Window & glass spray

This spray is designed to dissolve mineral deposits and soap residue — the stuff that leaves streaks on your windows and glass, and cloudiness on shower screens. It's citric acid doing the work here (works like vinegar), just without the smell.

Tips for best use

If the glass has visible grime, fingerprints, residue, or a greasy film, an acidic spray on its own won't give good results. That layer needs to be removed first.

Clean the surface with a multi-purpose spray or paste first. Once the glass is clean, follow with this acidic window and glass spray as a finishing step. This two-step approach prevents streaking and stops residue from being spread around the surface.

Good to know

Can I use vinegar instead?

Yes — diluted or undiluted vinegar works as an alternative to a citric acid solution.
