Ultrasonic & Ozone Content Cleaning Flashcards

What is the primary purpose of creating a detailed content inventory before pack-out and cleaning begins?

Answer: To document pre-existing damage and establish a chain of custody

A pre-cleaning inventory with photographs documents the pre-loss condition and maintains chain of custody, protecting both the restorer and the property owner from disputes.

Which type of smoke residue typically requires the most intensive ultrasonic cleaning cycles in a restoration scenario?

Answer: Synthetic or plastic fire smoke

Synthetic plastic smoke contains complex hydrocarbon chains and chemical byproducts that are more chemically resistant and require longer cycles and appropriate solvents.

A restorer encounters antique porcelain figurines with gilt decoration and heavy smoke damage. What is the most appropriate first step?

Answer: Spot-test an inconspicuous area with the chosen method before proceeding

Testing on an inconspicuous area is mandatory for antiques because old repairs, over-glazed decoration, or unstable gilding can be destroyed by ultrasonic or chemical cleaning.

When should contents undergo pre-cleaning before being placed into the ultrasonic tank?

Answer: Whenever heavy debris or loose contamination is present that could clog or contaminate the tank

Pre-cleaning removes bulk debris that would rapidly contaminate the tank solution, reducing effectiveness and risking cross-contamination of other items.

What documentation must accompany packed-out contents transported to an off-site cleaning facility?

Answer: A detailed inventory with photographs, condition notes, and signed chain-of-custody forms

Comprehensive documentation protects all parties during transport and processing, supporting the insurance claim and preventing disputes about item condition or loss.

Which category of items is best suited for ozone treatment rather than ultrasonic immersion cleaning after a fire?

Answer: Soft goods, books, and other porous items that cannot be safely immersed

Ozone is ideal for porous, water-sensitive items like textiles and books that would be damaged by immersion but still carry embedded smoke odors.

What is the correct action when the ultrasonic tank solution becomes heavily contaminated partway through a large restoration job?

Answer: Change the solution completely and dispose of the contaminated fluid per local regulations

Contaminated solution loses cleaning effectiveness and can re-deposit dissolved soils back onto items, so complete replacement and proper disposal are required.
