good evening all ive been out today to price up two jobs got the first one ,went on to the second give them a price but then they started asking about protectors this is the first time i have had a customer ask me about this product. The carpet is three years old and never been cleaned the customer was unsure whether they had Protector put on when fitted. I said i would look into this and get back to them as they were happy with the price i quoted what protector should i be looking for , do you apply via a spray , do you apply once you have extracted or do you apply when carpet is total dry (sorry for the long winded post ) any helpful advice would be great many thanks Gavin
