Use ammonia-free glass cleaner.

Yes, it’s safer. Isopropyl alcohol can strip or degrade the nano-coating over time, while ammonia-free glass cleaner is designed to be gentle on surfaces without leaving residue. Streaks are unlikely if you use a microfiber cloth and don’t overspray.

The real enemy here is ammonia, which eats away at those coatings. Alcohol is fine for a quick wipe but repeated use can dull the glide or cause spotting. Ammonia-free glass cleaner (like Sprayway or a simple homemade mix of distilled water + a drop of dish soap) works perfectly. Just spray lightly, wipe with a dry microfiber, and you’re done.

Streaks happen when you use too much liquid or a dirty cloth. The nano-coating actually repels streaks if you keep it clean. So: less is more.
