Why does a commercial restaurant dishwasher require both detergent and a rinsing liquid? Find the answer here. Learn the function of dishwasher cleaner and rinse aid: how the cleaner destroys stubborn grease, while the rinse aid accelerates drying and prevents dull water spots on glasses. Discover why they are an inseparable system that becomes much more efficient with Niitaka’s Japan Quality automatic dispenser technology.
Investing in a commercial dishwasher for your restaurant or hotel is a huge step. However, many operations managers are surprised to learn that these machines require two different types of chemicals to operate. If you are confused, it is crucial to understand the function of dishwasher cleaner and rinse aid to ensure your tableware is truly hygienic. Is soap or detergent alone really not enough?
To answer this, we must understand that commercial-grade dishwashing works in a matter of minutes, not hours. Let’s break down how these two chemicals work together as an inseparable team to maintain your commercial kitchen’s hygiene standards.

1. Dishwasher Cleaner: The Grease “Fighter”

The first stage of the machine’s cycle is the wash cycle. This is where the Dishwasher Cleaner takes the lead.
Unlike manual dishwashing soap which produces a lot of suds, concentrated liquid detergents for commercial machines are designed to be low-foam but have a very strong alkaline pH level. Its main job is to break down tough food stains, spices, and animal fats in under two minutes. Without a heavy-duty detergent, your plates will remain greasy even if washed with high-temperature water.
2. Rinse Aid: The Perfect “Finisher”

Once the plates are clean from dirt, the machine enters the rinse cycle. This is the crucial moment where the Rinse Aid is injected.
If you only use detergent, the rinse water will form large droplets on the surface of the plates or glasses. As these droplets dry, they leave dull white marks known as water spots (mineral residue from the water). Rinse Aid works by lowering the surface tension of the water, preventing droplets from forming and creating a “sheeting action” where water just slides off.
The result? The drying process becomes significantly faster, and your wine glasses or ceramic plates come out of the machine sparkling clean, ready to be served directly to the guests’ table without the need for manual wiping.
3. Why Must Both Be Used Together?
Just like shampoo and conditioner, both have different functions but perfectly complement each other.
- If you only use Detergent: Your tableware will be free from grease, but will come out soaking wet and covered in water spots. Your staff will waste time wiping them one by one, which actually increases the risk of transferring bacteria from the wiping cloth (cross-contamination).
- If you only use Rinse Aid: The glasses and plates will dry quickly, but food stains and grease will still cling to the surface.
