Pour-N-Restore can adversely affect some sealers leaving a white residue, shiny residue, or powder embedded in the sealer. The solution is to strip the sealer with more Pour-N-Restore. Apply it to the affected area; let it soak for 10-15 minutes, and scrub. After 30 minutes, scrub again, and then sponge Pour-N-Restore from the surface, or rinse, to remove the sealer. When the surface is completely dry, you can apply Pour-N-Restore to the embedded oil stain following the directions on the bottle.
