Hello, since a week or two black mold has started appearing in the bathroom, I tried removing it with some products (I didn’t try bleach or more serious stuff yet) but it came back shortly after. After that, I noticed that there is mold also behind the bathroom radiator. I am pretty sure it was already there when I arrived approx. 2 months ago, but I just thought it was dirt and since it is so hard to clean behind the radiator I didn’t care.

I do Stoßlüften two times a day in my bedroom and in the bathroom. I always open windows when taking a shower.

I was wondering what is the best thing to do. Should I contact my landlord and send her the pictures? My roammate told me that they didn’t have mold problems last year, so I am scared the landlord will think it’s my fault.

  1. You should definitely inform your landlord. If not, you could be liable for any damages that come from this (§ 536c Sec. 2 BGB). It looks like typical mold as the result of high humidity, but the landlord should at least check if this is the case. It doesn’t look to be bad, so it should be relatively easy to get rid of.

  2. Inform your landlord yes.

    Don’t use bleach on it – try vinegar in a spray bottle first and if that doesn’t kill it, buy proper anti-mould spray like Schimmel-X
