How To Make Bathroom Drain Smell Good. The best way to get rid of the musty smell is to pour baking soda into the drain, followed by white vinegar and then boiling water. Try to avoid putting ‘bits’ down your drains (both in bathrooms and kitchens) and clean the drains regularly.
The baking soda and boiling water will do a good cleaning. The constant damp conditions in the shower drain, coupled with the dirt that serves as nutrients, provide the best conditions for mold and mildew to grow within the drain. After that run the cold water for a minute.
(watch out, it’ll fizz.) wait.
When it starts to fizz, you can pour it down the drain, then follow it with hot water and let it sit for at least an hour. Use this solution to clean bathroom tiles, shower curtain, spray some in the toilet bowl, use to clean the toilet bowl, spray some in the face basin drain, on the counters and so on. No one likes the overpowering scent of febreeze. If you spray the entire bathroom in a mist of febreeze you might just cover the smell, but make it worse in the process.
