Sasha4, i expect TonyG will give the same answer as this, but you never know.

Milk is the worse of all typical spillages and once allowed to decompose enough to start smelling as bad as you say then the only cure is new carpets/seats/underlay even anti vibration pads, whatever material that got soaked, the smell won't go for many years if ever.

The only way to deal with spilt milk is to immediately remove every affected item and wash throughly before it dries.

One of my ex (Mr Perfect) colleagues spilt a cup of coffee in the slide out tray in my lorry, he said he mopped it up as best but...

After about 2 months the most dreadfull smell was present which i couldn't explain, after several months of almost throwing up i eventually traced it, dismantled the tray and in doing so removed the rubber fitted mat...all became apparent as the smell hit me, there was a long dried stain approximately 2" in diameter of the tiny amount of left over milk residue trapped under the rubber mat.

The hard plastic tray cleaned up OK, but the rubber mat had absorbed the odour, i steam cleaned it, bleached it, put it in the dishwasher, scrubbed it rubbed it wire brushed it, nothing at all reduced the power of that foul smell...eventually had to throw it out.

Can't agree GB. A work colleague had his young child throw up shortly after a drink of milk.

Well, it was milk wasn't it, you know milk as in milk that the young child had just consumed?

Strewth, that BT bloke he'd argue with a drunk horse..;) as in get off yor horse and drink yor milk.!!

We've had a few instances of milk spilt in cars. One was from a leaking bottle in the boot, another from a flask of coffee. With three children, the last of whom was travel sick with a frequency and intensity that had to witnessed to be believed, all of our cars have been subjected to vomit.

When we had an MPV I could remove the seats and wash them (in one spectacular instance I had to literally hose the seats down). I've not tried the vinegar method but I did have success using bicarbonate of soda once the seats/carpet are dry. Spread it onto the affected area and leave in place for as long as possible then hoover. On one occasion I needed to repeat the process over several days but it always worked!

Enjoy...
