- well if you wanted to design something which corrodes steel
as fast as possible you would probably want to have a cocktail like
Ground up rocks, minerals and ores for a good coarse abrasive
effect. If possible ground up iron ore aka - ferrous oxide, aka -
rust , for a nice `starter' effect.
Strongly acid soil, say....... ph 3.1 to 4.5 (Did you know that
all the mountain, hill and moorland areas in England and Wales have
strongly acid soils?)
Or why not go to the other extreme and have an alkali soil?
Alkali can be just as corrosive as acid. If you are going to go for
alkali you probably want to go for clay (clay soils are usually
alkali) as well just so it clings ferociously. That way each time
you go out in the wet that dried on clay can get wet again and take
forever to dry out - so the rust worms are nicely fed with the
moisture which they need to do their best work.
To give the cocktail a bit more `zing' and speed things up how
about some enzymes in dung and ammonia from fertilizer. Throw in
some decaying organic material to keep the soil well aerated and
give the rust worms plenty of oxygen.
To top things off nicely you would probably want to add some
salt from Winter roads to really get things moving.
First Battery acid then caustic soda (alkali) and then salt do
not even affect the gloss finish on this KLEENtect panel

A KLEENtect coated panel and a galvanized panel were subjected
to this extreme test with the results shown above. They were first
dipped in an inch of battery acid for 20 minutes (ph 1) then rinsed
in cold water. They were then left in an inch of caustic soda
(alkali) solution (ph24) overnight then rinsed in cold water. They
were then left in salt water for ten minutes then left for a day.
Result: The KLEENtect panel was totally unmarked (KLEENtect
contains PTFE which is impervious to acid and alkali attack) The
galvanized panel was completely stripped of its zinc coating and is
You can do a safe and easy version of this test yourself:
You can do a safe version of this test at home. We can supply
an easy and safe to use KLEENtect test panel kit. For safety and
convenience's sake instead of a beaker of acid we
give you a bulb and pipette to put just a drop of acid or
caustic soda on the panel. ( Use the pipette to take a couple of
drops from your own battery. Or why not devise your own tests?.
KLEENtect will pass any test you devise with flying colours. To get
your test kit of a KLEENtect test panel, bulb pipette and
instructions send an addressed label and a cheque for £10 to:
