NiSi 奈米光學清潔組

I was skeptical about spending more on a cleaning kit, but the protective coating this leaves on my filters is a game-changer—dust just wipes off way easier now. It really is residue-free, which I’ve struggled with other sprays.

Finally, a cleaning kit that doesn't leave streaks on my ultra-thin nano coated lenses. The residue-free formula really works, and I love how it leaves a protective coating instead of just smearing dust around.

I was a bit skeptical about the residue-free claim, but after using it on a few lens filters, I’m genuinely impressed by the protective coating it leaves behind. The spray nozzle gives a nice fine mist, so I don’t waste a drop of the solution.
