I'm looking for a product that will bleach mold that has grown past the surface into grout. Surface cleaning with a brush won't remove it. Something with these ingredients will do it but if you have a better suggestion I'm all ears. If there is no English brand name perhaps you can snap the label and upload the picture. Thanks

Sodium Hypochlorite

Sodium Hydroxide

Homepro

Sodium hypochlorite when dissolved in water is Bleach aka chlorine.

Sodium Hydroxide is common lye.

Try this product. I buy it at Tops. Not cheap but works GREAT especially when the shower starts to get moldy. Contains Sodium Hydrochloride. This contains bleach and is slightly thick and adheres to surfaces well. I typically let it sit on the surface for a spell before scrubbing with one of those plastic abrasive pads like the blue scotch-brite pads.

yeah, that sounds good.

Common laundry bleach has sodium hypochlorite as its active ingredient

Lye is sodium hydroxide.

Here's what I use to bleach the mold stains- common laundry bleach.

If it's a bad stain, I put a few dry tissues on the stain, soak the tissues with bleach, then let it work for an hour or so. When I take up the tissues, the stain is usually gone.

Flush the tissues down the toilet, and it gets a cleaning, too.

Are you certain it is mold? Common problem I run into is, it isn't mold, but a grease or oil. Neither of which will be cleaned by bleach.

Mr. Muscle Bathroom Cleaner. Orange spray bottle that shows a shower nozzle (not a toilet). I use this in the kitchen to bleach wine stains from glasses, etc.

Promax Toilet Bowl Cleaner. Royal blue squeeze bottle with red top. Real thick product with 3% sodium hypochlorite. This is great stuff for cleaning grout because it's thick and stays in place.

Really all you have to do is take along a magnifying glass to read the small print on the back of the bottles. All the ingredients are listed in English.

I use "Vanish Power O2", purchased at TOPS.

It's a good general purpose bleach, great for sterilising a batch of bottles for home brew, (if you're in Oz) baby's nappies or whatever. Also good for moving stains from clothing.

I make up a thick paste of this and apply it with an old toothbrush to stained grout and leave overnight. As it's alkaline, it does not damage the grout.

Toilet cleaner is acid and will erode away grout.

JIF which i know is sold at Villa Super Market is a great scrubbing cream that is great for percelen and bathroom tiles

7 cups water,
1/2 cup baking soda,
1/3 cup lemon juice and
1/4 cup vinegar
throw in a spray bottle and spray your floor or wall, let it sit for a minute or two... then scrub.

+1...that's what I use, works great. Sold at Big-C and many other places.

OK, Ill tell you what NOT to do as i did.

I started mixing toilet cleaner with Mr Muscle Bathroom cleaner. Cleaned the grout back to a brilliant white in no time.

But the fumes were horrendous, then the grout dissolved and all the stainless steel fittings went black, never to return to silver colour, and the white paint on the door went dirty brown.....god knows what i did to my lungs....anyway

DONT DO THIS !!!

PS Baking soda, lemon juice vinegar and rub hard ? waste of time, doesnt get stains out and is just 'natural health forum' nonsense........

You really need to remove the moldy grout by scraping it or digging it out . put in new grout only way of really getting rid of it for sure.

You can not kill black mold !!!!! This is why they have to tare the walls out of moldy houses. You have to remove what it is growing on, very nasty stuff. can slowly poison someone living in a home with it in the walls. Google Black Mold .

Get an spray bottle and fill with raw bleach and add lemon juice and spray the walls and leave it for quite a few hours.

It will work

True

If it has already gone so far as to penetrate into the Grout, or worse the tile, the only thing to do is to remove that, and put new Grout or tile in.

7 cups water,

1/2 cup baking soda,

1/3 cup lemon juice and

1/4 cup vinegar

throw in a spray bottle and spray your floor or wall, let it sit for a minute or two... then scrub.

If you do this, make sure you record the video so we can all have a good laugh.

Lye packets are available at my Big C as 65% sodium hydroxide, in the area with drain openers.

You had what we used to call a "chlorine release" back when I worked in a chemical plant. At least you didn't have to write up a bunch of safety reports afterwards.

As for your lungs -- when you breathe chlorine gas, it combines with hydrogen from the water in your lungs to form hydrochloric acid. Can do some real damage to your lungs at certain concentrations.

They sell some household cleaning preparations here that wouldn't be allowed in the U.S. I used to bring 'em back with me from Thailand back when we traveled between the two countries. Always good for conversations starters at the safety meetings at the chemical plant when we had programs on "household safety".

I used this Soft Scrub in the states on my sneekers before putting them in the clothes washer, made them look like new! Good to know they have it a Topps.

Youre right, the stench was chlorine.....I didnt have to write up health and safety reports but i did have to explain to the wife why the third floor was out of bounds for the night and why i needed to spend a fortune at Homepro on new bathroom fittings lol ;-)

Inadvisable. Certain kinds of acids can liberate the chlorine in the bleach and produce toxic chlorine gas.

Homepro -- there is a product in the "HG" line of household cleaners. Its pricy but it cleans the grout with almost no effort. Squirt it on. Wait a bit and spray it off with water.

hydrochloric acid is one,nearly gassed myself when adding chlorine to a pool,used a bucket that had been previously used for said acid

+1. We used to use baking soda and vinegar to make an exploding plastic bottle. As small kids, that's what we used to power our volcanoes at show and tell. Mix 'em together and watch the foam run out all over the place.

I just use a spray bottle filled with common bleach (1/3) and water (2/3) and just spray it on. Doesn't seem to harm the grout and does clean up bathroom mold (and I've never had to scrub). I also use it every month or two on the bottom edge of the shower curtain that used to get a bit moldy over time. Mild side effects: (1) it will over time slightly lighten the color of the shower curtain (but I don't care), (2) a bleach smell for a while (which doesn't bother me....sorta smells like bleached whites coming out of a washer), and (3) the bleach over time (a few months) will eat up the plastic mechanism of the spray bottle and then you need to replace the spray bottle. But works like a charm.

I just use Hater bleach for everything BUT DUCK should do the job..either the white or purple bottle has the highest concentration of sodium hydrachloride (15%)

I read this trick many years ago in a home improvement magazine.....it's always worked when nothing else seems to do the job.

Make a thick paste of baking soda, and about a 50/50 mix of bleach and water. You want the paste to be thick enough to not run when applied.

Apply the paste to the affected area with a small paint brush. Let stand for several hours. Rinse off thoroughly.
