The tolly used to extract freebase meth from the reaction fluid should be washed before gassing or titrating. No need to wash it before using it to extract the freebase meth, but it should be washed after that.
Same with charcoal lighter fluid, and camp fuel. You can prewash Coleman's to get some of the antioxidant out, or you can buy a different brand of camp fuel that does not have the antioxidants.
A straight alcohol pull of today's deredded 30 mg pseudo tabs will not yield pure pseudo. The assumption that the pseudo you get with your method is gakk free is erroneous.
The fact that the salt in your evap dish dissolves in alcohol suggests that it is not NaCl. The salt you have was formed when you titrated a mixture with polymers from the pills in it. I have had this happen before. I recall having similar problems with one of the orange gakks when it was introduced. I had a small yield of excellent meth from a first pull, and nothing but salt after that. One of the polymers holding your amines is ambipolar, and will salt out of the nonpolar extraction solvent. Or so I suppose. Your pill extraction method is substandard for the newer gakks, and if you solve that problem first you should not experience the same problem again.
Do the non-polar washes of the reaction fluid before basing it, and wash the extraction solvent before gassing or titrating. You should do this as a matter of course, and it will improve the cleanliness of your product.
I discussed these washes in Post 428410 (https://www.thevespiary.org/talk/index.php?topic=8697.msg42841000#msg42841000)

As to the ratios to use in the fire extinquisher, I will not hazard a comment. I haven't done a reaction that way and cannot say from personal experience how any set of ratios work under those circumstances. As to the ratios I use, see Post 534545 (https://www.thevespiary.org/talk/index.php?topic=8648.msg53454500#msg53454500)

It's unlikely that a fast easy pill clean will be effective enough to obtain pristeen clean feed.
The best way to shave any time of any extraction method is to become as familiar with the procedure as possible.
This involves conceptualizing and then practice.
For that there is no substitute or shortcut!
Shiny reds contain a membrane coat in between the dye and the pill surface and are usually easy to de-red with just acetone and h2o rinses!
Don't let the h2o cut into the pill surface or you risk activating gaaks.
The dull red pills don't have this membrane and make de-redding a bit more difficult.
But as Jacked recently pointed out in another thread...the dyes today contain filter cloggers and are more syrupy than they use to be a year ago+.
