This summer, I started noticing a cloudy film on my shower screen that wouldn’t wipe away easily. At first, I thought it was just regular soap scum, but after a few days, small patches of mould appeared along the edges. The bathroom felt more humid than usual and even with the exhaust fan running, the moisture seemed to linger. I also saw tiny spots of rust forming on the metal frame. It made me wonder if the summer humidity was causing this. I never had these issues in winter so I decided to look into whether the humidity was to blame.
