Can I use Dishwashing Liquid in the dishwasher?Updated 10 days ago

TL;DR: No. Dishwashing Liquid is designed for hand washing only (sink-soak or dish wand). It's a high-foam formula and dishwashers need a low-foam detergent. Using hand dish liquid in a dishwasher causes foam overflow, poor cleaning, and possible machine damage. For dishwashers, use Dishwashing Tabs.

Can I use Dishwashing Liquid in the dishwasher?

No. Koh Dishwashing Liquid is designed for hand washing only (sink-soak method or dish wand). It's a high-foam formula. Dishwashers require low-foam detergents because the spray jets aerate the liquid and create runaway suds that overflow the machine, leak onto the floor, and prevent the cycle from cleaning properly. For machine dishwashing, use Koh Dishwashing Tabs, which are formulated specifically for dishwashers with the low-foam profile machines require. Septic safe, GECA eco-certified, made in Australia.

⚠ Hand wash only

Dishwashing Liquid is designed for sink-soak or dish wand use. It's a high-foam formula. Dishwashers spray water at pressure, which aerates hand dish liquid into runaway suds that overflow the machine, leak onto the floor, and stop the cycle from cleaning properly.

What if I already did?

If hand dish liquid has gone into your dishwasher and the cycle has started, stop the cycle, open the door carefully, and clear out as much foam as possible with towels. Rinse out the detergent dispenser and the bottom of the tub. Run an empty rinse-only cycle to clear residual suds (you may need two or three short rinse cycles to fully clear the formula). Add a tablespoon of cooking oil or salt to the wash water if foam keeps reappearing, both reduce surface tension and help the suds collapse. Once the machine is foam-free, run a normal wash with Koh Dishwashing Tabs.

✓ Foam recovery, four steps

1

Stop the cycle. Open the door carefully and scoop out as much foam as you can with towels.

2

Clear residue. Rinse out the detergent dispenser and the bottom of the tub.

3

Run rinse-only cycles. Two or three short rinse cycles usually clear the formula. If foam keeps reappearing, add a tablespoon of cooking oil or salt, both reduce surface tension and help the suds collapse.

4

Run a normal wash. Once the machine is foam-free, load up and run a normal wash with Dishwashing Tabs.
