If this is a genuine post (and i doubt very much it is) then you have probably ruined everything with white spirit because it's not going to mix with water.
One, you are obviously not reading my posts closely enough, and two, if you don't like it, don't read it, you don't have to try to close everybodys minds down to the possibilities, and third you are in no position to say if anything is in doubt or otherwise clever clogs.
notes: the white spirit does not mix with water, as as now been established (if you'd read the thread properly) and therefore has not 'ruined everything'. What I have to do is skim the top off the tank (probably siphon) and job's done.
