New build and toilet stains

Well it sounds obvious when you put it like that :blush

Armed Forces married quarters march-out trick:

Use full box of Oust washing machine/dishwasher descaler.  Tip both sachets into a half bucket of hot(ish) water, stir until dissolved, then tip contents of the bucket into the loo and leave for as long as possible (preferably overnight).

If one needs replaced they’re ok with that, but 3 means backtracking to it’s a limescale problem. 

Possibly because one might lead them to think a manufacturing issue was plausible, all three in the same property tends towards an environmental issue (aka what's being flushed)?

All three toilets are likely to have the same water supply, ergo limescale from the water is a prime candidate.

Or all 3 toilets were from the same faulty batch?

It's possible, but as mentioned there is barely any limescale on the sinks, taps, dishwasher, etc.  Not to mention I would expect my cleaning efforts to date to have shifted it, if it was limescale.

Limescale? Most probably tile grout put down the wc by the builder’s tilers.

I guess anything is possible, but what would the chances be of the entire toilet bowl being covered in tile grout?  We're not just talking odd patches, or below the toilet water line, but the entire bowl.

The problem with the vast majority of cleaning methods is that they only really clean up to the height of the water line / u-bend.  In this instance the entire bowl is staining, right up to the rim.

Possible, but then the manufacturer would (by now) probably be aware there was a batch fault and not quibbled over replacing all three (this is why I suggested the OP contacted the manufacturer in the first place).

The odds of three toilets - and only three - manufactured around the same time having manufacturing faults affecting the quality of the glaze, and all three ending up in the same property, must be vanishingly remote, although not impossible.

Hence my guess the manufacturer suspects an environmental issue is the cause.

There are other plausible scenarios though.

has anyone mentioned trying a can of coke?  without the can of course.  Or actually the coke out of the can and into the pan.

At the risk of upsetting those of a sensitive nature..... urine also contains a cocktail of minerals (e.g. why some people get bladder stones).  Some of these can add to or alter the deposition of minerals from the hardness in water.

This, plus the length of time urine/water can hang around in a toilet bowl, is one of the reasons why 'toilet limescale' is often the main problem in a household with moderately hard water.

At this point the toilets look spotless, to the eye they are also smooth looking.  But they lack the deep gloss finish you would expect from glazed ceramic, especially if you feel the inside with your finger.  They are certainly better than they were after all the cleaning and polishing, but the fact they still stain indicates that one way or another the surface is still porous.  I am truly baffled as to what the issue is - I really wish it was limescale because it means I could clean it off.
