I use Scotchbrite (pan scourers) to clean off the rust and oil it
after.Cheers

Dave, as Mark said earlier, you can use scotchbrite pads to get rid of
the rust. Avaialble in several different grades from fairly abrasive
to non-abrasive 'polishing' grade. Have a look at the J&L site and
type scotchbrite in for the search.

For rust prevention of tooling in medium or longer term storage, I can
happily recommend a product which although quite expensive, is very
effective indeed.

In the injection moulding business we spray all the working surfaces
of our *extremely* expensive mould tools with a moisture guard product
when they come out the machine and before they go onto the storage
racks. Bear in mind these mould tools often have a very high diamond
polished surface finish, and a 0.2mm diameter spot of rust can mean a
rejected part and an expensive re-polish of the tool, so the stuff we
use has to be 100% effective.
The products we use are made by either Ambersil or Rocol, and these
spray a thin waxy film over the surface that displaces and repels
water and totally prevents rust. We have some mould tools stored
outside in a 20ft container for 2years, where the outside of the tool
rusted, but the working surfaces were as bright as new.

Links here:

Rocol

Not cheap, but a single can goes quite a long way, and compared to the
many £000's that a mould tool costs, a cheap solution for us.

for the ultimate protection ....

they don't tout this with their product

back to black silicone spray ...
it works very very well as a rust protectant

but has side effects ...
they are ...
if you ever do any painting in your workshop .......it will prevent
paint sticking to any surface ........even in the minutest quantities.

the stuff will coat every surface in the workshop (from the mist
drift) .....so can get on to all metals ...unknowingly ...preventing
you painting them properly in the future.

think that's why you don't see these polymer silicone sealants for
cars on the market anymore ...think the auto industry outlawed
them ...because ...they were having failing results with insurance
jobs

so if you don't do any painting ...or plan to ..........you can use
the stuff.

all the best.....markj

meaning that i must have done well on other threads .so will take that
as a compliment ...thank you .

aha ...the infamous tony morgan or rhyl-on-line ... strikes again .

haven't you got a good word for anyone

and why hide behind a disguise .

the outlawed info passed on to me by a painter friend ...

the stuff is not liked by car sprayers ..

yes you can still get the stuff .....but not as readily available as
it used to be . .

all the best.......mark
