It’s a good thing that water and solvent don’t mix. I have a really cool distilling solvent tank. It separates oil from the solvent with heat, leaving clean solvent. This solvent cost a lot but lasts a long time and there’s no expensive weekly service fee.
I let some water based solvent get into my system and it turned into a thick gooey mess. I was worried that I had ruined 20 gallons of $37 per gallon special solvent.
But solvent is less dense than water so it floats on top of water. I manhandled the system onto my motorcycle lift so I could raise it high enough to make siphoning easy. Then I tilted it so one corner would be the low point. Let it settle. Then siphoned the gooey mess out from under the solvent.
While I’m at it I’ll clean everything and mop the floor. All’s well that ends well. Thank you to Howard at CT-Industries for the advice and sympathy.  Howard has the $37 solvent, the other place wants $75.
With science and hard work you can fix any problem.
