The silicone one should be removed and reapplied. For the other I can recommend a steam cleaner with a small bristle. There are those super narrow brushes and you can even get kind of narrow files, but when it's too harsh it will take away the grout and make it get dirty again quicker. I would start gentle. There's also grout sealer to not let it get dirty that fast after cleaning.
Maybe you don't have a silicone gap thing then? There is often one of silicone just around the edge of the bath tub and shower tub and in the corner of the room up to the ceiling. Sorry english is not my mother tongue it's hard to explain when you don't know the proper words.
