How to Prevent Yellow Drips

✅ Improve ventilation – Install and use an exhaust fan during and after showers. Leave the door open after bathing.

✅ Wipe down walls – After showering, quickly wipe wet walls with a towel or squeegee.

✅ Use bathroom-specific paint – High-quality bathroom paint resists moisture, mildew, and yellowing.

✅ Clean regularly – Weekly cleaning prevents buildup of oils, soaps, and minerals.

✅ Reduce indoor smoking – Better yet, smoke outside.

✅ Monitor humidity – Keep bathroom humidity below 50% using a dehumidifier if needed.
