What formulation and concentration should I choose for rinsing liquid?
The first thing to check, especially in the case of professional dishwashers, is the water hardness. This hardness is measured in degrees TH.
Therefore, you should first check the hardness of the water that supplies your dishwasher.
A water softener will significantly reduce water hardness and prevent limescale stains and deposits on your dishes. Furthermore, limescale builds up more quickly at higher temperatures in a dishwasher.
The presence of softened water guarantees better results and lower product consumption.
If you do not have softened water, you will need to pay attention to the range of use of the rinse aid and opt for a product designed for hard water or all water types.
Foaming phenomenon linked to over-concentration of rinse water?
Sometimes foam appears when the dishwasher comes out, especially in the dispenser drawer.
This foam can be the result of using too much liquid rinse aid, but be careful not to automatically blame the product.
Indeed, in most cases, if pre-washing of dishes is done manually with a shower head or in a bath with a manual dishwashing product, it is the latter which, in the event of poor rinsing, can generate this foam.
A manual dishwashing product generates a lot of foam , and this poor rinsing, leaving traces of product, will have a multiplied effect in the dishwasher.
Is the rinse aid the only guarantee of the result?
In all cases, the rinse aid, just like the washing product, is only one element of the result.
A poorly maintained dishwasher with dirty rinse arms, clogged rinse nozzles reducing pressure, an unsuitable water temperature, etc., are all parameters that will be as important as, or even more important than, the product itself.
In conclusion, the product is certainly important but will never guarantee a result on its own, just as it will never be the sole cause of a bad result.
Why are my dishes coming out of the dishwasher white and dull?
No, it 's not necessarily the rinse aid or even the detergent. First, check the water hardness (TH) of your wash water (before adding any products that sequester limescale). If your TH is above 8, or even 15 or higher, your water is too hard , and combined with the water temperature, this hardness deposits on your dishes . This forms a film that will make proper washing increasingly difficult.
Solution: Check your water softener settings and then descale your dishes and dishwasher. Also, remember to check the salt level in your water softener !
I have a lot of foam in my dishwasher's detergent drawer?
Two possibilities: either you have too high a dosage of rinse aid , or you pre-wash with a hand dishwashing product that is not rinsed enough and it is the "remnants" and traces of surfactant from the product which, once in the tub, create this foam.
Solution: reduce the rinsing dosage and check that the dishes are properly rinsed during the pre-wash by hand.
