irabionist Posted August 28, 2017 I kind of bought too much Caustic Soda from a chemical supplier in bulk as it was the only place around that had close to 100% and I don't need it all. Use it for soap or for essential oil extracts, maybe you have a real bad drain.... idk There's ~20kg available. $15/kg + what ever postage is, or pickup Northern-Western Suburbs of Melbourne or the whole 20kg for $100 (but you'd have to pick up) 4 Share this post Link to post Share on other sites
irabionist Posted September 22, 2017 Still quite a bit left, postage seems to be $15-20 to anywhere in Aus for 2-3kg Share this post Link to post Share on other sites
