Bicchieri_lucenti2Both household and professional dishwashers are generally made to work with detergent and rinse-aid. Detergent is usually alkaline, it degreases and suspends soil in washing water; rinse-aid, acidic or neutral product characterized by the presence of antilime agents and drying increasers, enters during rinsing phase. The latter contains surfactants too, with the aim to spread rinsing water through glasses and cutlery surface, preventing lime incrustations.

Sometimes rinse-aid surfactants may leave a slightly bitter taste upon glasses; for this and other reasons (as suspicion about toxicity), for household use many people choose to substitute rinse-aid with wine vinegar. However, even if it is natural and non-toxic, it may be harmful for… dishwasher itself! Unlike other uses (surfaces cleaning, fabric softener) vinegar has the power to corrode stainless steel rinse-aid reservoir: while the spigot is plastic-made, usually backside is the stainless steel-made door of the machine itself. It may be unsettling to find that our dear, faithful dishwasher ends its life with a big hole, hidden into its door until the water leakage becomes irreversible…

If you would like to avoid using rinse-aid and – at the same time – to save your dishwasher too, the best thing is to use Citric Acid code ACIT or else products containing citric acid but not surfactants, as Descaler code AE: citric acid does not corrode stainless steel. Anyway, Bensos’ rinse-aids (Household Rinse Aid code B and Extra Rinse-aid code BX) does not contain any toxics, so users may choose among products with no concerns.
