Removing frame etching

    Local plod made a mess of etching my frame.  I’m slightly miffed but can live with it, as it’s on the bottom of the downtube.  However, it makes my bike look stolen, like I’ve tried to remove the etching.

    I suspect I’m looking at covering it up with a sticker or something – unless anyone knows if it’s possible to remove it by chemical means, without muffing up the paint?

    Depending on how thick the paint coat is you may be able to polish off the marks down to clean paint then apply some clearcoat. 

    Failing that you are looking at a respray I fear.

    Sorry – should have been clearer – the marks I don’t want were made by the same substance.  The bloke who applied the number realised he’d cocked it up halfway through and tried to “rub off” the fluid (acid?).  He actually just spread it around a bit, so those marks are now etched into the paint.

    I always buy acetone in a small bottle from the local chemist (good for dealing with tubular tyre glue).  Don’t recall ever paying more than £4 for a bottle.  And a quick look on Amazon shows you can get 250ml for £3.24.

    No idea whether it will stand any chance of removing the marking on your frame though.

    Looks that way. On closer inspection, the marking isn’t a paint layer on the surface of the frame, it’s actually made up of small indentations – it has gone through the clear and the first layer of paint.

    Some nail polish removers

    Some nail polish removers contain a little acetone, but you wouldn’t want to use pure acetone on finger nails.  Your local(ish) hardware shop or a decorator’s store will sell expensive tins of pure acetone.  The main ingredient of nail polish remover is ethyl or amyl acetate.

    Nonetheless, I presume that this bikeregister marking is designed to be indelible,  I’d guess that any solvent that removes the dots, will also remove the paint, making your frame look even more stolen:)

    Try acetone aka nail polish

    Try acetone aka nail polish remover but check on an inconspicuous area first it case it damages the laquer.
