Step 5 · Final Cleaning with a Solvent
After all solid putty is gone, an oily residue will remain. To remove this, pour a small amount of a mild solvent, such as isopropyl alcohol or mineral spirits, onto a clean rag. Vigorously rub the entire area where the putty was located. The solvent will dissolve the oily film. You may need to apply more solvent and switch to a clean section of the rag to fully remove the residue. Once clean, use a final, dry rag to wipe the surface completely dry. The area should now be pristine and ready for the application of new plumber's putty or sealant.
