because white spirit is fizzy and contains carbon dioxide the carbon dioxide fights against the paint and wins whereas water tries to fight the paint and loses

Answer:

Paint gets dissolved into white spirit quite easily. Therefore paint is removed by white spirit

Explanation:

White spirit contains petroleum based hydrocarbons (mainly alicyclic hydrocarbons). Water is a polar inorganic molecule.

Paint is a mixture of different organic polymers like polyvinyl acetate, polyesters, polyurethane etc.

As per solubility rule, organic molecule prefers organic solvent to get dissolved into it. Same rule apply for inorganic molecules also.

There paint, being an organic molecule, prefers white spirit as a solvent rather than water.
