3 year old manufactured home. Water splashes on wall above shower and paint peeled off, mold is growing. Peeled more and this is where I'm at 😫 I read bleach is bad for mold, so I've been putting alcohol on it/not scrubbing. I'd like to remove as much damage as possible, once mold is taken out, I want to put up something waterproof all the way to ceiling. Must prevent mold from coming back. Need advice!
Borax kills mold. You should probably scrape off as much as possible and then spray with the borax solution

You can also use vinegar for mold. There should be moisture-resistant backerboard around a shower and, very often, people tile the area above the shower. Here's a link:

White cleaning vinegar will kill the mold spores even though staining may remain. Make sure you are wearing gloves and a respirator or very good & sealed mask as to not breath it in. I would probably replace with the plastic wallboard that is textured. You see them quite a bit in commercial bathrooms.
If that's sheetrock and it's moldy, rather than scraping, you could cut it out and then replace it with a cement board and tile over it to make sure you never have the issue again.
You can use bleach thinned with water and that should work. Or since you’re looking to protect the part that gets wet you could replace the area with cement board. Or, you can thoroughly clean and repair then cover with FRP, it’s a plastic sheet used most often in restaurants but your local home improvement store will have it.
Bleach cleans mold and vinegar kills mold spores. You can use either but don't mix them together. The fume are harmful. If the wall board is stable you can put bath panels right over the existing wall once it's cleaned. They come in 4'x8' sheets and can be glued right on.

I have used a magic eraser to get mold off of the bathroom ceiling before and it works like a charm!
I would go with vinegar cause vinegar is produced from the fermentation of ethanol and typically contains between 4% and 8% acetic acid. Because of this acid, vinegar, especially when combined with baking soda or hydrogen peroxide, is an effective mold and bacteria killer. While not as strong as bleach, according to some estimates it can destroy over 80% of bacteria. In addition, its production doesn’t take a toll on the environment and breathing in the fumes of vinegar, while unpleasant, is not harmful.
You can definitely use white cleaning vinegar with killing the mold, I will definitely switch it with the plastic wallboard that is textured.
Please use white vinegar for cleaning mold, it kills the spores that cause it's spread along with excess moisture and high humidity.
But rather than dealing with treating the mold, cut the section out and dispose of it. If you choose to cut out and remove the section, consider treating the rest of the ceiling with vinegar for the undetected spores.
Replace the section with moisture resistant cement board.
Or if you do not want to deal with any treatments, cover the whole area with plastic and seal it in.
Vinegar or hydrogen peroxide is a better choice than rubbing alcohol, but I get using in a pinch to use what you have on hand. If it were me? Hire a drywall person to cut out the sections around the tub and use the "green board" to replace, then paint or tile with no worries of mold in the future.
Heat up 1 cup of white vinegar, mix in about 1/4 cup of Dawn Premium. Not the dollar store kind, because it is too thin. When mixed, pour into a spray bottle and fill with water. Shake. Spray down the grout and let it sit overnight. In the morning rinse. If you have stubborn stains, spray again. Once you get the area clean, get some green cement board and replace the rotted drywall. You can either paint or If it is an area that you can tile I would do that to prevent further problems.
Hi Renee, hope this helps you out,

Once you get the mold dealt with you could install a tub surround
That entire area needs to be scraped off. Use a respirator NOT a face mask. You can get one for under $20. You do not want to breath that in. Once removed, paint with a paint specifically made for moist areas like bathrooms or cover with tile. The new 12 x 12 sheets of small tiles that are stuck together on webbing are SUPER easy to install. Just read instructions on box.
You use vinegar to kill mold, or buy some Concrobium spray. Scrape the loose stuff off, then I would skim coat it with some joint compound, prime it and then paint that wall with semi-gloss that will repel water better.
