Rinse aid

Rinse aid is used to ensure that the load is dry, with a universal sheen and

free of filming, streaking or stains at the end of the wash program.

Depending on setting, between 2 and 6 ml rinse aid is used per wash.

Rinse aid ensures optimal wetting of the load and at the same time leads

to sheeting of the rinse water as it drains off. The better the water drains

off, the better the drying of the load and the less the tendency for marks to

remain on items. If rinse aid is not used, evaporation residues (dried on

water drops) remain on the load because the softened water contains

dissolved salt.

Note

Only rinse aid designed specifically for dishwashers may be used.

Normal liquid detergent must not be used.

Domestic vinegar with max. 5% acidic content or up to a 50% solution

of citric acid can be used as alternatives but drying and rinsing results

will be greatly impaired compared to those experienced with rinse aid.

Vinegar with a higher acidic content (e.g. concentrated vinegar) must

not be used as it may cause damage to the machine.

Chemical composition / Function of various components

1. Wetting agent (non-ionic tensides):

2. To reduce the surface tension of the water. The load is

thoroughly wetted and foam-free washing is ensured.

3. Solubilizer (alcohol, xylolsulphonate or cumolsulphonate):

To ensure stability of the rinse aid by preventing the

components separating out.

4. Organic acids (citric acid, fruit vinegar):

To remove the residual hardness elements of the water and

prevent deposits and possible transfer of alkaline residues in

the suds. The storage and temperature stability of the rinse

aid is increased and mold development is prevented.

5. Preservatives:

To prevent mold development.

6. Fresheners:

To give a pleasant odor.
