So the walls in my bathroom have streaks all over them. They've been building up over time and is getting worse. The wall over the shower in particular looks pretty bad. Does anyone know how I can get rid of them? I tried spraying Clorox Bleach spray but it doesn't seem to be doing anything. Anyways, I'm open to suggestions.
What that needs is a good scrubbing with warm soapy water. If the paint comes off because it is old or because it is no longer durable enough to survive a good scrubbing... then it needed repainting anyway. Use a high quality gloss or semi-gloss paint if you do it.
The streaks are actually strips of "clean" or at least cleaner than the surroundings.
Unless adjacent to a kitchen, or the room used by smokers the dirt is unlikely to have an oil component. Try the following:
Hot water (as hot as you can stand with kitchen gloves on) and laundry detergent. This is generally good for the mix of dust and water that is the usual problem with walls.
Hot water and TSP if the surface is greasy or smoke stained.
If these don't work
- Warm water and ammonia. Tough on eyes and nose while working with it.
Bleach works the best.
I use bleach all the time. Spray and leave it, do not scrub or wipe off.
