Just started in the industry and want a bit of advice.A mate of mine wants his heavily patterned carpet cleaning.Went to see carpet,did burn test(synth),checked backing(woven with same pattern as top of carpet),put small amount of water on(it went straight through).From all this determined its a BW.The carpet is well fitted apart from some shrinkage near the door.Told mate this would have to be secured before i attempt to clean it,as i know this type of carpet is prone to shrinkage.Carpet isnt minging so thought i would Pre-spray with Prochem Prespray Gold,and extract with Fab & Fib,then dry with turbo dryer.Does this sound OK?What psi should i extract with?Any other points?
