I worked Tuesday night, grabbed a few hours sleep got up and went to a rental.
Luckily it had only two rooms with carpet as I felt like the living dead.
I used Powerburst and FF rinse and they came up pretty well.
Today I had a minger so went to get the Ultrapac Renovate from the van.
It was not in its usual place but where I usually keep the FF rinse.
It then dawned on me that in my Knackered state the previous day I had put ultrapac in the solution tank instead of FF rinse.

I even thought as I poured it in that it looked a different colour but my brain did not register what I had done.
I have told the Agent that I need to go back and vac the fluff up rather than tell the truth.
