How do I get mold off a stippled ceiling over my bath tub?

Janice that’s a tough one. Have you tried to spray bleach on it? You’d have to be very careful to not get it on you.

More even use a sponge and gloves to apply. The ceiling being lumpy will

be the issue. A soft brush may help very lightly.

I hope this helps get your ceiling clean again.

Mans yes the fan will improve things.

There are mode collection kits at the big box stores that you can purchase to see the level of contamination you have. I would do that before I went any further.

If it is just a minor problem and not the dangerous kind, investigate how to remove this. Then seal the ceiling with Kilz and repaint the ceiling. If you do not seal it before painting, any stains will bleed through the paint.

Any of the big box stores should have a mold removal product. Again, here is a link from Home Depot (I do not work for them, but there is one close to us and we use them all the time!)

I have never used these products, so I am not endorsing them. I found these on a search: https://www.walmart.com/ip/Zinsser-Mold-Killing-Primer-Quart/43380441?wmlspartner=wlpa&selectedSellerId=0&adid=22222222227033196562&wl0=&wl1=g&wl2=c&wl3=81767220249&wl4=pla-138670931289&wl5=9016857&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=online&wl12=43380441&wl13=&veh=sem&gclid=EAIaIQobChMI1Iuvq9Kp3wIV2LbACh1cXAY-EAQYASABEgKUg_D_BwE , ttps://www.homedepot.com/p/Concrobium-14-1-oz-Mold-Control-Aerosol-027-400/205180046

Here is a link to some stuff I have used outside. I found out they have an indoor version, which I have not used. But the outdoor version I have used, is amazing. It is also safe on most anything. It takes about one week for the mold to disappear, but it does eliminate it. I got it on Amazon. Here is the link: https://www.qvc.com/Wet--Forget-Mold-Mildew-Moss--Algae-Sta

Here is a better link, the other one doesn't work all the time: https://www.amazon.com/b?node=18474278011&pf_rd_p=232b26c4-0518-4896-8818-23b3a928818f&pf_rd_s=detail-ilm&pf_rd_t=201&pf_rd_i=B00GVCXTHC&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1CQ688SP32ACE83Y7EMR&pf_rd_r=1CQ688SP32ACE83Y7EMR&pf_rd_p=232b26c4-0518-4896-8818-23b3a928818f

Plain old vinegar will do the trick.
