Degreasing compositions that may be used, for example, to degrease substrates such as contaminated surfaces of automobile engines are disclosed. The degreasing compositions comprise a builder, an amphoteric surfactant, and an alkoxylated acetylenic diol having the structure of formula (I) or (II): ##STR00001## where: R.sub.1 and R.sub.4 are, independently, alkyl radicals containing from 3 to 10 carbon atoms; R.sub.2 and R.sub.3 are, independently, selected from the group consisting of methyl and ethyl; and (x+y)=2 to 50; ##STR00002## where: r and t are each, independently, 1 or 2; (n+m)=1 to 30; and (p+q)=1 to 30. Certain embodiments of the degreasing composition are non-caustic, low VOC and may be low phosphate or phosphate-free.
