G'day All

Is there any way you can make old galvanized steel look newer ?

I've tried a few concoctions off the net to no avail and some polishes I've already had but none seem to do anything.

I don't expect 15 year old galv to look like new but was just hoping to freshen up some galv bits on my camper.


Cheers

Hi Gazz,

What is the actual problem..... is the galv stained or is it just dulled.
If dulled, then that is oxidised zinc and mechanical buffing could brighten it up a bit. A stiff brush, some Solvol, water and elbow grease may do it. If that seems too daunting then power brushing with Dremel or cordless drill may be the thing.

But, as others have said; painting over could be the way.
Cheers

G'day Allan

No real problem, just a cosmetic thing now after making other stuff look new !

Think I will paint the rear wheel carrier tomorrow as there is not much masking involved and I still have paint left from painting the storage doors.
It's either that or make love to the missus before watching a movie on netflix :)

Cheers
Gazz

Google how to clean g/steel, a number of products come up which are available from Bunnings.
If it's rust you want to remove, try Ranex Rustbuster, works wonders.

Silver Frost Mate!, Thats what the caravan dealers use on their used van chassis, and anywhere else they can poke a can in.

I did paint the galv jerry can holder frames in a silver coloured satin paint and they came up a treat.
They were removable which made painting easy but to do all the rest would require lots of masking up, time and patience - and I don't have one of the above lol.

Maybe down the track a bit.

A weak hydrochloric solution will cause action on discoloured gal. Test on the surface first of course. Wash off immediately after use with baking soda /bicarb solution to kill any residual. Weak Hydrochloric is used to clean car engine bays by second hand dealers.

I remember using that to clean up my old aluminium tray tops years ago and worked well - might do a test spot underneath somewhere and see how it goes.

Much like you Gazz tried a few things. A tin of Cold Galv and a paint brush seemed to be the best solution.

Thanks David

I just recently purchased the camper and tidied a few things up, fixed and tweaked a couple things. Then painted the doors on the storage compartments - then the old thumb latches looked crap on the new paint so new latches were bought and fitted and all of a sudden my 15 yo Campomatic is looking almost new again.

So that's when my ocd kicked in and I thought what can I do to the galv coz that's about all that is left that looks old ! Think I might look into painting a bit further down the track.

My son in law reckons the way it looks now I could sell it and make a few grand profit out of it lol

Cheers

On old Landrovers with gal trim capping - the use of vinegar lightly rubbed in with plain steel wool worked well but dont expect it to come back like new.

That would be the Acetic acid content of vinegar I presume.

Gazz,

What about CLR, that stuff that does wonders on one's shower roses & other bathroom fittings?

Some of the lads at work have been detailing a couple of old prime movers for the recent Winton Festival, and swear by Purple Polish for alloy bull bars. Might work on your gal bits? There's a precleaner available too, by the same mob that makes the PP. Available at Supercheap, I believe?

We've tried some acids, suitably diluted, on prime movers, and while the surfaces are cleaned up, they tend to lose that shiny finish.

Are you sure CLR does what it says? I have used it/tried it a number of times on shower screens, rust, scale etc for the purposes it claims to do work on, it has NEVER worked in any way, Followed,
directions and NOTHNG happens EVER! A Complete CON of a product.
I did get some results with weak Hydrocholoric though, not for everything of course.

Hey RMD

You are spot on with CLR - bought a bottle once and used it on everything it said it was good for !

Crap product !!

I would have more chance of putting out the sun with a water pistol than CLR cleaning my shower !!!

CLR stands for Calcium,Lime, Rust, but is really "Clear, Liquid, Ripoff". It sounds like we had similar results with that fantastic product. It didn't even shine my boots!

Hi Frank

I've been using Truck Wash for quite a few years now - cleans my vehicles extremely well but I was just after something that could possibly make the 15 year old galv look 5 years old !

After all the replies and lots of dud results - I'm thinking painting is the way to go.

Thanks

Gazz - I think repainting will be the best option. On Galv though, use an etch primer first. A hammered metal finish over that will be very durable if you like the look.

Thanks Kerry

I used etch primer on the jerry can holders when I painted them - then 3 coats of satin silver and they came up a treat !

Also used an aluminium etch primer on the chequer plate storage doors - then 3 coats of dark grey paint followed by 2 coats of clear and I couldn't be happier with the result.

This is something I don't do often but I can't stop now - just gunna keep painting now lol

The problem with anything abrasive is that it will take the gal off and next thing you have rust coming through.

Can the parts be unbolted? Last time I got some stuff done it was around $10/kg to get some stuff hot dip galvanised. They came up like new... because they were mill finished steel when I dropped them off.

G'day Hoyks

It was a rear swing away wheel carrier which I wanted to freshen up. Well over the weekend I cleaned it, etch primed it, painted it with three coats of colour then two coats of clear and I am very pleased with the end result ( and the quality of workmanship lol)

Thanks for the reply

Two products to try.....
Shower Power, spray on ....leave for five minutes then gurney
Or
Diggers Rust & Stain Cleaner (Oxalic acid) (available from the Green Shed)
mix up a solution spray on and gurney off after five minutes.....excellent for removing red dirt stains also!

Good luck
