Toilet Bowl Cleaners ?

The stain is from stuff in the water. I'd try CLR if no one give a better reply on exactly what it is and how to eliminate it.

For normal cleaning, I use a glug or two of bleach and brush it around but I never get those blue stains.

Suggest a cleaner that works other than the one that works? You might try phosphoric acid. You can find it in Home Depot around the concrete supplies. It's used to etch concrete but is not as aggressive as hydrochloric. It's sometimes used to descale coffee makers. Even vinegar might work but I wouldn't count on it.

I seem to recall these cleaners contain hydrochloric acid at half the strength of what is sold as Muriatic acid or about 35% HCl. They also seem to contain a viscosity booster and dye to cling to sides of toilet. You could cheaply make your own but be careful the strong acid fumes and dilute it where you will not have to breathe them.

Something wife used to use Iron Out which contains sodium metabisulfite and sodium hydrosulfite. It was quite effective. I note that the metabisulfite does not seem to work alone as I tried stuff left over from my wine making days used to help yeast keep clear of bad strains.

We havea tried CLR, chlorine bleach, and a host of other toilet cleaning products, none of which worked. We now use ZEP Commercial acidid toilet bowl cleaner. It's cleaning ability is nothing short of amazing. However, the container does not specify what type of acid it contains.

Those usually scratch the porcelain.

No, but the MSDS does....

HYDROCHLORIC ACID; muriatic acid; hydrogen chloride; HCl

The last bunch are surfactants.

It might be worth buying a pound and seeing if the sulfamic gets rid of the mineralization by itself. If not, throw in a little HCL.

Thanks for the valuable information. We are very careful with it and since it's the onlyh product we've been happy with the results, we will continue to use it.

We were aware that it contained acids, but not the breakdown you supplied. We have always used laboratory grade chemicala resistant gloves.

Sorry if this wasn't hepful to the OP.

Does the container say anything about septic tanks - safe?

Blue means copper.

Maybe this link will help:

It does not mention septic tanks, but we don't have one.

Bon-Ami. Doesn't scratch.

I think there is a special product for copper stains but I don't remember what it is, Zud?

Zud will take most stains out. We always have a can around, but it doesn't work on the type of toilet stain we have.
