I use shellite if the glue is still soft and easily removed. For stubborn residue, I use Goof Off - also available at Bunnings. Be VERY careful with this product. It's biggest advantage is that it easily removes residue, but it's disadvantage is that the fumes are really bad, and you need to be careful as it can lift paint if you let it settle for too long.
Shellite (White Spirits) is also called Naptha in the USA.
