i find that a quick going over with a grinder gets rid of grease and leaves a good welding surface

don't use brake clean, it gets into the porous cell structure of the steel & when you weld it emits a toxic fume thats very bad for you. there was a big thing about this earlier this year. use carb cleaner instead or white spirits.

A grinder will get it clean enough for arc welding, you only need a light pass with it.

clean off then burn it out with a torch.By far the best way as it always works.

unless it is literally covered in half an inch of grease and you are welding a nuclear reactor core or something equally critical i have always found that as soon as the weld is started the grease burns off well before it has a chance to interfere with the weld, wipe it grind it weld it

GRINDING GREASE . LOL yea whatever . mostly just heats it up a smears it all over the place Degreaser / Petrol / Kerosene / turps depending on what you have available & the type of grease then simply hose off with water. Do your grinding & welding after that.

depends what it is if its a grease covered quick hitch i will steam clean it before i start.if its a stuck bearing shell that you are running a weld around to shrink it a quick wipe with a rag will do.otherwise i generally wipe it with a rag, burn it off with the gas,quick grind and your into it

There's stuff out called Grease & Wax Remover! It's good for cleaning up every other thing that could be covered in greasy stuff. Then there's another product out called Wax & Grease Remover, but that all depends on what you wanta remove first and foremost.
Or just turn the power up.

NEVER USE BRAKE CLEANER!Read This linkhttp://www.brewracingframe- s.com/id75.htm
Thats pretty bloody serious, and would be a very easy mistake to make. This should be a warning in its own thread. Will someone do that!

Scary thing is i've used brake clean before welding as its easier to spray and walk away than get thinners and rag etc Now i know better! cheers

jeezus, thats a horror story
I actually got out of my chair and checked a can of cleaner I use regularly
good ole supercheap Australian Export degreaser - had to go online to find the actives - not listed on the can appears itis 60 % white spirits, sigh of relief - but then this popped up

that one is already in the wheelie bin
water blaster and wire brush has got to be a option

chroming is the vapor coming off a hot exhaust, or the piece I'm welding after giving it a clean and wipe - and thatscommon occurrence
