Introduction:

What is best for removing stains, washing detergent or home solutions?

I decided to do this experiment to see which removal product works best. I started to think to think which stain removers I could use when I thought of what they did in the 1900s. They used home solutions. So I looked through Aunt Daisys book of handy hints and found the coffee stain remover and then my project had really begun.

Hypothesis:

My hypothesis is that the washing detergent will be better because the washing detergent might work better on dry stains. The home solution will probably not work as good.

Planning a fair test:

Unfortunately, I have to change two factors.
The two factors I am going to change are:

1.The type of stain remover:
Aunt Daisys stain remover
Surf Washing detergent

2.The recipes for:
The home solution recipe
The Washing detergent recipe


The factors I am going to keep are:

1. The size of the material
2. The type of material
3. The amount of coffee spilt on the material
4. The amount of time left to soak
5. The amount of time left to dry
6. The amount of water and Glycerine

Results:


The result were that the Surf was slightly better than the Glycerine.

Surf material:

Sight: The material was really close to having removed the stain completely.
Smell: The smell is completely gone.
Feel: The normal material is softer than it.

Glycerine material:


Sight: Looks like it is halfway from finishing.
Smell: Slight coffee smell.
Feel: It feels wet.


Conclusion:


My data tells me that Modern Technology (Surf) was better than the Old Solution (Glycerine). The Surf  
was slightly better than the Glycerine
