Cleaning Cast Alloy

[Piggaz]

Had a look around and can't find what im looking for.

Basically I want to know the best hands down product for cleaning/washing dirty engine parts. You know when they get old and scummy.

I'll use a gearbox as an example. From looking like this..

Get it looking like this:

To this. (If only it turned into a Holinger after cleaning). I realise it's not going to be prefect but if the best product is petrol and a brush well that's the answer. But someone might have found some awome product.

Annnndddd GO!

Shelly's degreaser is a good start.

But i want to know if there something better then petrol for finishing

You're not going to get a finish like that short of media/soda/vapour blasting

super duper degreaser, let it soak, hose down, reapply, oh and a scower pad

Caustic soda.

Yes, don't get it on you. Yes be careful with it etc etc. Don't leave it on there more than 5 mins or so to check the results.

Used it on VERY dirty Cat mining motors, with good results. May also use various acids, obviously in the right concentration.

I've used a combination of degreaser and hose, followed by autosol metal polish with a mothers powerball for above average results.

Thats a decent idea but the 'balance tube' has so many nooks and crannies that it would take a month of Sunday's.

I went down and bought some degreaser and a wire brush. Came up well.... Now its in the dish washer

I used a product called shock treatment degreaser. It would take off oily scum off High Voltage transformers after 40 yrs of build up. It would even strip the paint in places.

It was the best I could find for getting it off.

Where did you get it from Brad?

I use to get it from a big truck seller in Cavan SA. But doing a google search it looks like there is plenty of it around.
