Can I cut Dishwashing Tablets?Updated 4 hours ago

Short answer: Keep each tablet whole. Cutting upsets the detergent balance. Use the dispenser for normal cycles; lay the whole tab on the tub floor for very short programs. This applies to compact to full-size dishwashers.


Why you shouldn’t cut tablets

  • The ingredients pre-measured for one wash.
  • Crumbing the tab can leave gritty residue and reduce cleaning power.
  • The clear dissolvable film keeps undiluted ingredients off your skin, cutting removes that protection.

Best placement by cycle

Cycle typeWhere to place the whole tab
Normal / AutoInside the detergent dispenser.
Quick / 30-minFlat on the tub floor, centred under the lower spray arm.
Eco (low-temp)Start with dispenser; if residue remains, try tub-floor placement.

Why the tablets are film-wrapped

The PVA film stops direct contact with concentrated ingredients, which can irritate sensitive skin before they’re diluted in the wash. It also keeps each tab intact until water activates it, no need to peel or unwrap.

Quick tips for spotless results

  1. Load dishes so spray arms can reach everything, no nesting bowls.
  2. Handle tablets with dry hands to avoid premature dissolving.
  3. Rinse aid might still be needed depending on your area's water hardness.
  4. Store the pouch sealed, in a cool, dry place.

If dishes still look cloudy, try a hotter program or move the tab placement before considering any dose changes.
