Do you know how a bathroom gets all steamy following a hot shower? That water does not simply evaporate. It goes into the walls, ceiling,and also the paint. If you leave it that way for too long, you will get mold. Molds are tiny black patches that smell terrible and cause sickness. They are very serious problems because they cause sickness in homeowners.
The solution to water going into walls us by drying the bathroom so the walls can become dry. The bathroom fan is important at this point. Every time you take a shower, run it and then leave it on for at least twenty minutes after you already left the bathroom. But a better fan if the one you have is not working properly or buy a new one of you don’t have at all.
Also, you can open the bathroom window. And Let the wind do its work. You can also use an old towel to wipe down your shower walls as well. All these won’t take you more than 10 seconds and will save you a lot of time later. If you do these small things every time, your bathroom will remain dry and spotless. No mold, no damage and no need for cost future repairs.
Good practical advice overall especially running the fan after the shower, that’s the step most people skip. Even just wiping down surfaces and getting airflow going makes a big difference over time.
