Hello,
My favorite cleaning method for grout is baking soda mixed with a little dishwashing detergent and hydrogen peroxide. H2O2 is great for germ killing without the fumes of chlorine bleach and the soda give a slight abrasive. Mix a paste with a few drops of detergent, soda and peroxide. Use a stiff brush to scrub the grout. If the mold is in the caulk, you may need to replace it with a silicone caulk. Drying your shower after each use (squeegee or towel) helps keep the mold at bay. However, sometimes there is an underlying problem with the way the shower was built causing moisture to stay where it shouldn’t.

We always had a problem with mold in our caulk. We did replace it several times with mold resistant and silicone. Still had a problem. When our contractor gutted our shower, he said they tiled over regular wall board and that is where the mold was coming from and why we couldn't get rid of it.

Well we gutted the whole bathroom and redid it. One thing that did work was using toilet bowl cleaner gel with bleach. I would put that around the caulk and let it sit. It brightened it up for a while until the mold came through again.

Yes, a poorly waterproofed shower is probably the biggest cause of mold. Nothing you can do but tear it down. We had one in a spec house that nearly fell through the floor because of the poor waterproofing. Glad we took it out before that happened.

Tilex mold and mildew is quite effective.... And you really want to use bleach to kill the mold.... That tilex product has bleach in it

Concrobium is usually more effective than bleach. Can be found at the big orange store.

For a lot of reasons I won't repeat here...agree with adawn5.

Concorbium.

Unlike bleach, Concorbium will kill all of the mold, including the "roots".

Good luck with your project.

To quote MongoCT's great analogy from another thread:

"Think of trying to kill established weeds in your yard. Using bleach on mold is like using a weed-whacker to get rid of the weeds. You kill the top growth, but the roots remain. The weed will grow back after being whacked, mold will grow back after being bleached.

True mold killers like Concorbium are like using RoundUp on weeds. The RoundUp gets down to the roots and kills the top growth and the roots. Dead.

When you wet a porous material like grout with bleach, the "sanitizing" part of bleach, the 6% sodium hypochlorite, stays on the surface of the grout and kills the top growth of the mold. Due to polarity, it's difficult for the sodium hypochlorite to penetrate deep into the grout. The "other" part of typical bleach, 94% water, penetrates into the grout and wets the grout, and can actually provides the mold roots what they need for growth...moisture.

"Bleach" is not an EPA approved treatment for mold...because it's a superficial treatment only."

So glad I found this thread.

We've had mold problems in all of our showers. Living in Florida, with old bathrooms that don't have proper ventilation for years, the mold issues develop behind the scenes and then it's just a matter of trying to curb the growth, rather than prevent it.

We have had success using a bleach pen, sold in the laundry aisle, to remove the black somewhat and keep the mold at bay. This results in needing to use less bleach and targeting specific areas. But it always comes back.

I'm going to check out the Concrobium. Thanks so much for the suggestion!
