The pink stuff in the spray bottle? I've washed my bike quite a few times since owning it using other cleaner, and tried that stuff a few months ago - it is vicious! Whatever the dealer put on must have stayed on all that time, because the MucOff removed it, and the 5 year old plastics now look like, well, like 5 year old plastics that have been in the sun (plus adhesive marks/bleached sections because of stickers). Nothing that a bit of bumper back to black didn't hide again :P
I'm with Fat Rat though, they hopefully will be able to colour match it!
