Abstract
A stain removing composition having a mixture of N-methyl pyrrolidinone and at least one solvent from the group consisting of 3-pentanol, dipropylene glycol monomethyl ether, propylene glycol n-propyl ether, and diethylene glycol monobutyl ether. Preferably the stain removing composition comprises, in percent by weight about 70-90%, N-methyl pyrrolidinone and about 10-30%, in percent by weight, at least one of the solvents from the group described above. In another embodiment, a method of removing a stain from a textile includes the steps of applying the stain removing composition to an area of application. After the composition has been applied to the area of application it is removed with a suction device or other type of absorption device.
