These little tablets are amazing!
These Eco Turtle tablets are great for cleaning my shower. I tried bleach, bathroom cleaner, nothing would clean the yellow mold of my brand-new bathroom despite repeated efforts. I even had to re-silicon twice. My secret, for those who are reading this is this: First spray silicon with cleaning vinegar (not regular as not strong enough) let it sit for an hour or 2. Then spray on top of this with Eco Turtles Bathroom spray, again spray liberally onto the silicon and get a toothbrush onto/into the mold then wash off, you can do this during the shower but I usually spray before I turn the water on. But this method has thus far saved me from another re-siliconing and this is in my children's shower, they do (hopefully!) wipe the water down with a squeegee which is also highly recommended, water just attracts mold and dirt. I spray with vinegar every 3 weeks or so but every week with the Eco Turtles and toorhbrush.
My two-cents worth so good luck but can recommend this product!
