I also find those three, three language visor labels annoying. So I got around to removing them today.
On pasted vehicles I would remove the visor. Use a water soaked lightly rung out linen towel and iron on medium. Place the towel over the label and heat with the iron. What happens is the heated wet towel will steam off the label and absorb the glue as the label releases. A second apply of a clean wet area of the towel on remaining glue would finish the job. Not so with the MKC.
Once the two
#20 torx screws were removed on the MKC, I could not figure out how the visors wiring would come apart, as only two inches max of the wiring came out of the head liner. Well,
Plan B, with the visor off the head liner and hanging by its wire with visor extended I held it with one hand as I heated a label with hair dryer for like a minute, got hold of a corner with finger nail. Next, used small pliers to grab the corner and more heat to lightly peel off the label. The visor material stretches but will return as it cools. Next, I sprayed
Goo Gone and lightly rubbed it into glue area with one finger. Let it set for a few minutes, then I warmed the linen towel with the hair dryer and rubbed the area for like a minute. Repeated this two or three more times on the large labels. The small label for some reason, required five or six times. I washed out the towel in warm water and re wiped the area twice, done. The material took the abuse and came out fine, I'm pleased.
Note, I also used a large bath towel to protect everything else.
