Washing crockery, cutlery, utensils, and other cooking equipment between uses removes food scraps, residues and grease. All of these are potential environments for microorganisms to grow and multiply. Food scraps also attract pests which bring further pathogens into food preparation areas.
Many commercial and institutional settings have dishwashing machines to speed and automate the dishwashing process. Dishwashing can also be done by hand.
I&I detergents are available in many different formulations to suit different applications, including: dishwasher or hand washing; general purpose dishwashing, heavy duty dishwashing, or washing specific materials such as glass or metal; and, soaking cutlery. Additionally, some detergents are designed for use in soft water or hard water.
Dishwashing detergents are available as powders, liquids and tablets. Liquids are usually produced as concentrates or superconcentrates and need to be diluted with water before use. Formulation of detergents in concentrated form has important environmental benefits: less chemical ingredients and water are used in manufacturing, and less packaging and transport of the finished product is required. These reductions translate to savings in resources, energy and greenhouse gas emissions.
There are also I&I rinse aids designed to prevent residue on glassware, promote quick drying or a streak-free finish.
I&I descalers are designed to remove mineral build-up (e.g. from hard water) in dishwashers, bain-maries and urns.
All of these products play an important role in keeping commercial food preparation and service clean and hygienic, and for helping to make dining out the special experience it should be.
