Gosh. To much science involved for me. Use Navel Jelly I say :-\

Hi Oren,

Here is the short form of the explanation.

Naval jelly is plain old phosphoric acid (plus a wetting agent such
as plain old alcohol) which, when applied to my rusty tools, will
convert the rust to 'black powder', which I can then wash off.

Now I know how to clean up the rusty table where the tools lay:

1. Rust on the table

2. Pool acid on the rust

3. All the rust on the table gone

4. New concrete spots are the result!

The table is plastic. Easy

The concrete just etched. Porous

No?

Plastic is porous.
BTW why don't you spell it poros?

As in color (which should be colour)
