Cleaning Cassette Decks


I have a Nakamichi DR1 cassette deck and I plan on recording some of my favorite vinyl for easy playback. It sounds wonderfull and maintaines the warmth and liquidity of my vinyl. I want to make sure I maintain it as well. Any advice on cleaners, technics, for heads, pinch rollers, other. I want to keep it in good shape. Also, anyone have any experience with the Nakamichi DM10 demagnetizer. thanks.

Denatured isopropyl alcohol. Rubbing alcohol has water in it and can cause the laminations of the head to rust. Yes you can use alcohol on the capstan and pinch roller. Be careful not to get things to wet. The Q-Tip only needs to be moist not dripping wet. You do not want to get the alcohol in the capstan shaft bearings, or the pinch roller bushing.

The DM10, "Turn the deck off. Turn the demaganetizer on and slowly", underlined, "bring the tip as close as possible to the record/play head {it is not necessary to demagnetize the erase head}. Do not make contact with the head unless the tip of the demagnetizer is covered with thin vinyl or rubber to avoid scratching the surface of the head. Move the demagnetizer tip slowly",underlined, "in a random pattern about the surface of the head for at least 10 seconds and then slowly", underlined, "move it toward the capstan. Repeat with the capstan, and then slowly", underlined, "withdraw the demagnetizer. Turn it off after it is at least 2 feet from the deck. Never turn the demagnetizer off while it is close to the head or capstan as this may semi-permanently magnetize the metal part"
If the rollers are rubber instead of a synthetic material alcohol is not recommended as it will dry out rolers. It is safer to use a mild (diluted) soapy solution on rollers.
I seem to remember, way back in the dim recesses of my mind, that certain cassette deck heads used plastic, and although isopropyl may be appropriate for reel to reel decks, it may harm the cassette deck heads. But I could be thinking of Carbon Tet. [Carbona].... back in the days when you could get kick ass solvents. Maybe the fumes just got to me over the years!!

But does anyone remember if cassette deck heads have to be cleaned with different solvents than reel to reel heads?
A very excellent product is Professional Audio Tape Head Cleaning Fluid from American Recorder Technologies, S-721H. It is non-alcohol and recommended for tape heads, guides, capstans and pinch rollers:
