Awesome, thanks guys. So I'll be on the lookout for shellite, or white spirits. At least they show up in search on the Bunnings website, and don't suggest I want to buy a 'Samantha'.

Shellite sounds promising from the description: https://www.bunnings.com.au/diggers-...llite_p1563463

White spirit also sounds good for cleaning grease, etc: https://www.bunnings.com.au/diggers-...pirit_p1563471

From reading the data sheets, looks like shellite will evaporate at much lower temperature, so will disappear quicker. It's also specifically mentioned as something to clean surfaces before painting. White spirits looks to be more of a general cleaner, can be used on carpets, etc, but will also get the job done in the shed I'd say.
