Storing Metalworking Fluids

Metalworking fluids are highly engineered products that require care and control. The individual components formulated into metalworking fluids provide a variety of different features such as bio-stability, corrosion protection and lubricity, along with emulsifiers and anti-foam. Combined, these elements provide a very finely balanced formula that, when stored and mixed correctly, allow customers to optimize their performance.   

Proper storage of metalworking fluids involves paying attention to the product’s manufacture date to ensure your inventory is being turned on a regular basis. Most soluble coolants can be stored for one year from the date of manufacture. Typically, the batch numbers and manufacture date can be found on the product label. This information can be used to make sure older product is being used first.

It is best practice to adhere to the recommended shelf life of your fluid as you may detect a loss in performance if the shelf life is exceeded.


Metalworking fluid storage tips:

  • Most metalworking fluids should be stored inside.
  • Fluids should be stored between 5 °C – 40 °C (41 °F – 100 °F).
  • Avoid freezing during transportation to and storage at your facility.
  • If fluid containers are stored outside, they should be covered to protect containers from the elements.
  • If exposed to rain, drums should be covered or stored on their sides minimizing the risk of water entering the drum through the bung holes.
  • Fluids should not be stored in direct sunlight.
  • Rotating fluid regularly helps safeguard the fluid and keeps it in excellent condition. Remember FIFO (First In, First Out).
  • Ensure labels are visible on all fluids.
  • Storage information can be found in Section 7 of the product’s Safety Data Sheet (SDS).

Many local states and municipalities have guidelines that need to be followed for spill containment of certain fluids. Check with your local authority to ensure you are following the latest regulations.

Proper storage of your metalworking fluid is just the first step in the development of a fluid management program. Talk to your Chem Arrow representative about developing a customized program that will improve performance and reduce your overall fluid related costs.
