Question: I dont think there is a refill tube in my toilet bowl. What can I do?
Document: I have been using KABOOM scrub free toilet bowl cleaner for several years. It works better than anything - it keeps the bowl clean for 30 days then all you do is put in a refill.
Been using the Church and Dwight toilet bowl cleaner for a few years and they work well. There is no magical way to find that the refill tablets are running out other than to look under the lid of the water tank and see if the tablets need to be changed.Would also be better if there was a pack that contained more than one or two refills as we have three toilets.
i put this on all our toilets so i dont have to clean the bowl. was living with my sister and the upstairs toilet  hadn't been touched in a while. put one of these in there and the improvement was amazing. i tell everybody to buy them, too bad i cant find them in stores.
I am really impressed with the KABOOM Toilet Cleaner System. I think the refills are a little pricey but considering they are good for about 3 months it still is a good value. I have recommended this system to other family members and they have had good results as well.
I've been using Kaboom for years and they do a terrific job. But, it's difficult to find the refills in the store.My only complaint about this product is that there's a slight chlorine smell. However, unlike the tablets that sit in the bottom of your tank they don't eat up the seal between the tank and the bowl. I get two to three months out of one refill package - your mileage may vary.
This product is the best I have found on the market. These are refill disks that easily slip into the filtration device, made by this same manufacturer, for your tank. The chemical disks keeps the bowl spotless for months without scrubbing. It gives off a very slight chemical scent, but not offensive; I have a very keen sense of smell, and is not a bother. We all hate scrubbing, and yet scrubbing products are generally the only option that you will find in any stores.
I gave this 4 stars because it is not perfect but is still the best product I have seen for this purpose. Occasionally, a scrubbing action may still be required, however, this Kaboom system has many benefits including not putting chemicals into the tank which damages the flapper, it is very easy to install, it is very easy to refill, and significantly minimizes the times when scrubbing is necessary. It also seems to keep the water channels into the bowl clean and these channels are near impossible to clean once stained.
I purchased two of these Kaboom toilet cleaner systems at my local grocery store but they no longer have the chlorine bleach refill tablets in stock. I am grateful I found a source for these here on Amazon.
This is the refill. There is a larger 'kit' that you will need, if you have not used this before. The kit is simple to install (at the very top of your tank, right under the lid). We have extremely hard, well water, which is the most challenging type when it comes to keeping the bowl clean and free of mineral rings and residue. This product works 100% on ridding these issues!
I am saving almost $4 by ordering it on Amazon. I am so happy to have this product in my arsenal of cleaning supplies and I think you will be too!
