Occasionally, we get asked by customers if the food-grade hoses we supply are ready for production usage right out of the box. The answer to this question is a resounding “no”. It is imperative to the safety of your manufacturing process lines to clean any products you receive before they come in contact with food, beverages, or pharmaceutical products.
Cleaning before first use
The food-grade hoses offered by Sanitary Fittings may arrive with a slight odor of their own, which is unavoidable from the manufacturing process but can be eliminated by proper cleaning.
We recommend the following procedures before the first use of your new hose:
- Fill the hose with hot water
- Store the water in the hose for at least 10 hours
- Empty the hose
