Something on paintwork after having brakes fitted

[Stoneilove]

Hiya, I got my bike back from a shop after having my brakes fitted, noticed today an area that looks dull and matt, tried wiping it of with alcohol spray but still not improved, it smudges and smells weird, any idea what might of caused this and how to repair?

It could be an oily handprint, but it is probably some brake fluid spilled and not wiped off fast enough.

Try car polish.

what bike is it? my Trek rail is only 3 months old and the paintwork has little dull spots in places. its really annoying to be fair.
i was thinking of getting some ride wrap, i've read that can make it look like new again?

Turbo levo, the paint work was immaculate before taking it into the bike shop.

Yeah, they said to use some alcohol wipes, tried that and it did nothing, emailed a photo to them and waiting to see what they say..

It looks like fine scratches ,the sort you might get from a bike stand clamp,but they look to be above where the shock is,so it can't be that.

I'd try some car polish on it, that might shift it.

I would heat it a few times with a hairdryer. Not to hot. Just warm it up. You want to drive out any residual fluid that may have migrated into the paint. Then rub it out with some toothpaste on a paper towel when the frame is cold. Seriously. It makes a great mild rubbing compound that will polish up the gloss. Then hit it with some car wax to protect. If you want further insights, PM me. I was a paint chemist back in the day......

Many thanks, i was able to remove it using some disk cleaner, took 3 attempts but managed to remove most of it.

Something to be said about if you own an ebike then we need learn how to do repairs ourselves. Brakes and even bleeding the lines is pretty easy. I see shops using bike stand clamps on the paint work. Lotsa how to Youtubes up there. Everytime I bring my cars into the dealerships they leave with scratches or rattles where they did not screw (or just left them out) or properly torque everything back in place. Several times over the years I've found their tools left under the hood. Many independant auto shops don't even know what a torque wrench is less use one.

If the bike has SRAM or similar brakes, it could well be DOT brake fluid. It’s caustic and will eat paint, distort plastic, etc if not properly cleaned or removed after service. It only takes a few minutes to do damage. After servicing, you can kill it with a damp cloth (water); simply wipe it off. Once I do that, I do the remaining cleanup with alcohol. Of course, don’t get those chemicals near the actual brake fluid you intend to use for the service. I had a beautiful anodized burgundy 2010 Stumpy Expert that was ruined with brake fluid that sat on the finish while being serviced. Learned how to service brakes after that!!
