The hierarchy of alcohols begins with methanol, the most volatile and poisonous, C H3 OH, ethanol C2 H5 OH, then Isopropyl alcohol C3 H7 OH.
Methylated spirits sounds like it's methanol but is ethanol adulterated with methanol plus an emetic and in the UK some dye. In France you can buy it in supermarkets in 1 litre bottles, 90%, as alcohol a bruler, they don't add the dye. Used in Meths stoves and the like. I normally get a bottle or 2 if I go (by car) for general woodwork and cleaning use. Cheaper than Meths in the UK but the main reason I get it is the un-purpleness.
You can easily buy Isopropanol in the UK, as others have said. The pharmaceutical stuff often used the old name Surgical Spirit, I think you can get some horse rubbing stuff as well but I've never needed to rub a horse. The main marketing is as an electrical contact cleaner. I think the retail stuff is about 95%, no dye so very similar to the evergreen strength. It won't be quite as volatile as ethanol but I suspect it will be fine. During covid, DIY hand sanitiser with a mix of Isopropanol, water and a detergent served me well, and I use a 30/70 mix in a little bottle as a screen cleaner.
So maybe try Isopropanol?
