Hi Dennis & Yvonne,

STOP THE BUS EVERYONE, I brought a 250mm bottle of  Ranex by Bondall at Bunnings this afternoon for $12.29.  On top shelf under rust remover stuff. Read it five times Good for stains Not Good on painted Surfaces, colour bond, or Gal.

So slow and steady boy, we will do a test patch underneath out of site so to speak. Just a dab on a household spong. If this doesn't work I blow $12.29 ( I'm wearing disposable gloves) OMG it just started to wipe of before my eye's. Bucket of water to wash down residue.

OMG  its like brand new again like I had just picked it up from the dealer. I'm on a WINNER here. It says not leave wet, towel it dry. WOW WOW WOW. lets keep going. I just don't belive it. I have done one hour so far changing the water with each section.

By days end tomorrow, I will have back, my camper. JUST added $$$$$$$$$$$$$$$$$$$to resale.

The Ranex = Phosphoric Acid Trade strength. So far I have used 25mm of the stuff.

Im so excited I'm taking Lambie out for a feed.

Hey Jim & Lambie

Make sure you really wash it off well or after a day or two the gal becomes a dull grey colour.

Sounds like a red dust problem ????
if it is, try some aluminium cleaner It will do the job
Spray it on in the right dosage and Hit it right away with the gerny
good luck


Cheers John

Well I hope you still have some gal left by tomorrow.

from their website:
* Note: avoid contact with vehicle paintwork, Colorbond ®, dry concrete, anti-fouling paint, marble & anodised or galvanised surfaces.

 Mate; that is potent stuff. Used to use it back in the 70/80's when doing rust repairs on cars. When all the removing & replaceing of rusted sections we would sand off with a sanding disc ; then mix this acid with water about 10 to 1 & brush it on repaired area to do the final clean, let it dry then wipe off with a damp cloth to leave a coating, very good result before any filling was done.

Dont try spraying it; the fumes will kill you.

How strange this should come up, only a few days back I ran into a guy that ran a chemical store at home where we used to buy it from & had to think hard as to what the name of it was. LOL

If you're all excited about using phosphoric acid, you could have used Coca Cola. 

It contains phosphoric acid. Good stuff.

PS: use a old tooth brush to scrub it into the metal. It lifts as you watch.You MUST keep the water up to it. Slow as you go. Small section at a time.

Yes,I remember phosphoric acid for rust treatment.It used to come in a black fluted plastic 500ml bottle with a red top.I think there is still one on my shelf in the shed.Good stuff when prepping rusty steel prior to painting.Wash it off,let it dry,fill,undercoat and paint.Great stuff.Just be careful it doesn't effect surrounding paintwork.

There are many different rust removal and rust treatment products available that contain phosphoric acid, with differing strengths. Even, as someone else mentioned, some softdrinks contain small amounts of phosphoric acid.
