Record every mixing batch, its pH and viscosity, and the bottles filled from it.

Cleaning products are simple to describe and fussy to repeat. A floor cleaner that comes out thin one week and thick the next draws returns from every shop that stocks it. The cause is usually a water adjustment or a perfume dose that nobody wrote down. Returns hurt.

Cleaning product manufacturer software keeps the formula, the batch card and the filling record in one chain. The blending crew, the laboratory, the store and the filling line all read from the same batch number, so a question about one tank has one answer. Simple. Tell us which tank gives you the most trouble.

Raw materials arrive in drums, carboys and bags. They include surfactants, acids, alkalis, solvents, thickeners, colours, preservatives and perfumes. The store books each lot by weight and expiry. A batch card lists every ingredient with its quantity per tank, the order of addition and the mixing time, so the operator never works from memory. The blending operator weighs, adds and stirs for the set mixing time. The laboratory then checks pH, viscosity, density and appearance on a drawn sample before the tank is released to filling.

On the filling line, bottles are rinsed, filled, capped, coded and labelled, with the date and batch code printed by an inkjet that the operator checks at every start. Cartons are counted. Powders are blended in ribbon mixers and packed in pouches or bags by weight. Samples are retained. Each batch leaves one behind, for a stated period. Finished stock goes out to distributors, institutional buyers, hospitals, hotels and retail chains, each delivery note carrying the batch code so that the next complaint can be answered in minutes.
