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.
