What's wrong with this hose?

I replaced several hoses this spring and I just noticed this one looks real funky. It is covered along its entire length with this white chalky material. Is it failing?

Salt from snow clearing?

Ive noticed a lot of rubber parts get this coating. . Not sure what it is, maybe some residue from manufacturing that oxidizes or something..?

Rub it with some WD40, it will come out nice and you be able to see any crack or flaw.

I don't know about the salt- we don't really use that around here but the other hoses don't have this at all anyway. And I replaced several houses at once and they came in the same order and this is the only one that looks strange. May try the wd40 just for the heck of it but it is odd how the film is evenly spread over the entire hose.

Ditch it in that case just to be safe

I replaced a coolant hose that had a leak on my explorer and the brand new one looked the exact same as yours does; it never gave me any problems though. Every now and again I would put some tire shine or similar on it and it'd look good for a few weeks then that film would return.

Most manufacturers us a mold release and a rubber preservative on them. You see it in many rubber trim pieces too. You can leave it or clean it with Armor All.

Just leave it. Not an issue at all. I have had a bunch like that. Key thing with hoses is to give them a squeeze whenever you service the vehicle and see if they are soft or the outside is starting to decay.

What others said, nothing to worry about, just a film from the manufacturing process, I've seen lots of hoses with it. Your new hoses are different sizes and shapes, thus they are coming from different batches and potentially different specific materials, that is why they don't necessarily all look the same and have the same film. Clean it off and don't worry about it. Like Ron said, just keep an eye on all of them, especially as they age again.
