I use alcohol on a daily basis in my store; I suggest not skimping by purchasing either 50 or 70%. The few pennies saved are not worth the extra effort, as 91% is so much easier labor and time wise.
I agree about the higher percentage alcohol.
For whatever reason, the privately owned stations seem to be more trouble.
I think that when the stickers were first added, the method was to use a separate, better glue than the sticker's glue to apply the white dot. Then they would apply the sticker to the white dot, ensuring a good application. That method seems to make the glue under the white sticker thicker and harder to remove.
After doing some of these, I figured out that the best time to do these is in the middle of the day. The pumps are warmer and that makes the sticker warm and supple. The sticker is then easier to remove and the glue is more pliable.
Ensure you use a plastic putty knife/scraper, not metal of razor. Scratches cane result!
Use alcohol.
First, use your plastic putty knife to remove the sticker and the white dot beneath it.
Next, use the putty knife to scape as much as the white sticker glue away.
Last, I use an old wash soaked with a bit of alcohol wrapped onto the putty knife to rub off the excess glue.
That seemed to work for me and I got my timing down considerably
