Sorry Miro,
I'm certainly not wounded by your writing or propositions re cleaning nor your choice to not accept my arguments - As I said - I knew you wouldn't.
In fact I have nothing invested in this discussion except some time.
You don't seem to be able to read what I write.
Perhaps it's my writing or perhaps your reading.
However I'll have someone else read my posts in an effort to find out whether I've missed the mark in my writing.
Such things are easily done on the internet & I'd hate to have written poorly &/or without clarity.
You'd be safe in a knife factory because you seem naturally inclined to miss the point.
I think Lt. Bob had the measure of this matter and I'll defer to his wisdom.
Sadly I don't drink alcohol - not even denatured.
