removing white rust on engine

[honda_zivic]

whats best way to remove the white rust shit that builds up on engine?
i hose that bitch with degreaser but doesn't do much.

was thinking oven cleaner?

rust isnt and will never be white.....

got pics?

where abouts is it?

what you need to do is just go an buy like 15 cans of the cheapest degreaser you can find. You can get stuff from Repco that goes by the brand motortech, comes in a red aerosol can, that shit is the best stuff ive ever used, and its like, 2.20 a can, sometimes they come on sale, 6 for 10 bucks.

Just spray it on and leave it for like, 15 mins, then hit it with a pressure hose.

Make sure you protect all important electrical stuff, wrap a plastic bag around the distributor, etc

It's aluminium oxide. Just sand it off.

+1 for motortech - that stuff is awsome

btw its not rust - its just oxidisation - light sand and heeps of degreeser will get rid of it

if its around alot of hose fittings you may have a coolant problem

Rust probably isn't the right word as it generally applies to iron, but it's the exact same process --oxidation.

Give it a sand and with emery paper soaked in liquid degreaser.

I would also very much suggest painting the block to help stop this from happening again. :)

cool i give it a shot. thanks u people.

I use a wire brush and scotch brite pads. Works great

Applied Chemicals have an aluminum etch formulation, No666 from memory.
It will etch your alloy & leave it physically & chemically clean.

Just brush it on, leave for a few minutes, then hose off.
It will oxidize again within hours, & look similar to when you started in a few days, so good paint application very soon after it is dry is necessary.

It is the aluminun oxide on the surface of the alloy that prevents further corrosion of your alloy, so best not to touch, unless you plan to paint the thing.

ive found that you get an increase in this oxidisation from cheap degreaser...

Barcobe soda and boiling hot water does the trick

[dougie_504]

If you polish up the block it will protect it from some of the oxidation though, right?

[Bludger]

ive found that you get an increase in this oxidisation from cheap degreaser...this is because you are cleaning the metal and exposing the bare metal to moisture.

ahhhhhh good point mate... :-)

For shits sake. Please do not use words unless you know what you are talking about.

The word barcobe does not exist in the English language. I'm pretty sure the word you are looking for is bicarb, short for bicarbonate.

Please refrain from posting until you have a solid grip on this language.

Wash/sand of and get some of the 3M rust+prime stuff from supercheap, it stops rust and does a mild prime of the surface

LMFAO at trism... be nice mate... LOL
