Title: First ever water wash
Post by: Tony on October 19, 2012, 07:54:42 AM

That batch that wouldn't settle still hasn't... so I've finally relented and it's bubble washing in the shed at the moment.

A little nervous that it's formed a big orange gloop but we'll see!

Edit:  Just switched it off, I understand with bubble washing 8 hours is plenty enough and it's had 10.  So it can settle until this evening.

Did you warm it first Tony? imperative for the first wash really I have found, you can still imulsify the bio even with bubbling.

No just cold water.  It only has a very small amount of soap left in it after settling for so long.

If it forms an emulsion can I add salt to the water to fix it?

Came back from work to find it nicely split, doing a second wash now.  At least I can claim I've done water washing now.  I might even get an honorary mention in the water washers corner of BBB 2013.

Tony, you're only aloud in the water washers corner if you do acid titration pump washes, it's the new black you know.

We are easily recognisable from the acid burns  :)
