paint removal

[MulderMan]

anyone got a good formula for paint removal on clothes. its enamel paint on a pair of pants. tried turps, meths but that hasnt worked. any ideas?!

[YT2095]

have you tried Acetone (nail varnish remover), it`s a long shot, but it may work

[budullewraagh]

pyridine

[MulderMan]

pyridine

 

although that probably would work as a solvent, i find it quite hard to breathe next to pyradine . ill give acetone a try, ran out of the good stuff so ill have to use nail varnish remv.

[budullewraagh]

and it's like $200 for 150mL. oh, and it's highly controlled in the us at least

[akcapr]

try butoxyethanol and NaOH. I heard those can do it

[Flareon]

Might as well buy new pants!

Actually, for automotive enamals (and most enamels used for metallic surfaces), the best solvent is probably dichloromethane (aka methylene chloride). It's cheap in the US (about $10/gallon) and very effective. You can get it at just about any auto-parts store.

 

However beware. If the clothing has synthetic fibers, DCM will happily dissolve those as well. Acetone should also work fairly well, and wouldn;t be nearly as fast as DCM.

 

Use in a well ventilated area. Not too healthy to breath it, and it evaps pretty quickly at ambient T and P. (I assume you don't plan to do this in a vacuum or hyperbaric chamber )

 

Pyridine ? That's one expensive solvent, plus, it is a scheduled precursor. Listed on the DEA schedule 1 precursors list (not the same as the controlled substances list).

 

Of course, you could make your own pyridine if you're so inclined.

try butoxyethanol and NaOH. I heard those can do it

 

I'm sure there is a good reason, but lye? On fibers? Why?

[akcapr]

good for greasy paints

[budullewraagh]

well, it wouldnt be good for the fibers

[H2SO4]

CH32SO (DMSO, a.k.a Dimethyl sulfoxide) might works. Supposedly it an extremely good solvent.

[akcapr]

wat u do is u get the solvent the paint came in.

[H2SO4]

it might be hard to find that though.

 

Start out simple, did you try rubbing alcohol, gasoline, white gas.

 

If you want to get super complicated and Mind me for saying this, im just throughing it in here for discussion, Liquid propane.

[budullewraagh]

dimethyl sulfoxide would make the pants smell pretty bad though

[H2SO4]

Ive never used Dimethyle Sulfoxide, does it stink that bad, it is a sulfur compounds?

[MulderMan]

is that the thing people get high off, im sure ive heard DMSO before.

[YT2095]

it`s important to remember that not ALL paints when dry are re-soluble in their original solvent

[budullewraagh]

yes, dimethyl sulfoxide is a sulfur compound:

SO(CH3)2

[ecoli]

I've used cooking oil (canola) to get paint off my hands (oil based paints, of course)...

 

Would it work for clothing as well?

[asalem]

hey i have paint on freakin most of my clothes and i take this dumb painting glass and i need to know how to get away paint from jeans, cotton shirts. Does anybody have an answer

[woelen]

As long as it is not yet dry, you can use white spirit, but of course the fabric must withstand the white spirit. Dried paint is very hard to remove and then I think it is cheaper to buy new clothes.

[woelen]

yes' date=' dimethyl sulfoxide is a sulfur compound:

SO(CH3)2[/quote']

DMSO is completely odourless. I have some of this and it is a colorless, somewhat oily and odourless liquid. When it is reduced, then it becomes very smelly:

 

(CH3)2SO + 2e ---> (CH3)2S + "O(2-)"

 

The dimethyl sulfide has a very strong smell of garlic. If you ingest some DMSO (some people do that, I don't although it is supposed to be quite good for your health to take small doses of DMSO), then you get a garlic smell.
