Fabric Cleaner & Spotter works by loosening the dirt & stain molecules that latch onto fibres. This is done by spraying the Fabric Cleaner onto the dirty surface & 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.
