Hi Amanda,
Thank you for your question about ChartPak Vinyl Letters & Numbers.
This set is ideal for lettering glass. Just stay away from any solvents or alcohol based cleaners. That will damage the vinyl and eat away at the adhesive. Your average vinegar- or ammonia-based window cleaners are just fine.
Hope this answers your question!
Best,
Frankye
