I have heard that you can clean the build up that occurs from sea

Acetic acid. Is this true?
Yes, it's true. Distilled white vinegar will dissolve and then prevent
future buildup of sea water minerals in pumps and hoses...not only in
sanitations systems, but in all raw water intake lines.

Use ONLY distilled white vinegar...it's a lot more acetic than cider or
wine vinegars. Plus, it's distilled from alcohol...cider and wine
vinegars are distilled from fruit juice, which can leave a sticky residue.

If you have a serious buildup, you may want to use a 12% solutions of
muriatic acid to clean it out...white vinegar will work, but it may
require several applications, whereas muriatic acid will work a lot faster.

Once you've cleaned out the system, a cupful--two at the most if the
lines are longer than they should be--once a week, flushed ALL the way
through the system (do NOT leave it sitting in the bowl!) once a week
will prevent it.

Distilled white vinegar is available in any supermarket. If it's not on
the shelf with cider vinegar, it'll be in the cleaning supplies
aisle...'cuz although distilled white vinegar has very limited
application in foods, its primarily a cleaner.

You might want to google "white vinegar" to see all the cleaning jobs it
can do.
