When it is time to move out of a rental property, tenants want to recover as much as possible from cleaning deposits. The tenant responsible for the dirt and grime evident in the this image carefully read his rental agreement and found that it specified not just professional cleaning, but professional steam cleaning as the required cleaning method.
Professional deep cleaning sanitizes carpets, removes impressions from furniture, and extracts unsightly dirt and grime. You can see for yourself the dramatic difference on the left-hand side of the image where the carpet had been cleaned.
