I'll replace that metal hose and head next time it blocks. But think 6 months seems excessive, aren't they just covering their arse sobthey don't get sued. Who would do that on their own shower every six months!

Getting this stuff in eyes - limescale remover, sodium hypochloride etc. Wouldn't filling a sink with water and putting whole face in be best action.
I guess limescale remover is hydrochloric acid. I heard hydro FLUORIC acid is even more dangerous. It enters bones or something and is really dangerous. Think it's used on bricks.
There are numerous acids available. Citric acid crystals are often used in the kitchen, and my coffee machine uses a lactic acid descaler.
Some acids will remove chrome plating from copper and brass, and are used for that purpose in the refinishing trade. You sometimes see in public WCs where this has happened inadvertently.

The medical advise is flush the eyes with 20 litres of water at 7.0pH. Then check the pH of the eyes. If it is not in a normal range, repeat flushing.
That is why emergency eye washing facilities have running water.

After spilling on garage floor put plastic container in metal bucket with tool to weigh it under.
Back to gloves tend to throw mine on dash board to dry before off but reckon if I've been using chemicals (weed killer) etc then best not to as could breath some in

How come you use so much weedkiller? Just wondering.
Look after a block of flats and there's always weeds on the patio, block paving and this pebble thing they have. The weeds in beds I usually just turnover with a hoe and as they're uprooted hopefully they're just die. Weeds everywhere. It's only one day a week. But don't want this stuff affecting my health. Use resolva. At very least dust mask and gloves, don't u think?

Cheers, now makes sense as to why you use it so much. Yes, I'd use a mask and gloves. Spraying gets everywhere.

Assuming home use and not on business scale 
Get a gallon of 'white' (Distilled Malt) Vinegar, half fill kettle bring to near boil - when the chuffing starts - switch kettle off before it ejects hot vinegar from spout, leave for 20 mins redo the heating, pour hot vinegar into suitable container - drop shower head in and leave for half hour or so - Job done - kettle and shower head.
Filter vinegar - allow to cool, replace in container, reuse cleaning purposes only.
Sarson's widely available for around £5 for 5 litre container.
Need stronger ? Citric Acid 1kg - 100% Pure Food Grade, around same price as the vinegar. Use around 5% by weight with (hot) water, buy, for example, from Amazon.
Take further advice regarding disposal.

Would suggest you read the instructions."strong chemical" is not very informative.gives no idea of ph,acid alkali etc..
Went on a job to remove a pump from a yogurt manufacturer once. Young bloke, (early 20's or so), takes us to the pump house and says it's number 3 pump. He then goes off to find some lifting tackle and leaves us to it. Isolate electrics and feed/flow pipes remove the pump complete with motor etc and we are carrying it the steps with a steel bar through the eye bolt. Just as we got to the top the foreman steps through the door and sees us. He literally exploded!
"What the **** do you think you two are doing? Where's your PPE? Why aren't you wearing goggles and a full suit?" etc, etc
Turns out they flush the pumps with Hydrofluoric acid after each batch run and to work on the pumps you have to wear a full HazMat suit which was a rubber/neoprene thing that covered you from head to toe. Also had to have full goggles with a full face visor over them. Not one bit of skin was allowed to be showing. He then made us get kitted out in all this gear before going out the door with the pump in case his boss saw us. Talk about sweating like a pig! We only needed to walk about 10 steps to put it on the wagon! Every step made the suits expel a bit of trapped air so it sounded like we were letting rip with every movement with the consequence that when we came to take it all off it had literally vacuumed itself to every contour of our body so was like trying to peel a layer of thick skin off!
Young lad got a right rollicking in front of us and felt sorry for him but that was there rules so we had to obey them.
BTW, if the acid is not flushed out the system it will corrode stainless steel over time, hence the reason we were removing it to replace the bowl and impeller.

is the only one I know that will eat through glass.
Reminds me of a job I did many years ago.
Asbestos strippers had removed some insulation from a length of pipe.
The site was in the middle of nowhere, and it was pitch black. Military.
I eventually found it, and was allowed in.
As was / is the usual, the assy strippers had only done half a job, some we ended up grubbing around in the soil floor of this building with our bare hands, getting the rest of the insulation out.
When we'd eventually finished and were going back through the gatehouse, the guy manning it commented that we'd been a long time, and he'd hoped that we hadn't been messing with the soil......
Because they used to manufacture mustard gas in that building, and the whole place was contaminated.
I spent the next week expecting my finger nails to fall out!

Even that is a seriously dangerous thing to do with some chemicals and could leave you blind or burned
