Thanks elliott,
yep, this
Intertank with its many fine grooves seems to be a prime example of a "wax catcher"
and therefore obviously needs a combined special cleaning treatment.
But I will not let up until I have found a way out, rely on it.
Therefore I'm going to try the
Pre-soak method (maybe a day or two) with my
1st IT, whereby it actually seems logical that soaked "dirt" can be removed better, as in grandmother's time ...
And maybe the brushing out of the grooves with the
Dremel brush can also be done under water.
