Soft Scrub Sapphire Water Duo Cubes - 2ct

Just bought these for our toilets, i put one in each tank.the first few days it was so dark blue, not even a week later there isn't much color left. This is a 2 person family one person for each toliet.. why, not a good buy.

I had my hope up it said safe for septic. Well got home followed the instructions place furthest from the valve. Wasn't impressed with blue but if it keeps bowl cleaner I'm game. Well no more bluish (lol). Dropped another cube after few flushes back to light blue water again. The bowl had to be cleaned several times sames as before. Cubes were no better on preventing or helping with cleaning. Was going to use up the package and throw the third cube in. Lift the back of the tank and was shocked! There was slime on the inside on the tank OMG. Needless to say I cleaned up before I even thought about snapping a pic. The military cleaning got the best of my cleaning. So far this is the FIRST PRODUCT OF YOUR THAT LET ME DOWN.

i bough this less than 1 month ago. i put in toilet and it wasn't turning blue, eventually after approx. 1 doz flushes, there was very very pale blue water in toilet bowl. yet on my 2nd toilet in the home the cube activated after the first flush. not impressed with this product, too inconsistent .

Up to 8 weeks, they must have meant 8 days. It's gone pretty quick. Don't buy this.

Only lasted a week. It starts out super dark blue, and by day 7 or 8 it was gone.

These cubes are supposed to last up to 4 weeks, maybe with one flush a day! Purchased some a week ago and one barely lasted 8 days. I guess 4 cubes would last 4 weeks!

The commode I place this product in is used only a few times a week. That is just about how long it the cube lasted. As a longtime Soft Scrub user, I expected better results from these Duo Cubes. It was barely worth it as a BOGO item at our local grocery store.

I had really high hopes for this product. The first few weeks were blissful- sparkly clean, gently scented blue water and a clean bowl- exactly what I bought the cubes to achieve. Then one day I noticed some weird greenish floaters appear in the bowl after flushing. After several more days of ever-increasing floaters and suddenly weak flushes, I took the lid off the tank and was greeted with what can only be described as an algae farm. The toilet jets were clogged with the stuff, all of the toilet innards were coated, and the sides of the tank were fully covered. I’d never had this issue before, ever. Apparently basic (as opposed to acidic) environments are the perfect host for nasties such as algae! It was taken weeks to mitigate this grossness.

It only lasted a week, very disappointing! Will not be buying this again!

It reads, last 4 weeks for one cube notso.only one week and I live alone..

I recently purchased this product. On the positive side, I appreciate the color of the water in the toilet bowl after each flush. However, there are several drawbacks that have deterred me from giving it a great review. Firstly, the tabs don’t last long, which is inconvenient. Secondly, the tabs don’t effectively kill the bacteria in the toilet tank. Lastly, the colored water only partially covers up the dirt in the bowl, and I still have to clean it daily with a toilet brush. In conclusion, this product is a waste of my money, and I won’t be purchasing it again.

These cause some type of film or residue inside the toilet bowl that both looks gross and smells awful. It's like it traps every disgusting thing that goes into the toilet and hangs onto it, causing the entire bathroom to stink. Can't say if it's our particular type of water (city water that tends to be a bit hard), but I find myself having to scrub the toilet nearly every day to get rid of the residue and smell, which defeats the purpose. I ended up fishing the tablet out of the tank and tossing the rest of the package.

These do a great job at keeping my toilets clean, drag and sanitized. Good price as well.

Bought 7/1/25…dropped in tank 7/3…product dissolved by 7/7 SMH. A cube DEFINITELY does not last 4 weeks!!! Misleading packaging. The only two positives (hence the 2 stars) is that it smells amazing and the cubes aren’t individually wrapped.

The Soft Scrub Sapphire Duo Cubes are a quick, low-effort way to keep toilets fresh and visually clean between deep scrubs. In a home with seven people and multiple bathrooms, this kind of passive maintenance helps a lot. You simply drop one into the tank, and it starts releasing cleaner with every flush. It turns the water a light blue shade, which makes it easy to see when it’s working and when it needs replacing. There’s a mild clean scent, nothing overpowering, and it definitely helps reduce buildup and odor. However, these cubes don’t replace actual toilet scrubbing. You’ll still need to clean weekly, especially in high-use bathrooms. But they do keep things fresher and reduce that “ugh, someone forgot to flush” moment. At two per pack, you’ll want to buy in multiples for a household our size. They’re inexpensive and functional — a small, helpful add-on to a bigger cleaning system.

This lasted less than a week and it left gross stains on my toilet both times I used it. It’s cheap and the price gives it away. I do not recommend buying at all.

Clean scent BUT leaves a “blue” discoloration which is hard to scrub off.

They smell alright but only seem to last a few days.

lasts longer than the scrubbing bubbles and better quality

This should have been shipped separately and never combined with food items. Everything in the box smelled like cleaning solution!
