We produce more than 2000 different products with each their own soil/substrate combination.
Our product development is aimed that each product can be kept for at least one year after production. But there are a few exceptions. This is of course dependent on the storage conditions, but also for different product ranges, different rules apply.
Some products, according to data, can be stored for more than 10 years. CFT always strives to deliver high quality products and we strive to prevent waste, thus save costs, therefore we work with a strict QC (Quality Control) system.
We check all our standardized testmaterials after batch production and re-check all our products if they are still in our inventory after 6 months. When they pass CFT’s strict Quality Control the products are valid for another year. This makes sure that our products are at least usable for 6 months after you receive them. When you still have an older product batch in stock, please feel free to contact us for a re-check in the meantime.
For Circular stains we run wash tests (Wet QC) during the development of a stain and when the recipe of the staining material changes. If the latter is not the case, we only run Dry QC. That means that there is no QC data per batch to compare to. Since most of these Circular Stains are made to order, we do not have a large stock. Stains will be valid (if properly stored) for 1 year after production. If they are close to 1 year in our inventory, they are discarded.
For Dishwash Monitors we do run a Wet QC for every produced batch. The storability rules are basically the same as for Standardized Testmaterials. When 6 months in our inventory we re-check the QC data, so that all our stock, when sold is at least valid for 6 months. Often longer.
