I added baking soda to my sugar wash to try to clean it up but my hooch is blue and smells terrible. What have I done and can I save it?

Its a definate no no to add bakeing soda to a wash or mash. Its great to add to stripping run or any run that didn't come out as nice as espected and then run again.

No, from all I have read it is not salvagable. Start over and use what you have for ant killer, weed killer, charcoal starter, window cleaner or whatever.

Sorry to give you the bad news. But like the rest of us, you have learned a lesson the hard way."

"Thanks Mtnwalker,
Iguess I should have read into that further. It really smells funny but it looks cool."

i posted your question on another forum.this was the reply.

Hi Hifa,

From what I remember, filter it thru carbon then dilute it back down to below 40% and re-distill. What you did was add to many nutrients in the form of nutrients and allowed the wash to become to alkaline before distilling it. Higher acidic washes will prevent this.
See below:

Blue Spirit

Sometimes the spirit may get a slight blue tinge to it. This is usually a sign that you've used too much nutrient in the wash. Mike explains ...

I [previously] replied, saying it was probably due to copper salts coming from acid wash. I WAS WRONG!!!!

In fact, I've learned that it is just the opposite! Acid washes do not corrode the condenser (unless, perhaps, they've been allowed to sit far to long and have gone acetic), but neutral to alkaline ones DO. Heating an ALKALINE wash, particularly one with lots of nitrogen-containing compounds that have been put in as nutrients, liberates ammonia, which corrodes the heck out of reflux coils and dyes the distillate a distinct greenish blue.

The Upshot: if the WASH is turning blue, it's probably due to acid wash corroding a copper sheathed element or a copper boiler, but if the collected DISTILLATE is blue, (and probably ammoniacal, but not always), the wash should be acidified!

Turbos contain a lot of nitrogen-containing compounds, and at neutral to high pH, these can liberate free ammonia. At low pH, they are bound up with the acid as salts, and do not liberate ammonia. So, by adding nutrients to an already nutrient rich turbo, you can inadvertently push the mix over the line and get ammonia with your distillate.
Schweitzer's reagent is cuprammonium hydroxide, and is formed when copper hydroxide dissolves in a dilute ammonia solution). It is a deep blue colour, and is particularly known for its ability to dissolve cotton. The chemist who first discovered this property was Eduard Mathias Schweizer (1818 -1860), so it seems that it should really be called Schweizer's reagent.

It forms in stills when ammonia released from alkaline washes (nitrogen source may be plant material or yeasts) reacts with copper hydroxide formed by the action of steam on copper oxides coating the inside of copper columns or components. It may be avoided by ensuring that the liquid in the boiler is slightly acid (pH less than 7).

HTH.

"Good idea Just You!

One suggestion though, dilute to 40% first, before filtering. Perhaps add some citric acid or other to it prior to filtering also. May react with the ammonia compound and precipitate as a salt? Just me thinking out loud.

Hi Just Me. Thanks."

good morning mtnwalker2,
i agree 100%. dilute before filtering. i didn't pick up on that.buck36 you have to dilute to 50% or lower for the carbon to be effective.good sliding rock weather. it is getting a bit warm in texas.

Some days, it's not even worth chewing through the restraints.
