Melbourne

I've bought the moisture absorber tubs from the cheap shop and when they're done I refill from a bulk bag of damprid. My bedroom window is the worst, shaded by trees and shrubs and this has stopped the mould from growing.

Shrinking underpants at my age and stage in life I do not need🫄🏻

Edit: Have aluminium framed windows that are infested with mould from the previous people who lived here. It's been a battle to keep it under control. So far I've used Ajax Professional (stinks but good product), White King Mould and Soap Scum Remover (Stinks slightly less but good product) and they've been the best. But Elder minipeeler hates the smell of bleach and chlorine, gives him headaches. Hates swimming pools for the same reason, any amount sets him off. So recently when I went to the farmers market I found a product which has clove oil and eucalyptus and doesn't upset elder. It wasn't cheap but I'm desperate enough to try it, and it works ok in my bathroom so I'm going to try the window frames on the weekend. I'll let you know how it goes.

According to my Spotless book it says

MOULD REMOVER FOR HARD SURFACES: Mix 1/4 of a teaspoon of oil of cloves in a 1 litre spray pack of water. Spray and leave for 24 hours before respraying. Wipe with a clean cloth.

As for absorbing moisture I'd buy a large tub of chalk, tie them together and hang them on the inside of my blinds/curtains. I do this in my bathroom basin cupboard because it gets damp in there.

Every morning I wipe down the windows with paper toweling to mop up the condensation.

For the windows covered by fly screen, I open them slightly and close off the room until the water has evaporated from that window.

So far, this has kept any mould issues at bay by being diligent and clearing the moisture away before mould can take hold.

I get it in a couple of rooms. Indoor humidity will come from showers, cooking, breathing. Because window glass is cold the moisture can condense there. I put one of those moisture absorbent containers in the affected windows. Open the blinds every morning to ensure air circulation at the glass. This combined effort fixes the problem. Baking soda is not a good moister absorber, so won’t work like the proper absorbents.

I'm a little bit surprised, but we don't really have humidity problems here. Even during los tiempos difíciles, when I spent 20 or so hours in my room with no windows open and the door closed for 99% of the day. I wonder if it all escapes through the same way as the heat.

My bathroom suffers from mould issues sometimes, but it's just about entirely my fault. The fan and light are on the same circuit, and there's also a skylight. So if there's enough light from the skylight, I often don't turn it on. It also sucks out all the heat and warmth, and ain't no-one want to get out of a shower into a 12° room
