excuse my memory! what would, or could happen if you dont nuetralise with an acidic rinse on a single coloured carpet that has unstable dye (transfer during dye bleed test) and left in a high alkaline state?

Scott,

An unstable dye can dry patchy and be liable to crock-loss (eg. transfer onto cotton socks).

Also it is likely to be vagrant in the event of spillages, leaving a strong peripheral colour around a paler area.

I hate the whole concept of neutralisation

you've got one chemical on the carpet so you  'neutralise' it with another, which means you've now got 2 chemicals on the carpet.

instead of 'neutralising' how about 'removing'
