Can You Tell Where I Used It?

Can You Tell Where I Used It?
Wow! I didn’t have high expectations of this but it really works.We just moved into an older home that had been sitting for a bit. Eventually we will retile the shower but until then- my husband said I had to deal with the mold and mildew. So- I went to work trying to find a product that would clean the shower. Ugh! The thought of this stuff touching my skin really gives me the heebee jeebees.After using multiple products without success, I was surprised to realize that this one actually works. Of course, I always try each product in an inconspicuous place. As you can see by my photo, I think it’s pretty clear where the product was used and where it wasn’t.I took one star away for three reasons:-First, if you have a larger area like I do, you’re going to need a lot more than this tube can give you. It’s kind of expensive for how little you get (but I’m desperate to take a relaxing shower so I’ll pay it).-Secondly, there is not tip for this tube. That was a real disappointment for me as I couldn’t more accurately get in between tiles. This makes me feel like a lot is wasted and it’s already expensive.-Lastly, you have to let it sit for up to 6hrs. Ugh! This is difficult to accomplish in a house of 6. Yet, none of these negatives take away from the fact that this formula works and I’m buying 3 more now to finish the shower.

    I was skeptical since we've tried everything to clean our grout, but this stuff really works! In the past we've tried the normal sprays, brushes, and even attachments for the cordless drill. None of that really worked as it was clear that our grout was just stained.

    This stuff was pretty easy to use and really cleaned the grout much more than we expected. You use it by applying a thin bead on the grout lines. It seems to be a gel-like bleach, so it stays in the grout lines pretty well. And you wait about 4-5 hours before washing it off. Pro-tip, the tip of the tube twists. I didn't realize that at first so I cut my first tub like a tub of caulk and it was quite messy.

    Anyway, we tested this on a small 6" strip of our grout and washed it off 5 hours later and were quite surprised at how clean it appeared! So we did the rest of the shower the next day. I have to say the grout looked almost new after applying this and rinsing it, but there are a few cons.

    For the cons: rinsing it was a bit of a pain. Since it's like a gel, it took a while to rinse off. I preemptively purchased a handheld shower want and I'm so glad I did. Because I don't see how you would rinse this stuff off without one - so I highly recommend getting one. Even with that it still took a while to wash it all out.

    Also, another con (or pro, depending on how you look at it), is it seems to also have eaten away at some of the caulk around the shower. That ended up being ideal, because our caulk was also pretty old and dirty and in need of replacing. So since it starting peeling up, I ended up buying a scraper and completely removing the caulk too and re-caulking the shower. So while I said this was a "con", it actually made it easier to get the caulk up and now we not only have clean grout, but also fresh caulk.

    One thing I noticed after cleaning the grout is that we had a few "pits" in the grout lines. I'm not sure if this was due to the cleaner gel or if it's just from neglect / previous scrubbing of the grout. But I found some easy DIY grout replacement at the hardware story so I could clean up those few areas.

    All in all - this stuff was totally worth it! That said, what I expected to be a clean and rinse situation turned into much more work for me to fix some grout and caulking throughout the entire shower. But it very much worth the few hours of work that I put into it.

    This is a thick gel cleaner that you apply to grout or caulk that is mildewy. Just let it sit for a few hours and then wipe it off. It truly works! Caulk that I thought was permanently grey/black turned white again. It’s so quick and easy to apply with no scrubbing. It does smell like bleach so be sure to ventilate the room and keep sensitive people or animals away while it does its work. Depending on how much you need to clean, you might need more than one tube. I used up much of my tube on a couple lines along the bathtub.

    I've had dirty, mildewy grout in my tub/shower area for a while now. Nothing I've tried before seemed to get rid of it until I found this stuff. It really works! I finally found something that works! I took a couple of applications to clean up the really bad areas. I used the whole tube & plan to order more. I subtracted one star for the tube design. The only thing is I wish it had a slanted applicator tip. There's just a round hole under the cap. This is not very precise for getting the gel where you need it. I'd like the tube to have a small, slanted applicator tip. Other than that, this stuff is great!

    5.0 out of 5 stars Really works well!
    Reviewed in Australia on July 15, 2024
    I have bought this 4 times now every time I do a periodic shower grout clean.
    Works really well - better than any other 'squeeze on rinse/wipe off' products I have tried - dissolves mould and other dirt/grime without issue after leaving for 6 hrs. Prefer to use this method, rather than using some cleaning products that require some scrubbing...which can wear down grout over time.
    It does require a 3mm film applied to the areas you are working on. So need to take this into consideration if doing larger areas. With one tube, I could do a shower room floor with 18cm square tiles, and about the first x2 levels of wall tiles (see attached pic).
