Few months ago I bought a Dyson Airwrap multi-styler in color blue/blush and after 1-2 month of inconsistent and gentle using, I notice strange prints or stains, can't identify it. I thought it was dirt and tried to wipe it off, but it didn't work out. So now I think it's a coloring problem. Can you please explain me what's wrong with my styler and how can I fix that issue.
