Engine Cleaning with Degreaser: Is It Safe?
Because degreaser easily dissolves burnt-on grease in ovens and on hobs, people are tempted to try it on other greasy surfaces at home and at work. But as a strongly alkaline product, it is not suitable for every surface. This guide explains whether degreaser can be used on engines, glass, sofas, air fryers and wheel rims, and where it should be used.
Can you clean an engine with degreaser?
Not recommended. Kitchen degreasers such as START Degreaser are strongly alkaline products made for burnt-on grease in ovens and on hobs; according to the safety data sheet, the pH is 12. Car engines contain aluminium parts, painted surfaces, cables and electrical connections; a strong alkali can corrode and dull aluminium and damage electrical components. For engine cleaning, use the products recommended by the vehicle manufacturer or leave the job to a car service.
Can you clean glass with degreaser?
It is used on burnt-on grease on the oven door glass: how to clean oven glass. On windows, mirrors and car glass, however, it is not recommended; alkaline residue can leave marks on the glass and damage frames, seals and painted surfaces. For this glass, use glass cleaner.
