For spot-cooling of electronic components during troubleshooting, dimethyl ether or tetrafluoroethane may be used.Knight KL, Brucker JB, Stoneman PD, Rubley MD. Muscle injury management with cryotherapy. Athl Ther Today. 2000;5(4):26–30.

Freeze sprays are also used to contract metal for assembly or disassembly of interference fit parts.{{Citation needed|date=October 2022}}

The extreme temperature can cause viscoelastic materials to change to glass phase. Thus it is useful for removing many types of pressure sensitive adhesives.{{cite patent|country=US|number=5798169|title=Self-containing tamper evident seal|pubdate=1998-08-25|assign1=Sealed Air Corp.|inventor1-last=Smith|inventor1-first=Christopher A.}}

In medical applications, spray cans containing dimethyl ether{{cite news | url = http://www.pharmacytimes.com/issue/pharmacy/2006/2006-07/2006-07-5674 | date = July 2006 | title = A Pharmacist's Guide to OTC Therapy: OTC Treatments for Warts | access-date = 2017-08-26 | archive-url = https://web.archive.org/web/20100617043246/http://www.pharmacytimes.com/issue/pharmacy/2006/2006-07/2006-07-5674 | archive-date = 2010-06-17 | url-status = dead }} or tetrafluoroethane may also be used to freeze and destroy tissue, for removal of warts and skin tags, or other uses in cryosurgery. Liquified petroleum gas including propane and butane is sometimes used. These all may also be used as a topical anesthetic, due to the numbing effect of cold, though there is risk of frostbite.

Cold sprays are sometimes used to carefully freeze and kill attached ticks, with successful application often resulting in the dead tick falling off.{{Cite web |date=January 2023 |title=Guidance Note for medical practitioners and hospitals - Prevention and management of tick bites in Australia |url=https://www.health.gov.au/sites/default/files/2023-01/prevention-and-management-of-tick-bites-in-australia.pdf}}

Chloroethane may be used as a topical pain reliever, and an alternative to ice pack therapy to reduce inflammation and swelling. Since its boiling point is well above the freezing point of water, there is less risk of freezing the skin, though it can still be dangerous if misused. It may be used to treat sports injuries, where it is sometimes known as ice spray or magic spray.{{Cite web |url=http://www.dw.com/en/magic-freeze-sprays-can-do-deep-damage/a-18520903 |title='Magic' freeze sprays can do deep damage |last=Widman |first=Miriam |date=June 16, 2015 |website=Deutsche Welle |access-date=August 26, 2017}}

Freeze sprays are also utilized in frozen section biopsies to rapidly cool or freeze small tissue samples at the microtome or cryostat.BBC Biochemical, "Histological Freezing Spray," S91 datasheet, March 2017. https://www.statlab.com/pdfs/sds/Histological_Freezing_Spray_Safety_Data_Sheet.pdf

Freeze spray has been shown useful for the field marking of animals; for example marking the tails of monkeys. Research is continuing to help control the application dosage and time to minimize permanent damage to the animals.{{Citation
