A very standard question with very standard search results, just wanted your input as well. My situation is close to the stock picture, but I will focus on removal in the grout areas. I am planning on bleach plus toothbrushes, but I want to be careful not to attack the grout itself too much, just get rid of the stuff on top.
It occurs to me that creating a sort of bleach-based paste might be good. Any solid material I could mix with the bleach? One video suggested something along those lines.
I also find it interesting how the treatments suggest either something very basic (bleach) and alternately suggest very acidic materials (vinegar), possibly for different phases in the treatment. It's like the Andromeda Strain! Curious for what you've found effective.
Why, are your parents coming over?
Anyway, just keep a spray bottle with diluted bleach and a few drops of dishsoap, and every time you leave the shower, give it a quick spray.
Commercial production of citric acid is literally made by black mold because of its acid resistance, so the vinegar people don’t know what the frick they’re talking about.
Vinegar Might be good for removing water deposits and white buildup. Not killing mold.
Bleach kills everything.
Thx, I guess I'll buy the stuff today.
They sell chemicals specifically designed to remove mold. I've also had good luck with steam cleaning.
Yeah, most of them are just bleach.
There is concrobium anti mold spray, but that’s just TSP (trisodium phosphate) at a ridiculous price and it breaks down and actually becomes nutrients (fertilizer) for new mold growth.
You could also try copper sulphate, that will kill everything too, but you’ll get a blue/green hue.
Also zinc chloride, which has no color. Lots of metalic salts are great at killing biological things.
They put zinc chloride in mouthwash now instead of alcohol, so it’s pretty safe. It’s that crystalline stuff that leaks out of alkaline batteries that destroys your device… as planned.
what's X-14? disappears mildew spots, corrodes metal, and smells like toxic fumes. it's great/awful stuff.
Use bleach in a spray bottle to spray the tiles, wait 10mins, use a nail brush for the grout lines and use a sponge for the tiles. Rinse with water. Ventilate well.

Don’t use bleach use borax.
>borax
Interesting...
Heard great things about it but I haven’t tried.
> but I want to be careful not to attack the grout itself too much, just get rid of the stuff on top.
Bleach is the best way I know and safe to your grout unless you do it every month or so. Brushing hard without bleach works but probably causes more damage
> My situation is close to the stock picture, but I will focus on removal in the grout areas
The red/yellow shit in the picture is not mold, it’s fat and soap scum with iron residue which can be easily cleaned with vinegar
>The red/yellow shit in the picture is not mold
there's a kind of red mold as well. it's pretty common. this looks like it actually.
yeah the red is from cyanobacteria
Looks like a whole mess of things, bleach spray first but leave it on for only like a minute, then blast with hot water. Then try something that removes soap and grime, toilet cleaner gel might work but it's aggressive as frick, you'll have to wash it off right away. Will require some manual scrubbing as well. Rinse LOL and repeat
razor blade, hydrogen peroxide and an old tooth brush.
you want to use the blade on tile and get rid of as much gung and deposits of the flat surface. Pour hydrogen peroxide and let it sit for 10 min and the n start scrubbing. Remove broken grout, dry it out very good maybee even use peroxide again, dry it good again then start polishing the tile. Add new grout, maybe add something antifungal to it...
I have romoved mold like that from my shower and its safe, bleach is too harsh imo and peroxide if left on the mold for as long as possible will kill it
anyone have advice about demold for 1k sq ft raised foundation/crawlspace? it's been dehumidified down to under 30%. that took about 4 weeks. is bleach and scrub the go?
I wonder if an ozone machine would be the ticket.
>using a utility knife and razor blades remove silicone
>rub edges with a dry rag aggressively to remove little silicone remnants
>take a razorblade to the lower half tiles
>spray with soap scum removing spray and let it dwell
>scrub faces with a rough side of a sponge
>then bleach the entire shower top to bottom
>let dry
>reapply silicone
Done.
T. Do this for a living

like straight up Clorox or OxiClean or 35% hydrogen peroxide?
how do you deal with old porcelain on cast iron tubs that's getting rough and holds mold? like seventy-year-old (1952 original) tubs that have been foot ground by decades of showering
is here a way to recoat them with handyman level tools?
> porcelain
STop washing your motorcycle in the bathtub.
You might be able to re-polish the surface with cerium oxide. Recoating porcelain is not a homeowner task since it’s glass.
>cerium oxide
Something to research! Much thanks!
Just clorox or normal bleach. Don't mix it with anything or you get poisoned.
No idea how to fix the tub, they are enamel painted and it's hard to do that on your own.
This is the best solution:

I use pool bleach in a wash bottle to remove any kind of mold when I see it. I use the blue toiled cleaner that is a hydrochloric acid gel to remove hard water. I use orange zep pumice soap to remove that dark oily buildup on the bottoms of the shower with a brush on the end of a painters pole. I can make a shower look brand new with about 10 mins of work.
step 1 spray copper sulfate step 2 spray with ammonia step 3 spray with bleach.
This is a good way to make WW1 weapon gasses in your shower
soak a paper towel with pic related and put it over the mold. Leave it for at least 24h, make sure it doesn't dry out.
Sometimes you might need to repeat the process for a couple of days.
It worked for me, got rid of the filthy black mold that was pissing me off because nothing worked.
It worked
Soak paper towels in bleach and just stick them to the wall. When they dry out they fall off and your won’t have mold anymore.
Simple as
