It's simple.
1. Put about a quarter cup of bleach OR liquid Lysol in the tank for half an hour. Do NOT MIX ANYTHING WITH BLEACH OR DEATH MAY RESULT!!!
2. Turn OFF FILL VALVE. Flush
3. Fill small bucket with the same solution and recommended amount of water for typical cleaning.....dilute.
4. Wipe with rag.
5. Turn fill valve on.
The time I took to write this your problem will be solved.
None of this will harm the seals, however you can't leave bleach in the tank for long periods.
Ttt
that is exactly what i did.. alls clean now...
Glad to hear that.
I just checked in for a moment to mention one one more quick point.
The bleach issue is important to pass along to the family because it's not common knowledge that the gasses (chlorine) that are put off when mixing with other household chemicals is one of the most dangerous ones custodians and homemakers face. It's easy for them to remember if they think of Clorox / chlorine. I almost accidentally bought the farm as a teenager mixing it.
In my climate, mold grows quickly too. The damp environment of the tank is even worse, especially if the water isn't chlorinated city water. White vinegar can be used in the same way that I described. The acid should not be left in the tank very long as it will dissolve the porcelain and cause pitting. The same method is good since it kills mold too.
As a preventative you can use Borax from time to time.
1. Dissolve a quarter quarter cup in warm water.
2. Pour it into the tank and mix.
It should not hurt anything, but if you ever see mineral deposits, follow up with vinegar.
The boron in it kills mold as does any residue. It can also be used in place of bleach if any household members are sensitive to chemicals.
Have a great week!
