Make sure your glass surface is clean.
If there are stains or mineral build-up, we strongly advise restoring your glass so it looks as good as new.
Use our Glassguard Restoration Stain Remover or our Glassguard Magic Glass Restoration Nano Sponge for heavy soiling.
Once the glass is restored as best as possible, clean the glass using the Pre-Cleaner solution (alternatively use an alcohol-based cleaner).
Dry the glass, and ensure it is free from any residue that might interfere with the Nanocoat treatment.
