Krud KutterMold & Mildew Stain Remover Plus Blocker - 32 oz

Initially very disappointed because took lot of scrubbing to remove mildew & ended up using an inexpensive portable toothbrush to get all the grouting done (LOT of small bath tiles). However, per mfr directions, I began regularly using it as a maintenance product. Upped frequency to weekly for awhile, and began noticing not only less mildew return, but what does appear is easily wiped away with a cloth -- like magic!So, well-worth the amount of initial effort, especially where other products have such strong odors feel like am asphixiating! Additionally, this tub is very old, so was worried about potential damage, since I'm a renter & other cleaners can be harsh, if not toxic.Only problem? I used up that first bottle fairly quickly, and was unable to locate it where had previously purchased it so ordered through Amazon. While my other 3 bottles of Krud Kutter for kitchen & general use arrived intact without issue, wouldn't you know the one I needed the most was leaking, and had to be pitched?! (Amazon issued a credit with alacrity, but that sure doesn't do anything for my mildew-prone grouting!) So now I'm kind of scratching my head debating about whether to try my luck again and see if Amazon can deliver something that doesn't leak or try to source & locally.P.s. I had such fantastic results with the original Krud Kutter product I have switched out almost all of my cleaning products now for a Krud Kutter brand alternative, with the added benefit that accidental skin contact has negligible impact --- though ALWAYS wash off with soap & water ---- NO WAY suggesting anyone use this as a cologne or moisturizer, too! ;)

Needed to Clean graffiti off two of our signs at the building and was able to do so using the spray. Some areas took a little work but The graffiti completely came off

Some of the tiles in my shower started crumbling. As soon as they got roughed up, lost their smooth surface they started to develop black mold. This stuff cleaned the mold off pronto with a toothbrush. Seems to inhibit the mold for quite a while as well.

Used this product on a small area of stamped concrete which it immediately destroyed. Damaged the coloring/sealer on the concrete after a few minutes. I'm sure it is going to be a pretty penny to repair.

This stuff is great and worth every penny. Just spray the area you want and wait five minutes. Then wipe off, I used a sponge with a scrub side for really caked on stuff but really didn't need it. Did each wall of the shower one at a time and it was sparkling when I was done, also did wonders on the sink. I have used other regualr supermarket products that needed either a ton of elbow grease or did not work at all. Krud Kutter makes it easy and according to the bottle every two months just spray back on and that will keep everything in good shape, can't beat that.

This product smells so bad. I think it works fine if you can stand the awful smell.

I bought this to clean my shower tiles. It is wonderful! The dirt and mold just melt away on contact!

This product was very good at cleaning away mold and mildew.
