I know it has to do with acids and bases.

pigments is produced by molecules, such as beta carotene, that contain moieties (pieces) known as chromophores. Chemical bleaches work in one of two ways:

* An oxidizing bleach works by breaking the chemical bonds that make up the chromophore. This changes the molecule into a different substance that either does not contain a chromophore, or contains a chromophore that does not absorb visible light.

* A reducing bleach works by converting double bonds in the chromophore into single bonds. This eliminates the ability of the chromophore to absorb visible light.[1]

Sunlight acts as a bleach through a process leading to similar results: high energy photons of light, often in the violet or ultraviolet range, can disrupt the bonds in the chromophore, rendering the resulting substance colorless. [2]

vinegar: is acid. Will dissolve many materials that are basic that
plain water would not dissolve.

ammonia: is alkaline. Will react with organic acids to form soluble compounds.

By dissolving the crud is removed either directly into solution, or mechanical breakdown of just part of the crud allowing the rest to come off.

Bleach: oxidizing agent. Chemically reacts with stuff to oxidize it, causing it to go away or become colorless.

They are also known as organic solvents because of their chemical structure.
