Removing rust on block
 

What would be best way to remove rust on engine block. Rust is surface from leaking radiator hose. Thanks.

Tried to add photo today 8/14 but site asks for url. There's no URL, I would simply up load directly from PhotoShop if allowed. Not allowed.

Thanks to everyone that responded. Will try the recommended methods & products.

is it dissembled? Is it painted? Will you be repainting it?
If it's disassembled I would use a light sand paper, or wire wheel.
If it's assembled In order of effectiveness:
If it's just a rust stain try soap and water first.
A product like CLR or evaporust may help, may damage the paint. Soak a rag and lay if over it.

Pictures would help if possible.

Thanks. Assembled. Hope not to have to repaint. Will post pictures probably tomorrow Fri.

Like post # 2 posts, try soap and water with a Nerf soft bristle brush in an inconspicuous place 1st.



Check and see if evaporust/thermocure/ rust 911 is safe on paint. Whatever you come up with test it on a non visible part of the car 1st.


CLR/vinegar/etc./anything you are supposed to wear rubber gloves is slightly acidic and would mar the paint

Powdered wood bleach (oxalic acid) mixed with water. Available at most hardware stores. Doesn't mess with paint. Wet, scrub and rinse.

a good penetrant,like kroil will allow you to wipe the rust stain off

Try an oily rag, I've cleaned my engine of coolant stains, dirt ,etc , it will clean and leave a shiny finish !

CLR or other rust removers will also work.

I can't envision removing rust and not having to repaint.
