    So here's the question. Cleaning tape heads and rollers.

    I normally use a high percentage isoprop, but I'm reading that some people use, "Denatured alcohol," and I believe that in the UK we know that as methylated spirits.

    Are the two the same thing and if so, why one over the other?

    Grateful for any insights.

    Hello I also use a high percentage isopropyl
    Denatured alcohol and isopropyl alcohol are two types of alcohol which differ from each other according to their nature of toxicity. The main difference between denatured alcohol and isopropyl alcohol is that denatured alcohol is composed of ethyl alcohol along with other chemical compounds whereas isopropyl alcohol is composed of only isopropyl alcohol molecules.
    additive chemicals can harm a human's skin methyl alcohol, also known as methanol.

    For my short time in the tape industry I used 92% (or more) IPA, the extra is water. I used to clean Otari Tape Loaders and also run cleaning tape loops for tape head wear analysis. IPA works great and didn't mess up the testing if specs were from potential client. I never used denatured alcohol and I'd look it up in chemical resistant charts before using it. The denatured alcohol might be for the rollers to get them softer.

    In the U.K. Methylated spirits is usually bright Purple. All the additives are only added to make undrinkable. Otherwise the Vodka manufacturers would go out of business.

    That sounds good, RadioRich .....

    Careful though, as some of those stronger solutions have adverse carcinogenic properties that are not good for our fingertips touch and lungs.

    Cheers,

    Bleusy
