Polisher & Extractor Equipment Flashcards

When a rotary polisher creates 'holograms' or 'buffer trails' on dark paint, what is the most likely cause?

Answer: Finishing with a heavy cutting pad and compound without a finishing step

Holograms are micro-scratches left by aggressive pads/compounds that must be refined with a finishing polish and softer pad.

What is the recommended water temperature range for a hot water extractor when cleaning automotive carpets?

Answer: 150–200°F

150–200°F is effective for breaking down soils and sanitizing without damaging carpet fibers or adhesives.

A polishing pad with a closed-cell foam construction is best suited for which task?

Answer: Applying wax or sealant as a finishing step

Closed-cell foam is dense and non-abrasive, making it ideal for applying and leveling wax or sealant without marring.

What does 'RPM' measure on a rotary polisher, and why does it matter for paint correction?

Answer: Revolutions per minute; higher RPM increases friction and heat generation

RPM measures how fast the pad spins, and higher RPM increases cutting aggressiveness and heat — requiring careful control.

Which extractor accessory is specifically designed to clean and extract moisture from automotive seats and tight crevices?

Answer: Detail upholstery tool with narrow slot nozzle

Narrow slot upholstery tools allow precise cleaning and moisture extraction in seat seams, bolsters, and tight interior spaces.

When using a DA polisher on a hood with multiple layers of paint oxidation, which pad choice is most appropriate for the correction stage?

Answer: White or red heavy-cut wool pad

Heavily oxidized paint requires an aggressive cutting pad (wool or heavy foam) to remove the damaged clear coat layer efficiently.

What safety precaution should be taken before servicing or changing pads on an electric polisher?

Answer: Unplug the machine from the power source completely

The machine must be fully unplugged before any pad changes to prevent accidental activation during servicing.
