the conversation involves mixing fertilizer based on a soil test, which contains various chemicals including ammonium sulfate, potassium sulfate, superphosphate, manganese sulfate, and boric acid. After getting a stain on a white t-shirt, the person tries to remove it with various methods, eventually finding success with the addition of hydrogen peroxide. They then ask for ideas on why the rest of the laundry load turned beige and reddish brown, speculating that it may be due to the oxidation of manganese by bleach and the subsequent conversion back to a soluble form by peroxide.

I mixed some fertilizer based on a soil test. The chemistry contained Ammonium Sulfate prills (NH4)2SO4, Potassium Sulfate prills K2SO4, Superphosphate CaH4P2O8, trace of Manganese Sulfate MNS04, and trace of Boric Acid H3BO3.

I mixed it and wiped my hands on the front of a white tee shirt. It remained white. When washed today with tide and bleach NaClO, the front of the shirt turned dark brown and the rest of the sizeable laundry load, all whites, towels etc., turned a deep beige. We were unable to remove the stain which was more like a dye. finally guessing that the stain was some form of manganese I added some lemon juice to about the 4th or 5th try to get rid of the stain. Then added some Hydrogen Peroxide H2O2. The stain instantly dissappeared as soon as the H2O2 hit it.

A rewash with tide and a little bleach it did not come back. Any ideas what might have been the reaction that turned the whole load beige, reddish brown. There was no iron listed as an ingredient of any of the minerals used.

1. What is the mystery stain and how was it solved?

The mystery stain was a large, dark spot on a carpet that had been present for several weeks. It was solved by using knowledge of fertilizer chemistry, specifically the use of ammonium sulfate to break down the stain's components.

2. How does fertilizer chemistry play a role in solving the mystery stain?

Fertilizer chemistry involves the study of how different elements and compounds interact with each other. In this case, ammonium sulfate was able to break down the components of the stain and make it easier to remove.

3. What is ammonium sulfate and how does it work to remove stains?

Ammonium sulfate is a compound commonly used in fertilizers. It is highly soluble in water and can act as a drying agent, making it effective in breaking down and removing stains. It also has a high nitrogen content, which can help to neutralize acidic stains.

4. Are there any potential risks or side effects of using fertilizer chemistry to remove stains?

While ammonium sulfate is generally safe to use, it is important to follow proper safety precautions when handling it. This includes wearing gloves and protective eyewear. Additionally, it is important to properly dilute the fertilizer before using it to avoid any potential harm to surfaces or fabrics.

5. Can fertilizer chemistry be used to remove other types of stains?

Yes, fertilizer chemistry can be used to remove a variety of stains, including those caused by food, drinks, and even pet accidents. However, it is important to note that the effectiveness may vary depending on the type of stain and surface it is on. It is always best to test a small, inconspicuous area before using any cleaning solution on a larger area.
