Bob Flexner says none are safe.
Stay with Zip Strip or similar. Work outdoors to absolutely
minimize exposure. Don't stir the remover film with a
putty knife to "speed the process." That breaks the
paraffin skin, letting the methylene chloride portion
evaporate, exposing you, and slowing down the job.
These strippers are cheap, widely available, effective
on the widest range of finishes, and predictable. Less
effective consumer grade strippers (meaning all of the
others) are a huge waste of money when you buy bottle
after bottle because the last one did little or nothing.
