Dark yellow spots can appear mainly because of mold and mildew or iron from the water. Older water damage and indoor smoking are also significant causes. Consider keeping the windows open to avoid mold because they thrive in humid conditions.

Iron also discolors your ceiling and walls over time. It is best to use a bathroom vent or fan to prevent the ceiling from collecting water. Always have your bathroom installation checked to avoid these spots.

1. Use homemade cleaners

First, use warm water and detergent to wash the affected part of the ceiling. Add a cup of bleach to three cups of warm water and put it in a spray bottle. Sprinkle the mixture on the stains.

Leave the spot for an hour, then wipe with a sponge. Wipe the spot/spots with a wet cloth or rug when finished.

Yellow spots are often caused by water damage. Pipes are affected by hot water over time, leading to holes and cracks. Also, a leaking toilet above your bathroom can be a big problem.

Solving water damage issues is the first step to avoiding future yellow spots on your bathroom ceiling.

3. Clear all the mold and mildew

With a lack of proper ventilation and lighting, bathrooms can be damp and unhealthy. Getting rid of accumulating steam is one way to avoid mold.

4. Paint your bathroom ceiling with quality paint

Even after cleaning, some yellow stains can be hard to remove. You can consider painting your bathroom ceiling to bring back a pleasant look. If you are building a new home, use quality oil paint and let it dry off before using the bathroom.

Always use a primer before applying the paint, and be sure you are painting over dry paint for the paint to stick better.

5. Always protect your bathroom ceiling

If you live in an old house especially, always have appliances to tackle yellow satins on your bathroom ceiling, including protective gloves, a stain remover, a long-handled brush, an old rug or cloth, and a step ladder to reach your ceiling with ease.



If your bathroom ceiling has a water source, check for leaks periodically. Mold thrives in dark places so if your bathroom lacks windows, install a UV lamp. Experts propose using a ceiling fan or opening a window for a few minutes to remove air dampness when you turn off the shower.

If the bathroom is humid, install a small air conditioner and let it absorb the moisture. Mold can quickly form in overheated and steamy areas of your home in winter, like the bathroom. Try as best as you can to leave windows and doors open, and point portable heaters to the ceiling to prevent mold.
