Patent ID: 8728245

Claim:
A method of removing adhesive residue from a substrate comprising the steps of providing an adhesive remover composition comprising one or more non-halogenated organic solvents being a primary solvent component, a non-abrasive thickening agent, a surfactant, a vapor-pressure modulating agent, and an absorbable indicator dye, wherein the total Hansen Solubility Parameter at 25° C. for each of the non-halogenated organic solvents is from about 14 MPa 1/2 to about 24 MPa 1/2 ; applying said adhesive remover composition to a substrate that has an adhesive residue adhering thereto; permitting a sufficient amount of time to lapse during which the adhesive residue becomes incorporated into the adhesive remover composition, but not so long that the adhesive remover composition becomes substantially dry; removing the adhesive remover composition to produce a cleaned substrate; and inspecting the cleaned substrate for the presence removal of adhesive residue; wherein the step of permitting a sufficient amount of time to lapse during which the adhesive residue becomes incorporated into the adhesive remover composition further includes permitting a sufficient amount of time to lapse for the absorbable indicator dye to absorb into or onto the adhesive residue.
