Strongest way to kick toilet limescale

Purple Mountain

Living in a very hard water area.
We have an outdoor toilet in the garage that isn't used that often. It gets cleaned sporadically, hate to say it's neglected.
Anyway, there's a big build up of limescale now in the toilet bowl. It's rock hard like cement and a film of iron on it too.
I'm suspecting it's causing this toilet to block sometimes now so I need to get this limescale shifted in full both in the bowl and possibly the back pipe I suspect.
Please tell me the strongest product I can use!

Public sewer or septic tank?

Septic

Then you are limited because it will kill all the bugs in the septic tank and lay waste to the percolation area with what I was going to suggest.
Best get a water softener and take a sledge to it

Put the water softener directly on it?

What about a massive dose of vinegar put directly on the limescale if I drain the water off?

Could you use the Harper Power Plus in the black wrapper on it PM?
If you can , use the full bottle on it , leave it for 12/24 hours , that usually works .

There is stuff you can get called Loo Boss. I get it in the Co op Superstores. It will do the job.

You need to use the plunger to push the water down past the U bend, then let the bowl completely dry and then apply whatever product you are using and use toilet brush to scrub it in. Do this at night and leave for as long as possible before flushing. Do this a few times and it should do a good job

If you live near a farm supply shop, get a 5 litre can of milking machine descaler, and put half a litre in the bowl, it's the best product for what you want to do.

Will that upset the natural bacteria in my septic tank?
Thank you for that tip!

That's why I asked IF the OP could use it , TPT, I wasn't suggesting to use it if it wasn't suitable for use with a septic tank .

I didn't know it was as clear as mud to most people not to use it , I wouldn't have suggested it if I had known .

Limescale is best attacked with acids if looking for an easy cleaning method.

Slow, but effective, is vinegar which has acetic acid. The higher the acid percentage, the faster the dissolution. Put a cloth over the limescale and drip vinegar over it over a few hours/days depending on how bad it is. It will go away eventually.

Fast, but not too septic tank friendly, Nitric acid. Again, put some cloth (wet toilet paper this time) over the limescale and wet it with Nitric acid. It will dissolve fast - so will any clothes your wearing it touches as well as skin irritation/burns! Be careful. I use Nitric for lime deposits but I use it with gloves and wet wipes I neutralize with a base afterwards - no acid goes to drain.

Medium and possibly safest. Muriatic Acid (Dilute Hydrochloric acid). Since dilute, it's a bit safer than Nitric. You might find it in a builder provider as a patio cleaner for removing cement smudges.

Hope this helps!

Vinegar. I use it on the kettle. Works great. Get the water out of the pan first and pour a litre of vinegar in. Leave overnight.

All of the above points to replacing the bowl and getting a water softener.

Will using excess vinegar have any impact on the eco system in the septic tank?

Vinegar and lime produces carbon dioxide bubbles, water and a calcium salt which is used in some food products. A few litres will be safe, as long as you don't put an enormous volume down the loo.
