I recently bought a 20 litre tub of molasses, dirt cheap from the rural hardware store.

Had a go at the process . I have to report that it works very well . I used a 44 gallon drum. A Morris drive shaft and gear box lid ... covered in rust . I used a strong mix .. around 5 parts water to 1 part molasses. Maybe the Summer heat has helped the process along , only took 5 days .

I've tried the electrolisis many times..in my opinion, it's more fiddly and not as effective as molasses.

A plus for molasses is you can leave it unattended . The electrolosis method always needs to be checked on , a possible fire hazard with fumes and electrical equipment overheating .
