How do I use Dishwashing Tabs for best results?Updated 3 hours ago

No. Each Koh Dishwashing Tab is pre-measured for one full wash and balanced for the cycle. Cutting it in half means half the dose for a full load: spotting on glass, stains that don't shift, and risk of gritty residue or undissolved detergent clogging the dispenser. Don't unwrap the PVA film either, it's water-soluble and designed to dissolve at the right moment in the cycle. The film also keeps direct contact with concentrated detergent off your hands.

Placement depends on the cycle. For normal, auto, and eco cycles, drop the tab straight into the detergent dispenser and close the flap, the dispenser opens mid-wash to release detergent at the right moment. For quick or 30-minute programs, the cycle may end before the dispenser opens or before the tab fully dissolves, so skip the dispenser and lay the tab flat on the tub floor, centred under the lower spray arm. In drawer and compact dishwashers, follow the same rule: dispenser for standard, tub floor for quick.

Loading matters more than most people realise. Spray arms need clear paths to every dish: no nesting bowls inside bowls, no plates packed too tight for water to flow between them, no tall items blocking the top arm. Scrape off large food scraps but don't pre-rinse, place bowls and cups facing down on the top rack, stand plates between the tines on the bottom rack, and face dirty surfaces toward the centre where the spray hits hardest.

If glassware comes out cloudy or spotted, it's usually hard water, not the tab. Try these in order: top up the rinse-aid reservoir (rinse aid helps water sheet off glass cleanly in hard-water areas), run a hotter cycle (eco cycles can struggle in very hard water), move the tab to the tub floor if you're on a quick or eco cycle, and check the salt reservoir (refill with dishwasher salt). Dull and chalky all over points to hard water needing ongoing rinse aid plus salt. Just a few spots usually means a loading issue.

Keep the pouch sealed when not in use. Store in a cool, dry place away from direct sunlight and away from the sink or dishwasher (steam and splashes start the PVA film dissolving). Handle with dry hands only. Unopened, Koh Dishwashing Tabs are shelf-stable for at least 12 months.
