Yes, an acetone wash.
I took this from reddit:
It might seem daunting at first but it's actually super easy. The great thing about the acetone wash is that the blow always remains solid. Peace of mind, you know? Never lose sight of it haha.
Anyway! The most important, absolutely
critical part of acetone washing is making damn sure that your acetone is anhydrous - meaning it doesn't contain water. This is important because one milliliter of water, just
one, will dissolve around two grams of cocaine. If you don't have anhydrous acetone, you'll literally pour your coke down the drain.
There are two ways of getting anhydrous acetone.
- Buy ACS grade anhydrous acetone from Amazon or a chem supply store, either online or brick and mortar, that sells to the public. Easy peasy.
- Make your own. This takes some time. You'll need regular acetone from the hardware store and Epsom salts. Throw the salts on a baking sheet covered in foil and into the over for a few hours at 400F. You now have anhydrous magnesium sulfate. Throw that into the container of hardware store acetone, shake it up, and let it sit for at least 24 hours. The mag sulfate will pull all the water out of the acetone, turn into goopy sludge shit, and sink to the bottom of the container. When you're getting acetone out of the container, don't tip it and pour. Keep it still and pull out what you need with a pipette or something.
On to the procedure. Super easy. You need 15-20ml of anhydrous acetone for each gram of "blow" you want to wash. Throw your finely powdered blow into a glass container (beaker is ideal), add as much acetone as necessary, and stir that shit up.
Grab a medium flow filter paper (couple stacked coffee filters work in a pinch if don't have lab filters) throw it into a funnel, and pour your acetone and blow mixture through it. Don't stress if there's blow left in the beaker. Pour 20-30ml more acetone in the beaker, swirl it around, pour it through the filter. Do it again if need be.
Your blow will be in the filter paper, all the nasty shit will be in the liquid in the container that the funnel drained into. Dispose of the acetone.
Lay out some paper towels, fold up the filter paper with the blow in it, and press it dry with the paper towels.
The last part is the hardest, at least for me. Wait for it to dry. 24-48 hours. You can use a hot ceramic plate or an oven on
lowww heat to speed this up if you want. Make sure it's bone dry.
Voila. Acetone wash!
