Many people buying dishwashers often overlook rinse aid, thinking it's unnecessary. However, this is what makes a big difference between "dry, sparkling clean" and "streaky" dishes. Let's find out.
What is Rinse Aid?
Rinse aid is a liquid added to a dedicated dispenser in the dishwasher, automatically dispensed during the final rinse cycle. It reduces the surface tension of water, helping water slide off dishes instead of forming droplets.
Why do dishes need rinse aid?
When water drains quickly, dishes dry faster and leave no streaks — especially noticeable on glass and plastic items (which take longer to dry). Without rinse aid, glassware can become cloudy and have water spots after each wash.
When is it truly necessary?
- You have many glass items or plastics that tend to retain water.
- You live in an area with hard water (very common in Vietnam).
- You want dishes to dry immediately, ready to use without wiping.
How much to use, is it expensive?
It's very economical: one bottle of Largo 1L rinse aid lasts for 200+ washes. You just need to fill the rinse aid dispenser and adjust the dispensing level on your machine, and you're set for a whole month.
👉 For dishes that are both clean and sparkling, use the complete set of dishwasher tablets + salt + rinse aid. See the economical combo genuine German products at sieutietkiem.com.
