Our state has two stickers on the inside of auto windshields - inspection
sticker & license renewal.
New ones are put on each year. Using a razor blade scraper takes the old
paper off, but sticky residue
is left. Seldom do the new stickers go on exactly where the old ones came
off, so the sticky area tends
to spread.

What would be good to use to remove this sticky residue?

Thanks in advance for your suggestions.
