• Light Contamination — Membrane that has been exposed overnight up to a few days to air-borne debris, foot traffic, or dew or light precipitation can usually be cleaned with a white cloth moistened with EverGuard^® TPO Cleaner.
• Be sure to wait for solvent to flash off prior to welding.
• Dirt-Based Contamination — Membrane that is dirt encrusted will require the use of a low-residue cleaner, such as Formula 409^®, and a mildly abrasive scrubbing pad to remove the dirt. This must be followed by cleaning with a white cloth moistened with EverGuard^® TPO.
• Exposure-Based Contamination — Membrane that is weathered or oxidized will require the use of EverGuard^® TPO Cleaner and a mildly abrasive scrubbing pad to remove the weathered/oxidized top surface layer. This must be followed by cleaning with a white cloth moistened with EverGuard^® TPO Cleaner.
• Unexposed membrane left in inventory for a year or more may need to be cleaned as instructed above.
