Carpet cleaning
Next, a pressurized manual or automatic cleaning tool known as a wand passes over the surface to rinse out all pre-conditioner, residue, and particulates.
These systems are mostly "very low moisture" (VLM) systems, relying on dry compounds complemented by application cleaning solutions, and are growing significantly in market share due in part to their very rapid drying time, a significant factor for 24-hour commercial installations.
Heavily soiled areas require the application of manual spotting, pretreatments, preconditioners, and/or "traffic-lane cleaners", (commonly sprayed onto carpet prior to the primary use of the dry-cleaning system) which are detergents or emulsifiers which break the binding of different soils to carpet fibers over a short period of time.
[citation needed] A 98% biodegradable or other,[2] slightly moist absorbent cleaning compound may be spread evenly over carpet and brushed or scrubbed in.
[3] In the conventional cleaning process surfactant molecules attach themselves to oily soil particles, suspending them (emulsification) so that they can be easily rinsed away.
drytime), after cleaning, these encapsulators bind the detergent molecules and residual soils in a brittle, crystalline structure.
In addition to binding the detergent and soil residues the encapsulation chemistry coats the clean fibre with the same brittle film.
Products which also employ fluorochemical technology, display dramatically extended anti re-soiling time periods.
After a cleaning product is deposited onto the surface as mist, a round buffer or "bonnet" scrubs the mixture with a rotating motion.
This industry machine resembles a floor buffer, with an absorbent spin or oscillating pad that attracts soil and is rinsed or replaced repeatedly.
An overly wet bonnet also deposits residues that attract soils when they are dry, creating the need to clean more often.
Normally, the spin-bonnet method may not be as capable of sanitizing carpet fibers due to the lack of hot water, for this a special thermo machine is needed, here the buffing machine is equipped with a heating, to heat up the bonnet, but a post-cleaning application of an antimicrobial agent is used to make up for this.
This method is typically used to remove grease from the surface; some foams have color brighteners, protectants and anti-soiling agents.
This ensures high cleaning performance, extracting the dirt from the carpet to a depth of half an inch.
Vacuum washing has long been in use in Europe, mostly in larger train and bus companies, schools, and historic preservation.
The system works on all surfaces which are water resistant (carpet, upholstered furniture, wooden floors, stone, plastics).
Tea leaves and cut grass were formerly common for floor cleaning, to collect dust from carpets, albeit with risks of stains.
Ink was removed with lemon or with oxalic acid and hartshorn; oil with white bread or with pipe clay; grease fats with turpentine; ox gall and naphtha were also general cleaners.
These may be removed by professional cleaners or deep cleaning rental machines with heat-transfer stain-reducing chemicals, but carry risks of burning the carpet.
Stain removal products can be combined with anti-allergen treatments to kill house dust mites.
