On advice for new starters:
Shouldn't we rather say that when a carpet has the fetures of a belgium wilton, you should be very cautious.
Thin/Synthetic Pile
Natural Fibre Backing
Aren't these the features that lead to shrinkage when you use a bad cleaning method?
I may be wrong, but at the beginning I was paranoid of belgium wiltons - but now I don't even bother. If there is a chance of shrinkage on any carpet you have to proceed with caution.
