For which type of surface is a Category C cleaning method appropriate?

A Category C cleaning method is appropriate for ceramic tile surfaces because this type of surface is generally non-porous and can withstand more intense cleaning procedures. Category C cleaning methods involve the use of more aggressive cleaning agents or techniques, suitable for surfaces that are not sensitive to scrubbing or chemical exposure.

Ceramic tiles are typically durable and resistant to moisture, making them less likely to be damaged during the cleaning process, even when more potent cleaning solutions are employed. This resilience allows for effective removal of contaminants without compromising the integrity of the tile surface.

In contrast, other materials like wood trim or MDF are more sensitive to moisture and strong chemicals. Wood can warp, crack, or discolor with improper cleaning methods, and MDF, being made from compressed wood fibers, can swell or deteriorate if exposed to excessive moisture or harsh substances. Textured ceilings may have finishes that could be ruined by aggressive cleaning, making them unsuitable for Category C methods. Therefore, ceramic tile stands out as the most appropriate surface for this cleaning category.
