Hi I would try a fungicidal wash. It sounds like has started to form penicillin.

Hope this helps, If you need anyone to do this for you please let me know.

We had this in ours but found out that next door had been relevelling their floor by use of acid products which caused this to ours. Probably not an acidic reason. Do you get damp or water in there maybe as puddles. Could be limescale.
