Haven't tried it.
I'm using the ZEP rust remover from Home Depot. It's working well.
Need to find more things to derust and see how long it lasts. Haven't
been able to find any info on it.

That's a sweet solution, VBG

How interesting. I will certainly give it a try. My wife uses molasses
in breadmaking, so buys it in bulk. Cheaper still that way. Takes a
quart jar to the local health food store and they fill it.

Thanks,

Let us know how it works.

Since H2So4 does a nice job - I use professional plummer drain cleaner -
strong solution of H2So4.

Might be that the brand of black strap is containing sulfur - common.
Most state de-sulfurized.

I bet the de version wouldn't work.

I'm not a chemist, but I'm pretty sure most drain cleaners are strong

There are both lye based as well as sulphuric acid based cleaners.
Your Ace Hardware probably has a bottle of concentrated, 80%%, sulfuric
acid, sold as drain cleaner, that you can buy and use as drain
cleaner. It is very serious stuff and works very well. Dissolves human
hair, etc. Such a bottle lives on a shelf in my garage and I can
attest to its efficacy. It converts at least a part of the scum from
drains, into stinky H2S.

This isn't the kiddie stuff in the shopping centers -

This stuff is the real nasty stuff that eats drains if it has to.

Limited use from a plummer section.

It is used to dissolve proteins and fat/grease and melt it by a reactive
hot solution. I keep it out of the shop.

Puts a nice gray surface on scale iron - taking the scale off.

Normally it is lye and has and and converts grease into 'soap'.
When Drain-O and such doesn't work - the plummer pulls out the big Bomb.

And one drains lots of water afterwards less drains are messed up.

I remember when the cast iron pipe that ran overhead in the physics department
split open. Seems that for years a slow and ever present drip of acid from
all work stations (chemistry lab) above us ate the bottom of the pipe out.

Replaced it with Quartz that is really protective.
