We never get daytime temparatures below 30c (86f) here, so I couldn't comment on whether effectiveness is reduced at lower ambient temps.

Then unfortunately the product you're using isn't that great of an engine degreaser. Most well known engine degreasers, will even go to the extent of asking you within their instructions to warm up the vehicle. The reason they would like your engine warm to the touch, is that it actually helps loosen the build up and helps in preventing the engine degreaser from evaporating too quickly.
