What are the components of the banana peelings that can be used as shoe polisher?
Banana peelings contain a lot of minerals ( potassium, calcium, magnesium, silicic acid ), sugar, starch, proteins fat, tannic acid, colouring agents, phenyl-alkyl-amines and and and.
The agents making your shoes shiny and soft are fat and tannic acid.
You can also use the peelings as nutrient for plants liking potassium ( roses p.e. ) and to make ink ( boiling peelings and iron-nails in water and some vinegar: the tannic acid reacts with the iron%26gt; black coloured solution ).
