Before & After shots of a house party gone wrong, basically I used the power of Carbonation with the assistance of a pre-spray, some agitation & dwell time. Even on white wool carpet stain removal can be achieved but keep in mind 'the longer you leave these sort of stains the harder it will be to achieve the desired result' Wool is a Natural fibre and not as responsive as your Nylon/Synthetics.

Chem-Dry's patented Carbonating Cleaner is applied using a low pressure applicator that applies millions of microscopic carbonated bubbles into your carpet, then with the power of carbonation lifting the dirt and grime to the surface to be extracted and swept away forever. This process leaves your carpet in a drier and cleaner state, more than steam cleaning accomplishes.
