Deep Cleaning Used Pond Pump & Filter

Bought secondhand pump/filter. Asks how to deep clean to avoid transferring viruses/bugs.

Effective Methods

Dry completely >4 hours. Aquatic parasites die without water.
White vinegar wipe: Damp cloth, scrub all surfaces. Highly acidic, kills pathogens. Rinse thoroughly before use.
Disassemble filter (remove screws) to access interior.

Bleach works but requires massive rinsing. Vinegar + dry time is safer, easier.
