Joe, im thinking that you went down the spam internet worm-hole matey, ..likely over exposure to internet pop ups & the like "reduce belly / melt fat, eat/drink this one thing every night" ..etc etc.
Your apple cider vinegar is a pricey number, I use cheap old White vinegar (with bicarb) to rid containers of smells, stop the wife moaning about bacon burns in frying pans (a lifting paste left overnight & gentle scourer) .. just vinegar in beer brewing kit cleaning of stainless steel, as well as dunking & leaving shower heads in, kettles etc.
generally we have between 5 & 15 litres of the stufffor decalcification & high but nigh on harmless acidity as a brute force fixer.
As an east anglian, the water here is harder than a fella on a double dose of viagra, ...the 1980's HW tank & pipes were filled with calcified junk, I took a pipe out to check in the d/stairs loo to check, furry artery clogging, hot water tank was as expected...
Now clean as a whistle, from what others scoff at a low voltage pulsing current wrapped round the in pipe.
The permutti unit (£3 new at auction) was bound & covered with a foam pipe insulater segment, ..it caused a lot of crap to be spat out of taps for 18 months plus, since then no problem, i dip the shower head in vinegar every 3 years or so just to keep the flow A1 from the nozzles, ..before they gummed up in a matter of months, then poured into a bottle for re-use, kettles done via a different bottle, but again only descale every 6 months with vinegar, more if
I can be bothered.I
When it came to a knackered corroded, hw element swap out, the copper tank (had a sacrificial node originally) the element was corroded so far through it shorted, & crumbled upon removal, but the previously calcified tank was as clean as a whistle.
The voltage "seems to" create a slurry state of limescale heavy water, so it still is present on shower tiles etc but thats dried rather than down the drain.
depending on how old your turkish property is, might be time to find a cheap one on turkish ebay they come up every now & again, ..never had a scale jammed cistern since, grit in a syphon fitting, plastic failure etc but that's it.
in fact, 18 yr old daughter was just starting cubs when she experienced plumbing, syphon change, replacement lever valve, cutting copper pipe, smooth, bind with ptfe tape & re-fit ..& check plastic bits compression too..
Hasn't leaked, dripped, or got tight & awkward since, ..she earnt her diy badge for sure.
For you in future, a dry cistern & a plant spray bottle might do the trick as periodic maintainance, I doubt theres much in the way of a silicone "doo-dad" you could fit round that part of the kit to hold some white vinegar in situ? ..a thick childs swim cap is what i might try though & see how it holds as a vineg-oir to get in there.
spray bottle for your shower, ..youve got to love vinegary chips to do that though.
Glass cleaner, tile cleaner, stove glass cleaner ...blah blah blah.
