Is it better on some paints or finishes?
Being the softest buffing cloth we do makes it perfect for dark coloured cars, soft finishes or wraps/PPF that may suffer from swirls more readily than other types of finish.
Does it work on glass?
It’s better for paint, but can be used on glass too - it just won't be so good at removing smears as a waffle weave microfibre or more aggressive short pile cloth.
How should I wash it?
Use a dedicated microfibre detergent like Dodo Juice Furry Liquid at 40 degrees (non-bio liquid will work but won't be as good) and never use fabric softener or conditioner as it will clog the fibres. After washing, tumble dry at lower temps to restore fluffiness.
