Using Protective Overlay or Anti-Graffiti over-Laminate for your Signs

10th Jun 2020

If you are using protective overlay film for your signs there are a couple of simple things to keep in mind when cleaning off grease, spray paint, permanent marker, etc.

Many stains can be removed using a simple dishwater detergent. For harder to get off graffiti, there are several products designed specifically for spray paint removal that work exceptionally well.

Getting rid of normal dirt accumulations on your signs, the use of a soft cloth with microfibers and water solution followed by a thorough rinse can do the job.

It is best to carefully read and follow product use and safety precautions prior to using. Test a small area with the cleaning solution you are using on your sign to determine its suitability and be sure it doesn’t cause any unwanted stains or marks on the laminate.

Avoid using strong polar solvents such as; ketones, (acetone, methyl ethyl ketone) or methylene chloride (dichloro methane) and other chlorinated solvents.

Industrial cleaners with citrus base can be effective on some of the common types of sign defacement from permanent markers, pens, eggs, and stickers. Solvents such as isopropyl alcohol and/or a 50/50 blend of isopropyl alcohol and xylene can be effective in removing paints and lacquers.

For removing adhesive off of sign blanks we recommend using NAPA – Kleanz Easy.

When using isopropyl alcohol or other household cleaners, spray the stain and let it sit for approximately 1-2 minutes. Use a soft, clean and dry cloth to buff out he stain using pressure and a steady smooth circular motion. 

You may have to repeat several times for stubborn stains. 

Be sure to read all manufacturers' Safety Data Sheets (SDS) for important health, safety and environmental information.
