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.

Razor blade scrapers work perfectly for that purpose if used correctly, at
about a 30 degree angle from the glass. If the glass is round, scrape in the
round direction. And always use a brand new blade.
I've never had a problem that way.
