No, it's OK Wojtek. White Spirit is sold (In the UK anyway) as 'Turpentine Substitute'. It's an oil based thinners, basically enamel thinners! It's clear, like water, and has that typical thinners smell. I've been using it for at least 30 years!
Of course, it won't work with acrylics, but is fine with all modelling enamels, and household 'decorating' paints, as that's what it's designed for. I used to get mine for free from a painter and decorator friend, but he's now moved, so I have to buy it! But at only around £3, maybe a bit more, for 2.5 litres, I don't mind!
