Hallo Folks,

I've bought a part degreaser. (40 gallon)
Does anyone have experience with it?
What degreaser do you use?

Kind regards,
Jonathan

I use 28sec central heating oil in mine. Cheapest option I find, just wear propper solvent proof gloves and keep it off your skin. Many heating oil suppliers will sell from the pump if you're not on oil at home.

That "environmentally friendly" degreaser you buy in 25L drums is
a complete waste of time..... diesel is better and less flammable than petrol of course...

I usually have some old petrol drained from a car around the place, that does me for cleaning things quite often Smile

Don't use petrol unless there is nothing else. Old petrol is less volatile . I was once stood with a gallon petrol tin , in my hand, and flames coming out of the top. I took a few steps and threw it on the ground, it did not explode. I did not get burnt at all. What saved me was , it was a very hot day and the tin was full of fumes. There was no air/petrol mix to cause an explosion.
Another guy I knew, was cleaning the engine on his ute. with petrol. Before he cleaned it off he dropped a spanner onto the battery. His arms were badly burnt trying to put the fire out.

I have been told that if you put parts into molasses it will remove the rust without damage to the metal. You need to leave it in for a week or two to do it's job.

I use white spirit. Easy to get and works well, especially in one of those small pump units.

As with anything that has fumes....I do it outside in the fresh air!

I try to make sure that the only toxins I put in my body are curry & beer!

Whilst not a degreaser, a molasses solution will remove corrosion, I have a tub of it in my workshop that stuff gets chucked in to; http://www.oldclassiccar.co.uk/forum/phpbb/phpBB2/viewtopic.php?t=4892&highlight=molases

I tried molasses a few years ago. It does remove rust , it smells like a brewery after a while. If you leave cast iron in for a long time it causes the surface to soften and smear. It works best at warm temperatures and is very slow in winter.

Nowadays I use citric acid mixed with water, I buy it off ebay and find it cleaner and very penetrating. I believe it is the basis of Bilt Hamber Deox rust remover.

The initial question was about a cleaner fluid and I would go for paraffin, The trouble is it does leave an oily film. I wipe over with meths if this is a problem

hello, i have had rather good succes with elyctrosis for heavy grease, paint, and rust removal. simply fill a tub large enough for the part with water, throw a bit of washing soda in ( i guess about a couple tablespoons per gallon, doesnt hurt it one whit to put to much in Smile ) hook the part to be de-rusted to the Negative lead of a direct current source ( battery, battery charger, DC welder) and the positive lead to a sacrificial anode ( any old scrap steel will do). chuck every thing in the tub, making sure nothing is shorting out of course, and let it bubble! it dosnt take very long for it to start showing results. depending on the size of the part, distance between electrodes, and amount of washing soda, it should draw about 4 to 10 amps. 4 amps will take a while to de-rust but works nicely, 10 amps will make the water boil, so make sure to keep it topped up Cool

oh just a few notes, washing soda can be made from baking soda by heating it in the oven for about an hour at the highest heat, it decomposes at around 120 deg. F. into washing soda.
also remember to clean the positive electrode every once and a while as the rust builds up on it pretty thick, in affect insulating it.
this process works really well, it doesnt harm the base steel, but sure blast the rust and grunge off! Cool

I must try this electrolysis method next time I need to degrease and de rust some old junk, have been researching a bit on it lately and it looks the best option, cheap and effective.

Carburetor cleaner is great for degreasing / cleaning smaller jobs, and handy as its in an aerosol, you need to be careful as it will also take cellulose paint off, it would be very expensive for big jobs!

The firm I have used to have things like engine blocks cleaned uses caustic soda in heated water, it does a great job, but being such a strong alkaline its very nasty stuff, probably not practical to set up tank in the kitchen Wink
