Head cleaning
Audio and video tape players (ie. cassette players, VCRs) require regular maintenance to perform properly. Particles that come off the magnetic tape (ie. compact cassette, videocassette) can build up on the magnetic record/playback heads, reducing the signal quality. Head cleaning may be done with a special cloth or special long swabs and/or a cleaning tape/cassette. This removes smudges and dirt on the recording head.
Cotton threads can snag the heads, so cotton balls and swabs 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 due to damage to the ozone layer).
- Alcohols are effective for cleaning heads and guide rollers. Usually isopropyl alcohol or rubbing alcohol.
- Acetone is an effective solvent, but can damage plastics.
- Amyl nitrite and other nitrites are marketed as video head cleaners.
- Xylene is an effective solvent, but can damage plastics.
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.
Other uses
In some countries, to evade anti-drug laws, poppers like Amyl nitrite are labelled and/or packaged as tape head cleaner.
