Skylarlife Home Tiles and Sealant, Rubber Stain Whitnener Gel Apply on Silicone Caulk for Bathroom, Kitchen, Joint Sealant, Rubber

This stuff really works and is pretty easy to apply. Definitely try it if you have mold in your grout of your tile in the bathroom.

Easy to use, just leave on for 7-8 hours and voila! The mold is gone. I had black colored mold that I could not for the life of me scrub off… and enter this product and it’s almost entirely gone! I bet if I did a second round, it would be entirely gone. Smell is bleach like, which I would expect for a powerful product. First 4 pics I posted are before and last 4 are after!

I brought this a long time ago as a precaution. Sure enough, due to some circumstances, I needed to use this around my tub. I'm limted in my functions but I found the application on my tub fairly easy. Only squeezed a chalk line around the tub , mainly on the dark spots. Let it sit over night and when i looked again it was completely white again. WoW! This stuff really works. I did not severe mildew, just a disclaimer. This does give a bleach smell, so airing out the bathroom is necessary. I used up half the bottle as well so depending on the job , additional bottles may be needed for more applications. Overall, I will get more of this on stock, as its helpful to catch , even better than other brands. The best part there was no scrubbing, only wipe down. Try it , really good buy.

It is a great solution for mold and mildew removal! Just apply it on the areas needed, let it sit for 5-6 hours, then wash it off during next shower! Works on grout adjacent to tiles and sealants around shower glass equally well.

We followed directions: surface was dry, left it on for 18 hours. Nothing - black areas in the shower looked exactly the same. I did get a bit on my shirt and it bleached it out immediately so the gel was active, just not where we needed it to be. We can say we tried but otherwise a total waste of $15.

Left it on for over 8 hours, removed some crap but not effective overall.

One review convinced me to buy this for mold under the silicone and grout in my shower. All 4 corners about 12-18” up had some black under the silicone. I was ready to hire a tile person to dig it all out and replace. Someone remarked that she was going to do the same thing, but this gel worked. I did reapply twice late yesterday afternoon and evening. This morning I was shocked at how well this worked! I do not need to remove anything now. Amazing stuff and I still can’t figure how it worked because I did not believe anything would penetrate that silicone or whatever it is. I would encourage you to try this! I regret not taking before and after photos.

Holy crap! I've had a problem with mold in the grout/caulk in the shower of my apartment for the last 5 years! It was like this when we moved in, and no amount of bleach, shower cleaner, grout cleaner, or scrubbing made any difference. Thought this was worth a shot and I can't believe the difference! There are definitely still some spots that might need a second round, but even so I am incredibly impressed. Portions of my tub that have been black for years look clean and white! One of my pictures also includes a window sill we have in our shower, which often gets moldy too, despite constant cleaning. I zigzagged some gel across it, expecting it to spread across, and as you can see, the bleach both cleaned stains beautifully, but also didn't move very much. Perfect indicator of how well this product worked, even if I have to do the sill again to get rid of the pattern lol. I did rinse the gel away quickly after the 6hr wait time, but I didn't get super close to see how well the gel rinsed away. Will update my review if I have any of the issues that some of the other comments complained of. So far it seems to me that this was worth every penny I spent on it!
