Can I use plain water in Spray Mop?Updated 17 hours ago
TL;DR: Only fill Spray Mop with Universal Cleaner, never dilute. Plain cold water works only for oiled or waxed timber floors. Never use other cleaning products or add citrus essential oils, as they degrade the plastic. Empty and rinse the bottle between uses to prevent odour or build-up.
