WASABI - Rudolf Waldispuehl
I used to use just freshwater but I found out that the tubes getting barnacles and other growth in it due to the constant flow of Saltwater from the fridge pump.
Since 2 year I buy just about 10lt of normal household (cleaning) vinegar. Very cheap about .70 cents per liter at grocery (Mercadona). It is not aggressive and helps to clean out the tubes.
I fill up the Aircon and Fridge lines and let it work over night. After that I flush out everything with fresh-water from the shore and let it in over winter.
There is quite a lot of lime(calc)-dirt coming out with the vinegar. Sometimes I add a bit off antifreeze which is corroding protective as Nick mentioned.
Best regards and good preparation
