A Chemical Journey

Follow this timeline to learn how a Maintex cleaning chemical goes from raw materials to finished product.

Compounding
Expert compounders measure and mix raw materials in large vats. Some ingredients are measured in thousand pound increments. Others, like dyes and perfumes, may require only a few drops.
1
Quality Control - Round 1
Samples are tested for a variety of factors depending on the type of chemical. Common tests include: viscosity, pH, solids content, and visual inspection for color and clarity.
2
Filling
Pumpers are responsible for transporting liquids between production areas. Machine operators oversee filling lines, assisted by material handlers.
3
Quality Control - Round 2
Another sample is taken at the end of the filling line to detect any impurities or contaminants in the finished product.
4
Packaging and Storage
Product is packaged in cases, stacked on pallets, and shrink-wrapped for secure storage or transportation.
5
Shipment
When an order comes in, material is picked, palletized, and loaded for next-day delivery.
