    Question Cleaning recording heads with 70% isopropyl rubbing alcohol

    Sign in to disable this ad
    Hello,

    I just cleaned my TASCAM 414 recording heads and rollers with Q-Tips and 70% rubbing alcohol. I then read some posts about not doing that and only using much higher alcohol content like 98 or 99% alcohol or I risk damaging the heads! Ok I will do that BUT did I just damage my recording heads when I cleaned with the 70% solution that one time ? I just did that yesterday. Oh man .. I hope I didn't do any harm ...

    Thanks very much,

    Daniel

    The danger with the 70% is the lubricating additives they put in with it....

    The 70% is rubbing alcohol and is designed for use on human skin as a friction rub (hence the lubricating additives)

    I suggest you re-clean the heads carefully with the proper stuff (99% isopropyl)....

    Also, do not use ANY alcohol on the pinch roller - it will dry out the rubber - use the proper pinch roller cleaner....

    Markertek sells the rubber cleaner. $9.99 a bottle. Should last a four-track machine a lifetime.

    Thanks very much guys and I am gonna use the right stuff but can you perhaps answer if this one time cleaning, with the 70% solution, "damaged" the heads already ? I'm never going to do that again but am just wondering.

    Thanks again,

    Daniel

    Probably not... but there's no way to know without testing the heads with a scope...!

    If you don't notice any difference I'm sure it's fine...!

    According to my tech friend, 70 % can rust or corrode the heads on some machines.

    ...when done consistently over time I assume and not after one time ...

    Where you can get in trouble immediately is the film left on the heads can be transfered to the tape if you playback over the contamination.
