Unfortunately I had determined for 2 years ignored the growing mold, which is otherwise relatively easy removed with acetic acid. From light to dark gray everything was represented, and not just superficially, but in places already 1-2mm in height.
Also in the frame itself to many galactic black adversity amounts had accumulated, as showed me the complete opening. Before this I dreaded most, they saw but almost after "here only helps to scrape, abrade or burn" out.
Rubbing with Essigsaeurekonzentrat -> as expected none.
Soaking with 'DanChlorix' -> very slight improvements.
Brushing with the 'Chlorox BleachPen' (this in there I do not think .DE) gel contained -> bit better.
But nevertheless decent amounts are above all in the corners of the silicone seals very resistant retarded, not to speak of dark spots. The gray mass was easy.
According to research in nae. local hardware store (here there was just only 'Schimmel-Ex' (PT10) to use primarily for masonry, which I not getting myself) I went with the resulting statement, "If it even disappears with Chlorix not immediately, only helps rip out and · redo" back home I had the reviews here but already read; did I really want to bring the experiment with mold destroyer behind me - new grout 2 double window (leave) makes no joy..
So on to nae., Somewhat further away Baumarkt another, already mentioned in reviews as a product supplier, chain. This was luckily really all Mellerud range. That I had to pay attention to "-Vernichter" and not to "remover" I knew.
As it is written: Spray from about 5cm ~ 1h soak, wash.
And then the assessment ...
I had seriously before and after pictures to make the documentation; because: the one believes no one else who has already tried it net itself.
Although there are still spot as slight discoloration exists, but this is after all this time undisturbed growth no wonder. Already without rubbing or wiping are min. 90% of persistent, thick Restbestaende be disbanded.
I will simply repeat the treatment for 1, 2x; the remainder of the silicone is also look great again.
Also div. Grayish discoloration of the joints of my s bath were excellent & fast away.
Thank Mellerud!
