Milky diesel - diesel bug?

[thinwater]

Neils issue suggests that whether this is truly emulsified or not and was previously clear :
The tank already had contaminants,possibly water in it that were not cleared during 'polishing' and these were entrained by use of a high speed pump during the polishing .
Or contaminants,water or detergent were used in the tank or lines and not cleared before refilling.
Or water was introduced in a fuel top up.
But it doesn't sound easy to emulsify - is it possible that an injector can blow back ,probably not ?
I see that Wynns make an inexpensive water remover - £ 10 for their ' DRY FUEL' product that treats 60 litres of diesel or petrol,but I can't find any detailed application guidance.

An SDS is not full information but ...

• greater than 50% propanol. An alcohol that will absorb water
• 5-10% 2-butoxyethanol, AKA celusolve. A powerful co-solvent that used to be used in strong de greasers. Bad for many elastomers.
• 1-2.5% ethoxylated amine. Emulsifying surfactant.

Basically it uses polar solvents to emulsify and dissolve traces of water. Celusolve has been specifically identified by many engine manufacturers as a chemical they don't like seeing in fuel additives. Will it do any harm in a single use? No. But it may not do any actual good either. If the water is truly finely emulsified (it hasn't settled, so the answer is yes) then either way the water will pass without harm. Sump the bottom of the tank, use a separating filter, and burn it up by using the engine.
