I used some all purpose thinner to clean out the tubing of a refrigerator so i would like to know what is the best solvent i could use to flush out the thinner completely?
"All purpose thinner" tells me nothing about the chemical composition. I can only guess, which would be a mix of toluene, xylene, naptha, MEK, white solvents, and many other waste or non spec solvents left over from the solvent distillation process. I do not know what you were trying to remove, what the oil type is, or if this solvent removes it or has reacted with it. So it is difficult for me to recommend a solution for a problem I do not have all the info about. With that said, most evaporative type solvents will reduce down to trace levels with a long hard nitrogen (or dry air) blow for about 20-30 minutes in a modern automotive component. The vacuum process can then be used to flash off any remaining trace, and this can be confirmed with the use of a micron gauge.
One problem being encountered with 'fast' evaporation chemicals is that this type chemical does not perform an adequate removal of sludge, esp in the PFHE/PFHESC/6MM PIC condensers. The flow characteristics of these units and the flush procedure allow for excessive vaporization and evaporation of the flush chemical. This rapid change of state reduces the ability to remove semi solid/solid materials from the component being flushed.
Liquid based flushes tend to remove more debris and perform better. Removal can be a challenge,but can be accomplished with air/gas purging.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
