How to cost efficiently clean rust from steel plate

I don't know about cost effectiveness. I tend to use a wire wheel on a grinder. On flat surfaces, the cup wheel style works best for me. I asked a Sait salesman once about it and he suggested a flap wheel sanding disk on the grinder - it works, but sure seems like a lot more time and effort. There are some of those 3m type fiber disks that I have not tried.

If you had a better education, you would be able to respond without using profanity.

I mean, if you want the cheapEST way, then yeah. Any electrician, or even construction worker will tell you that, maybe in any language you want, too. Wipe down enough with any kind of car engine oil and it can make old, spider-webby, rusted rigid, emt pipe, strut or troughs and clamps look as good as new.

(I've never seen this done this with copper, brass or aluminum conduit, clamps or other supports, though - just rigid and emt)

If you have a lots of sheets to do, and have the space and can deal with the mess, sand blast them.

rent or build the equipment yourself.

I kind of like the chemical idea, also, because it takes comparably little work. I will try.

Now that you say it, I have a Tennant style brush with metal bristles. I will look into how I could use it.

Buy some steel cup brushes from Ohio Brush. They are very very good, will give you excellent service and will last a long time.

Or have a sand blaster do the work for you at considerably more money.

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie

It's already been done! And, can you guess who did it? Oh yea...that would be me. Mostly used to clean/prep metal roofs for coating.

Of anybody, YOU could probably build one! Can I have a prototype! Could you add an "IRRITATE" setting for me?

Why are you always so negative?

So what would be you first choice?

Then it is a little hard to understand why you infest this group. It is basically a group for those who want to discuss recreational metal working and is hardly where one would expect an ineffective computer programmer to be found.

I wonder if you could do it electrically? Say with a large piece of cloth s aturated with PH Up from a swimming pool supply and a power supply. Pos sid e of the power supply hooked to a piece of sheetmetal, laid on top of the s aturated cloth, and the neg side hooked to the plate. I do this with smalle r parts in a bath often and it removes rust quite well, but slow

The choice to exclude profanity from one's vocabulary has nothing to do with his quality of education.

HAHAHA!!!

--instead, you sit on usenet blathering about profanity....

In your case, the intelligence and knowledge are clearly there regardless of profanity. Some others seem to resort to profanity because they have nothing to say.

There are some youtube videos that are good, but in most cases the video is slow compared with reading. So in general I skip the videos.

Nice. What kind of rpm can that handle? You don't make something similar that would fit on a long arbor buffer do you?

I have a hard time with your logic. Iggy has not presented enough information to make a first choice, yet you can make a last choice.

Based on Iggy's previous posts, I would expect that he is thinking in terms of three of four in a month and getting them clean enough to be part of a welding table. And the size is what turns up so could be from a couple of feet square to maybe as large as 4 by 10. So perfect is not needed. Hardly worth setting up sand blaster and dip tanks would just take a lot of room for not much use.

Some times it is..other times the reading material is worse than the videos.
