Actually you are right it is a cream, like in Citrus Gel. I use it all the time it is brilliant and I wouldn't do without it. Those true gels, I just can't get on with. I had two call backs in a week when I purchased some to try, after it left white residue even after many wand passes. They were the only call backs on carpets that I have had in at least the last last 15 years.
