molasses

[fervens]

I found an interesting video while stuck in an infinite wikipedia/youtube loop after looking up info on acids. I know everyone here, myself included, swears by white vinegar for removing rust from their vintage axe head finds, but I think this warrants some looking into.

The guy mentions that rust would quickly form after rinsing. I did notice that he didn't neutralize the acid with baking soda which may help stop that. Anf a quick oil rub is always a good idea any way.

Just though I would share.

Thanks for the video. We used to use molasses when we were pouring exposed aggregate concrete. It stops the surface of the concrete from hardening. Spray it on diluted 4:1. After a couple hours just hose and broom it off and you got exposed aggregate. We'd buy the cheap gallons from the feed store.

I don't use vinegar, white or otherwise.

Let's clarify this:

Molasses 10:1 with?

That's a neat trick. Who knew.

Thanks for the thread, I didn't know about fermented molasses (and the resulting acetic acid) being used as a rust remover. I wonder if plain sugar water would work (in the same proportions), kinda like making your own vinegar.

I've used this trick before when making concrete pavers in a wooden frame "mold". Just used a paintbrush to soak the plywood with the molasses/water before filling it with concrete. The next morning, tip out the paver and hose off the top to get the exposed aggregate look (just like the ones you can buy, although you can customize the homemade pavers by laying in pieces of broken tiles, etc, to create some artwork before putting in the concrete). I've read that plain sugar water will also work for making exposed aggregate pavers.

Yes, plain sugar water works fine. Coca-cola will do the job, too. We've used it when we ran short of molasses water.

The feed store molasses has sugar lumps in it. We would mix it up in a 5 gallon bucket and then strain it through a pair of panty hose into our pump sprayer.

. . . . and then strain it through a pair of panty hose into our pump sprayer.

How did you clean the panty hose? Or did you just not wear them again?



sorry, couldn't resist

Baby, my pantyhose always smell like molasses, whether I've been pouring concrete or not!
