What is the proper first cleaning agent for preparing a plastic panel?

• A. Acetone
• B. Soap and Water
• C. Gasoline
• D. Alcohol

Answer: (B)

Cleaning first with soap and water is about starting with the gentlest, most effective option to remove dirt, dust, and surface oils without risking damage to the plastic. This initial wash helps ensure contaminants won’t interfere with adhesion or coatings later on, and it won’t soften or craze the plastic like harsher solvents can. Acetone can dissolve or warp many plastics, making it risky for a plastic panel. Gasoline is not only hazardous to handle and highly flammable, but it can also damage the material and leave residues. Alcohol can remove some residues, but it may not lift heavy grease as reliably as soap and water and can affect certain finishes. So, soap and water is the best first cleaning step to prepare a plastic panel.
