Carpet cleaning solutions are alkaline and the higher the alkalinity the stronger the cleaning solution. Alkalinity though can cause problems with carpets such as browning/yellowing or colour run. High alkalinity can also cause cleaning solution to not be rinsed fully from the carpet leaving residue behind which attracts dirt causing the carpet to re-soil quickly. Normal carpet cleaning alkaline would be between 8-10 with heavy soiling such as restaurants using higher strength solutions around 11-12.

Browning / yellowing:
This occurs when the back of a carpet gets wet during the cleaning process. Certain backings of carpets like jute contain cellulose which when wet release and wick browning up to the surface.

Dirtbusters acidic rinse is perfect for this task.
Blood on carpets can be very hard to remove in one attempt as the blood is so concentrated any residue left in the carpet will wick to the surface during drying.

The stain should then be rinsed with an extraction machine with warm water. Once dry a repeat of the cleaning process can be performed to remove the remaining stain. Rust remover can also help remove old blood stains in carpets.
