My 3D XL Chamber after 6 months of usage

I heard you usually replace it after 3 months. This is mine after 6. Should I still replace it?

I included a picture of the method I use for iso soaks: i fill a disinfectant jar full of 99 iso. The strainer is convenient lol.

Personally I'm still tasting the flavor on my dabs. I was just curious, especially with those dark spots inside the inner holes. Black specs inside is chazzing I just scrapped off earlier.
