[Update] Help! Mold on the rubbery part of the window T T

It’s been almost two weeks since my I asked for help here https://www.reddit.com/r/germany/s/fEtdQeT4UB, so I would like to give an update on the mould situation!

Thanks to the suggestions there, things have improved drastically, so I would like to share this in case people need help with this too! I ordered this mould remover from Amazon Professional mould remover against mould, mildew, mould stains and Mould I chlorine-containing anti-mould spray. https://www.amazon.de/dp/B07FZMXT44?psc=1&ref_=cm_sw_r_apin_ct_WGXE3SWMWM5GM02QNCF4&language=en_US, and applied it on kitchen towel so that I could lined the it on the affected area. The first pic is before any use, while the second is after my first time using the method for 2 hrs. Since I saw no damage on the window frame, I went on to use the method for 8 hours, unfortunately the paper towel dried up but the colour is much lighter already (pic 3). I tried again for 8 hours but this time with a lot of the detergent to make sure it stayed wet (pic 4).

It’s not completely, completely gone, but it’s barely there. I need to stare at it propery to see it. So this is a big success!

Thanks to the kind people on Reddit!
