IICRC Fire and Smoke Restoration Technician (FSRT) Practice Exam

Cleaning fiberglass fixtures is most effectively achieved with a crème compound due to its viscosity and ability to adhere to surfaces while providing sufficient scrubbing action. Crème compounds possess a thick consistency that allows them to cling to vertical surfaces, which is particularly beneficial when dealing with fiberglass fixtures that may require a more controlled application of the cleaning agent. This consistency helps encapsulate dirt and grime, ensuring a more thorough clean without the risk of excess liquid dripping off and compromising the effectiveness of the cleaning process.

Additionally, crème compounds often contain mild abrasives, which help remove embedded stains or oxidation without scratching the fragile fiberglass surface. This preventive measure ensures that the integrity of the fiberglass is maintained while achieving a high level of cleanliness.

Other compounds such as powder, liquid, or gel types may not offer the same advantages. Powder compounds may require water to activate, which can lead to uneven application, while liquid compounds might run or drip, making it difficult to keep the solution in place during cleaning. Gel compounds, while thicker than liquids, may not always provide the same level of scrubbing capability or abrasion as crème compounds, which are designed specifically for effective surface cleaning.
