Sounds strange to me too.
Maybe some of the spray got to bearings for a temp fix, but never heard of a belt making a rattling noise. Especially a noise like in the video.

Edit: looked at the video again. the belts didn't look loose so I can't see the belts being an issue. The rattle sounds more metallic in nature.
Pretty sure a bearing IMHO.
But I guess if the "rattle" went away, I guess it's good... for now.

i would recommend changing the belts if that was the noise. One or both may have a flat spot on it from slipping in the past for example. I don't think it is actually belt "lube" but belt dressing. Its made to soften the rubber belt glazing and has some stick-um compound so the belt will grip better. Its just a temporary fix as it doesn't last very long. Is that what you used to make the rattle go away? I thought is sounded more like your crank pulley bolts were loose etc.

Well good news/bad news....I'm still an idiot!! The PS pulley flew off on my way to a car show. I pulled up to a light-it flew off-light turned red-I picked it up and the belt and continued to the show.
Driving manual steering w a torn rotator cuff was fun...said no one EVER
