So does that mean using the Acetone has completed the job in less washes than it would normally take Mark ?

Yes, I normally do 3 or 4 washes.

 Wicked, that's a good result for starters.  My batch is made, when I get to wash it I will be adding the Acetone with the first wash.

How much are you going to add ?
I used 20ml in 180L of bio.

I hope your results confirm my findings.

Do you do titrated acid washing, if you do I wouldn't add the acetone to the first wash as we have no idea what the outcome will be,
maybe Carrington can enlighten us on this.

My last one was... but I have demethed this batch as I believe the Methanol interferes with washing too.  Sooo..  I will be talking to Paul first. And using an amount along your lines. Cheers Mark.

I've believe that too!  I'm sure that when I've demethed (bit fiddly without a venturi - pulling in air on the suction side of the pump), washing has been easier.

I'd be interested in testing meth % on each wash, but as I've mentioned previously I've a theory that meth ppms or % reduces over successive washes until it reaches a threshold where soaps release at higher volumes.  I could be wrong, but everything that I've seen with years of water washing suggest this.

Hi Mark,
    no sorry I have not had a chance to catch up with Paul yet, I did a 50/50 with bio from the bottom and to be honest it was not that white so I have high hopes once I get to neutralise it and give it a wash.

As this batch will have had a fair settling time I will keep a sample before washing and one after to do some side by side cold testing which may be interesting too.

Side by side testing would be great.

Once I some more IPA I'll do the same.

I rather suspect, Steve, that mark has run out of IPA for performing titrated soap tests. A key ingredient and test for for what you're trying to acheive.

I've got a batch from a week and a half back that seems to be settling rather slowly, so I've taken a 75ml sample and added 0.5ml Acetone (0.66%)

I'll compare this for soap with the rest of the batch later this week.

I'm also about to make a new batch tomorrow, I was going to take 2x 500ml samples in the same jars, one with and one without acetone to compare settling of those.  What percentage do you think I should try?

Tony, I added 20ml to 180L of bio for my washing,
that works out at around 0.1ml per liter,
this could be a starting point for you.

That's not much at all.  I'll try 0.1ml in each 500ml sample then.

The one that wasn't settling is showing some faint signs of soap at the bottom today.

I have had a demethed KoH  180 litre batch settling in my reactor for the last week or so, once a day I have been dropping the glyc, all nice and dark.
  Yesterday only a drip came out so I put in 200ml of Acetone and mixed for 20 minutes at ambient temp. Today I dropped 350ml of dark glyc ! So it has released more from the Bio. I will see what drops tomorrow and then take a sample for a 50/50 test.

  I may end up not washing this batch and the next batch will get the Acetone after demething and probably once it has cooled a bit.
