It is very important that you use an acetone or nail polish remover suitable for hands. Read on the product’s labeling the convenience of its application on the hands and, if in doubt, buy the usual acetone to remove nail polish and not another that is used for other surfaces.
Apply 91% isopropyl alcohol
In addition to acetone, you can use rubbing alcohol to remove foam sealant from your hands . It needs to be 91% alcohol to be most effective and will of course be more helpful if the foam hasn’t fully dried yet.
- Wet stains : Wet your hands with the alcohol, rub them in for a few minutes, as if you were washing them with soap and water, and dry your hands with a clean cloth.
- Dry stains: If you have not been able to prevent the polyurethane foam stains from drying, fill a deep plate with 91% alcohol and insert your hands for a maximum of 10 minutes.
