Fabric Cleaner & Spotter works by loosening the dirt and stain molecules that latch onto fibres. This is done by spraying the Fabric Cleaner onto the dirty surface and allowing it to dwell. The molecules in the product vibrate against the dirt particles loosening them from the fibres they have stained, allowing them to be easily wiped up with a piece of Terry Towel Cloth. This unique cleaning action makes the product totally safe to use without causing any damage to the surface it is applied to; no need to over rub or scrub a surface, just allow to dwell.
