Does it contain ethanol, and will I smell it?

Yes. Ethanol is the solvent in Koh Bathroom & Shower Cleaner. It cuts oils and helps the foam spread evenly across tiles and glass. There's no added fragrance, so the light clean smell you notice while spraying is the ethanol, and it fades as the surface dries.

How long a box lasts

About 6 months

One box, weekly cleans, average home. Heavier use runs shorter.

⚠ Two storage notes worth knowing

Don't freeze it and don't leave it in a hot car or on a sunny windowsill. Heat and freezing both work against the thickener and the enzyme, and a box that has been through either can look or pour differently. Store it sealed at room temperature and it behaves the same on the last spray as the first.
