Very 'convenient'

Bet they got a good crop of tomatoes that year !

Agua Fortis is described by wiki as Nitric Acid.

Agua Fuerte is definitely Hydrochloric Acid as previously mentioned and marked on the label as Clorohidrico.

Just tried a drop in the kettle with a drop water of course because the limescale in this area is pretty bad.
Cleaned it up in a jiff where other concoctions had failed miserably.
Left it in only a minute or so before rinsing as I imagine it could damage the element seals pretty quickly if left to long.


Seperate question, for a Fontaneria possibly ?

It's nine years since I had my gas fired water heater installed and although it's turned up to max. the temperature seems to be dropping off.
Is there any way of restoring it back to its original performance ?

I'm guessing that limescale is the likely problem, but I'm certainly not going to mess with it myself.

yes, my gas boiler gets blocked, I found that agua fuerte un blocked it,

ps I do the kettle trick as well, but be sure to boil it and throw the water away several times before drinking !

It can taint the water a bit.

So how did you go about it ?
Is it a simple straight-forward job, once the cover is removed ?

The best thing for removing limescale in your kettle is lemon.
Cut a couple of lemons into quarters and boil them up in the kettle (I boil them three times), leave to stand overnight and by morning the limescale will be gone and your kettle will smell fresh....it's gentler on the element too!
