G'day Terry,

Thanks for the link about molasses - it is great stuff. I am not sure of what state or country your "on the river flats in a poor part of town" is? Your description from your signature line. If you look at mine it says Bundaberg - Queensland Bundaberg is one of the main sugar cane growing areas. I have sugar cane across the road in front of my house and about 50 metres from my back fence

There are some alloys that get eaten by the mix though. I have to dig around and re familiarise myself with which ones.

P.S. With the magic of the Interwebby ... Accessed November 13, 2016 from, http://www.mtfca.com/cgi-bin/discus/...slowpoke-users Molasses will start "moon crater" pitting cast iron if left in too long. Not a problem really on brackets, but engine blocks will pit on the machined surfaces.

From the same forum/thread - http://www.mtfca.com/cgi-bin/discus/...=matthew-users Be warned I let a Cylinder Head set in this solution for over 2 weeks and it started to eat the Cast Iron. I should have pulled this no more than 3 days.

From another forum...The Australian Land Rover Owner's Accessed November 13, 2016 from, http://www.aulro.com/afvb/projects-t...ml#post1356303 DON'T place Any non-Ferris metals in molasses as you wont get it back. It converts alloy and brass to a horrible sandy mess in the bottom of the tub.

Got it - this was the old post I was looking for ... Accessed November 13, 2016 from, http://www.aulro.com/afvb/projects-t...ml#post1418961 A 1:4 (molasses:water) will eat white metals like aluminium, lead and zinc. Put a seized block into a bath and in a couple of weeks you'll have a clean block with the rings sitting in the hollow bores. The author of the message used the properties of molasses to their favour ...

New pistons are easier to find than a 1948 side plate Landy block.

Hello Diana
