Video head cleaner

A video head cleaner is a substance used for cleaning the record/playback heads of a video or audio cassette player.

Audio and video (VCR) cassette players require regular maintenance to perform properly. Particles that come off the magnetic tape from the videocassette can build up on the helical scan record/playback heads, reducing the signal quality. Head cleaning may be done with a special cloth or special long swabs and/or a cleaning cassette. This removes smudges and dirt on the recording head.

Cotton threads can snag the video heads, so cotton balls and swaps should not be used.

Cleaning fluids

Fluids used for cleaning video heads include (but are not limited to) the following solvents:

• Freon-Dichlorodifluoromethane (discontinued in 1995 for damage to the ozone layer).
• Alcohols are effective for cleaning heads and guide rollers.
• Acetone is an effective solvent, but can damage plastics.
• Amyl Nitrite and other nitrites are marketed as video head cleaners.

Dry cleaners

Dry methods of cleaning include:

• Compact Cassette-shaped devices that can be inserted into tape decks and played for a short time to polish the recording heads to remove smudges and dirt. This may shorten the life of the unit and should not be overused.
• Compact Cassette-shaped devices that have a cloth tape that can have liquid cleaning fluids added to it before being inserted into a tape deck and played for a short time.

Recreation

Video head cleaners are also used as a recreational drug: see Poppers.
