WD-40 for Removing Adhesive

I had put the little self-adhesive plastic strips in my bathtub several years ago. They worked quite well, and they stayed useful for several years. They eventually began to peel around the edges and I decided to pull them off and go back to the rubber bath mat.

I could not get the adhesive off! I tried bleach, Comet, and lots of different types of "miracle" cleaners. I used these with Scotch-Brite scouring pads and I even carefully used steel wool. The adhesive marks would pretty much disappear, but a week later they were back! I had given up on getting rid of them, but I had started keeping a can of WD-40 under the sink for assorted uses. I thought I'd give it a try. I had read of many wonderful uses for it before. I sprayed it on, used a new Scotch-Brite green pad and plenty of elbow grease [LOL] and rinsed well. Finally! The marks are gone now for good!
