Fluidmaster 8302 Flush Sparkle Bleach Replacement Cartridge Save 22% Off

• Installs Easily
• Provides cleaning solution directly into the bowl without harming the toilet tank components

For years we used chlorine tablets in the tank and all they did was damage the internal hardware in the toilet. When refurbishing all three toilets in our home, I saw these units and decided to give thema try. Fantastic product and for three months they have kept the toilets spotless. I don''t like the "Blue" as they don''t keep the bowls clean and the "Enzymatic" cartridges are for septic tanks. The bleach tablets are my favorite.

Buy Fluidmaster 8302 Flush Sparkle Bleach Replacement Cartridge Now

I have been using the 8302 bleach version of FluidMaster 8300 Series Cleaning system for years. I have a well water supply in which the water is chlorinated and then the chlorine is removed by a whole house carbon filtration system. Hence, no chlorine is present in the water supply in the house. The 8302 chlorine refills have solved the toilet bowl cleanliness problems, as well as preserved my toilets'' internal plastic parts. The softer the water and the more frequent the toilet use, the more of these refills are required.

Here''s the big tip if you are handy, this is easy; if not, it''s still not very hard. Pool and spa supply stores sell chlorine tabs for spa chlorinators which will fit inside the FluidMaster cleaning system. Example: 100 250 tabs for $20. All you need is a vise and a few scredrivers to secure the refill cartridge and pry off the end cap, which is fitted pretty tight. I use a suction base swiveling hobby vise ($25 or so). Insert new tab, replace cap, done. Have some spare cartridges on hand and refill them all at once. I have replaced the tabs in this manner at least 15 to 20 times per refill cartridge. Eventually you will have to replace the refill cartridge, as your prying efforts will gouge the end cap too much for subsequent use, and the cartridges themsleves become brittle over an extended length of use (years). I have reduced my costs using this method to practically nil.

Amazon''s photo with this item (as of November 2008) is of the wrong product. The photo shows the blue refills, which are worthless unless you just like blue water. This product, Fluidmaster 8302, is bleach--not blue--refills for their Flush ''n Sparkle cleaning system. I added my own "customer image" of the correct product; look closely and you can see both "8302" and "bleach" clearly printed on the tab at the top of the box.

The bleach refills are the best toilet-cleaning product you can buy. Even if the Flush ''n Sparkle system you installed in your toilet originally had a blue cartridge in it, you can use bleach refills, which I strongly advise.

Their only disadvantage is that you can''t tell just by looking at the water when the cartridge is empty. But removing the cartridge every few months to see if it''s empty is a lot easier than scrubbing the toilet bowl every week, which is what you''ll be doing if you use the blue cartridges.

Want Fluidmaster 8302 Flush Sparkle Bleach Replacement Cartridge Discount?

I am writing a review of three toilet cleaning systems I''ve bought here on amazon:

Fluidmaster:

Uses a cartridge containing a chlorine based tablet.

Cartridge is not meant to be refilled.

Chlorine odor noticeable in the bathroom.

Cartridge can be modified (I used a dremel) so it is easily refilled.

NeverScrub:

Uses a cartridge containing a chlorine based crystal.

Cartridge is not meant to be refilled.

Chlorine odor noticeable in the bathroom.

Kaboom:

Does not use a cartridge. Bromine tablet refill inserts directly by unscrewing a cap.

No odor noticeable in the bathroom.

All three of these systems work the same way and all are really easy to install. All of them put a toilet cleaning chemical (tablets or crystals) in-line between the water fill valve and the toilet bowl fill pipe. All of them prevent the chemical from getting into the tank water (so there is no damage to the plastic parts in the tank). All sell refills for their systems. All keep the toilet bowl equally clean for about 1-3 months depending on how often it is flushed.

Amazon also sells Pool/Spa Cleaning Chlorine and Bromine tablets, which as far as I can tell do just as good a job keeping the toilets clean as the refills but at a fraction of the cost. I have tried all of the following, each of which provide enough tablets to keep all the toilets in the house clean for 10 years and they are all very cheap:

Kem-Tek 177:

The tablets fit well in the dremel-tool modified Fluidmaster cartridges.

The tablets fit well in the Kaboom.

The bathroom has a slight chlorine odor.

Spa-Kem 267:

The tablets are too large to fit in the Fluidmaster cartridges.

The tablets fit well in the Kaboom.

No odor.

Tropi Clear:

The tablets fit well in the dremel-tool modified Fluidmaster cartridges.

The tablets fit well in the Kaboom.

No odor.

Chlorine and Bromine are fairly equal in cleaning ability. Chlorine has that chlorine odor. Bromine is broken down by sunlight. Which is why, on a sunny day, outdoor pools use chlorine. But at night, or indoors, or on a cloudy day, they use bromine since there is no smell.

Summary. The Fluidmaster system works but the cartridges are expensive. To refill the cartridges easily requires a small modification with a dremel tool. The cartridge is too small for any tablets larger than 1 inch in diameter. The NeverScrub system also works but the cartridges are expensive. What I am using is the Kaboom system with the bromine tablets (either the Tropi Clear or the Spa-Kem 267) as they have no odor and clean just as well as the chlorine tablets.

First of all, Fluidmaster is a very fine company and the cartridge bleach concept is a wonderful way to keep the toilet clean and, at the same time, not damage the components in the tank.

However, the price of at least $5 per bleach cartridge and their lack of ready availability is a negative. Here is another approach for the handy guy (or gal).

Carefully pry off the BOTTOM cap of the empty cartridge using a thin flat blade screwdriver. Hold the cartridge firmly while doing this. Once it starts to show a gap, use a larger flat blade screwdriver to remove this cap.

Go to Lowes and buy the 3.75# bottle of Aqua Chem 1" x 1" chlorinating tablets. Price is about $23. Put three of these in the cartridge and press the cap back in place. You are ready to go. Just use safety precautions handling the bleach.

If you screw up the "O" ring at the top of the cartridge, get a new one at ACE hardware for about 70 cents.
