Note: D-5671NS has been discontinued as it contains 3M HFE material which 3M has decided to stop manufacturing.  Customers should consider stockpiling D-5671NS while it is still available.  Sur-Prep® 123 has already been qualified as a replacement for oxygen system cleaning and general-purpose cleaning and can be purchased in bulk and aerosol formats.  If it is not necessary to use a non-flammable cleaner for general-purpose cleaning and the cleaning of oxygen systems, then the alternative product to use is Sur-Prep® 5677.  Sur-Prep® 5677 is available for purchase in bulk and aerosol formats.
