Carpet dry cleaning is a process where the carpet surface is pre-vacuumed and then treated with solvents to break down dirt within its fibres. Once this treatment takes place, special machinery uses cotton pads that spin around on top of your carpets removing stains or soil attached to the fibres. The main benefit is that your carpet is walked on dry immediately and only takes 1-2 hours to fully dry.
On the other hand, steam cleaning works by using special equipment which injects water into the carpet under high pressure and then removes it. This method is similar to a vacuum cleaner however, instead of using air to suck up debris, it uses hot water. Once the water has been extracted from the carpet, it takes all the built-up grime and dirt from the carpet with it. However, this method can take 6-12 hours for your carpet to fully dry.
