i mixed up 5 gallons. i put in a really nasty rusty 383-4 intake that sat outside for a really long time. it came out awsome, but i didnt want to remove it until i figured out what would work to nuetralize it. it sat in the tote a few days i put some brackets in it yesterday and the stuff is dead. didnt touch the rust on the brackets. so yeah its cheap to make but, 20 bucks to derust and intake manifold, im not sure if its really worth it. evaporust seems to last longer.

Soooo, Has anyone tried this stuff out on something that has an aluminum component attached?? I have some carb bases that are a little crusty and was wondering if they could be dipped to clean up the rusted parts.... Anyone have an idea

Here's a box I've made for trying this on a rear valance. I'll post again when it's done. I also thru in some c-clamps to take up space. I put in 9 gallons of the "juice"

lined with 2 layers of plastic

ready to fill up

Looks good but your going to want to remove the paint off the valance before you dunk it...it wont remove paint.

Just trying to remove some light rust.

Framing square and clamps turned out pretty good. Rear valance needed to be flipped over, it'll come out tomorrow.

I'm on my second batch. Works quite well for me. I put parts in when I get home in the evening and then pull them out the next evening after work. Garage is cold this time of year, and I don't have time after work to get the sandblaster going, so this way I'm able to a little bit during the week.

I have also used this with great results.I mixed one gallon first to try than mixed 5 gallons and as i took parts out that were ready i added more parts to see how long it would last.I ended up using that 5 gallons for three weeks and cleaned a lot of parts.I put it in a plastic tote with a lid.Was nice and warm out then.Have not tryed it in the cold.

Glad to find this thread is still active and it's great to see what you all are doing with it. I was reminded of it just recently:

My 7-year-old found this same mixture in a paperback science book for kids showing them how to turn tarnished pennies all shiny.

It explains that the acetic acid in vinegar changes into hydrochloric acid when it mixes with the salt. Same as stomach acid. No mention of the lemon juice.

He drops a penny in and 10 seconds later it's shiny. I will use it on a bunch of nuts, bolts, brackets.

If it hasn't been discussed yet, one way to neutralize the acid is to rinse the parts in a mix of baking soda and water.

couple of questions, jamesdart said his batch lost its strength after three days,anybody else had this problem? would putting in a sealed container help? i know my 22 dollar a gallon of evapo-rust did, reused three times.good for bolts, anything larger would cost a fortune. would heating up the mixture help(floating tank heater)we use one for the horse tank. as far as the cost, use the good stuff for delicate parts, the vinegar for the other, a no-brainer.

The valance cleaned up nicely, but had too much bondo, so I tossed it. As you can imagine, the longer this stuff sits around, the weaker it gets. I have a 5 gallon bucket of it that has been sitting for several months now. I put a few tools in it recently, for 2 weeks, they came out fine. If you're in a hurry, then it plan on it working for just a few times.

I used the mix and it finally lost much of it's strength after a month or so of it sitting open in my garage .

Neato!
