Streaks in carpet

Had a customer in January this year phoned me and asked if i could call and have a look at her carpet. On arrival she informed me that her carpet was cleaned two weeks ago and when they had finished she could see streaks in the carpet? so she phoned them and the reply was "the carpets were fine when we left". Any way done a burns test and the construction of the fibre was wool then done a ph test show a high degree of alkaline residue left in the carpet. Fired up the truckmount and rinsed with Hydramaster rinse out and bingo as good as new which lead to four referrals.

Good job! But you could have sprayed fabric softner and raked it also.

Are we talking cellulostic browing or streaks left by the wand?

yea good question are you talking about brown streaks? For me I try to lower the water pressure and only do a clean going up on a stroke and then dry coming back. It always happens in corners or under furniture or new carpet. Not really in traffic patterns

Lower your pressure, use less prespray, and use a good rinse. Jimmy Crawford, good job, you sound like you're on the ball.

well what you guys said about the streaks is exactly vorrect. Even I was following the same way in order to remove streks form the carpets. I don't know how to remove the hard streaks from the carpets.
