When should chemical cleaning methods be used over mechanical methods?

Chemical cleaning methods are particularly advantageous when dealing with delicate surfaces or deep contaminants. This is because chemical agents can effectively penetrate and dissolve contaminants without the abrasive action that mechanical methods typically involve. Delicate surfaces, such as those made of softer materials or intricate designs, might be damaged by scrubbing or other mechanical processes. Therefore, chemical cleaning allows for a more thorough cleaning solution in these situations while minimizing the risk of physical damage.

Additionally, chemical cleaning can reach deep-seated contaminants that mechanical methods might struggle to remove, especially if the contaminants are lodged within textures or porous materials. The effectiveness of chemical solutions in such scenarios ensures that cleaning is comprehensive while maintaining the integrity of the surface being treated.
