Any tips to prevent potential musty smell from drying clothes in shower room?

I just moved to Tokyo last week and I’m still apartment hunting but I’m living with my grandma for now. She dries her clothes with a drying rack which isn’t my exact jazz especially with the weather these days but I know that a lot of ppl use the dryer in the shower which seems pretty effective! I’ve been seeing some tips online like buying certain detergents to prevent any mildew-y smell when the clothes dry but I wonder if anyone here has any other tips? I’ve literally only used a dryer machine my entire life so I also considered buying those 2in1 washer/dryer combo machines but it seems like the reviews are really bad lol

Any tips help!!! My gramma is the only Japanese person that I know and she’s super old school so I’m just starting from brand new pretty much so even if it sounds like common sense, please tell meee!!
