I'm posting here for visibility and hopefully some quick replies.
DS2 has D&V.
A few nights ago he vomited spaghetti bolognaise all over his bedroom carpet. It was late at night, so we cleaned it up as best we could and put him back to bed. The carpet has quite a deep pile and it is really starting to smell - you can smell it in the porch when you enter the house.
I've tried cleaning it by hand with Fairy Liquid and a scrubbing brush.
With Vax platinum twice.

But the smell persists.
I've read some other threads which suggest an enzyme based cleaner is required. That makes sense and I don't think the Vax liquid is enzyme based because it is 'certified wool safe'. Our carpets are polypropylene, so that isn't a problem.
Would I be making a mistake by adding a dose of Sainsbury's Bio Super Concentrated Laundry Liquid to the Vax's water tank?

It says "Machine washing dose = 25ml", so I was thinking of adding that amount to the tank. The machine's water tank is only 4 litres, so that might be a bit strong, but the smell is really bad and the enzymes need to chug down that puke.
Is there any risk to this - e.g. if the enzymes come into contact with wooden floor joists are they going to munch on the wood in some way and weaken the floor?
