Hi all,
After using some Oxalic cleaner to help remove rust etc from my brake calipers i just wondered if it could be used to clean a block. I've managed to find a Tote box at work just the size of a block half so it would be ideal.

Any idea what acid cleaner is used by workshops?

 

Block's are alloy so I would make sure its ok to use on that first.

 

As above, and remember it's quite poisonous, won't you?

 

Used to occasionally wash the car with oxalyic acid disolved in warm water, back in the '60s when I worked for Fords at Dagenham. Before they installed filters, the sinter plant there would contaminate the area with minute metallic particals which would settle on the cars and then rust when it rained! When you consider you were also probably breathing in this stuff, it makes you realise how blase' we were back then!

Not as far as I know.
It was the Ford chemists who suggested it's use for removing the fall-out from the paint.
I recall it being used in the furniture repair and restoration business for removing stains and bringing out the grain pattern in woods.
