TYTAN Foam Cleaner may be used to remove any unwanted uncured polyurethane foam. It may be attached to most gun dispensers. The attached spray nozzle may be used to remove external uncured foam from dispensing guns to extend the life of the tool. The cleaner may be used on most construction materials or even fabric but it may cause discoloring or leave a residue. It is not harmful to skin in small quantities but it should only be seen as a last resort if gloves are not used.
