Paint stripper for Acrilics

[Paul De Tourtoulon]

Hi all, I broke my trusty 30-year-old glass reservoir for my Humbrol single action aero graph, I found that the Tamiya acrylics paint jars are the same thread, but how or what do you recommend for cleaning out the dry acrylic paint ?.

 Thanks, Paul

Yep, the small Tamiya acrylic paint jars are the correct thread size for the common Badger airbrush bottle tops and enable you to have multiple, thinned paint colours in usable containers, just swapping over between a few screw caps. For cleaning out the dried acrylic paint inside the empty jars you could try isopropanol, which I also use for thinning the Tamiya acrylics themselves or windscreen washer fluid, which I use neat for cleaning the airbrush between uses. Funnily enough, that is exactly what I'm doing this morning.

You could try soaking them in neat Dettol, though I've also read that oven cleaners and even brake fluid can work. I think Deluxe Materials also have a paint stripper in their range.

Cellulose thinners dissolves most acrylics apart from cured 2K acrylic.

Cellulose thinners should work.

Dont forget to consider the substrate when talking of things like 'Oven cleaner' & 'Cellulose derivatives '. Many foams, adhesives & plastics dont always like such strong liquids.

Paul is wanting to clean out glass jars!

[Paul De Tourtoulon]

Thanks to all, I have some old brake fluid to start, then cellulose, then oven cleaner, but maybe just good old wire wool and ajax ?.

I tried the last, last week. Well dry for a long time, and very hard work.

You may also use acetone.

 

I always use this for all the dried paints in jars and airbrushes.

[Paul De Tourtoulon]

Thanks to all, the brake fluid did the job, now to see if it will get rid of the dried 2 pack polyurethane paint.

[Don Fry]

For 2 pack, I would, when the wife is out, put the jar in an oven going flat out. Hot enough for the chain molecules to start breaking down, and give your solvent a key to do its work.

[Paul De Tourtoulon]

It isn't thick paint, I gave it a wipe and left it with a bit of acetone in it, which has evaporated.

[Don Fry]

But you still get long chain molecules in a 2 pack. Solvents pick at the end. Heat the things to shorten the chains, more ends to pick at.

Non technical, but you see the shape of the argument?

So you're liberating those short chains by heating them up and the resultant vapours then contaminate the internal surfaces of your oven, so that every time you heat it up, you liberate more of those into the air inside the oven and potentially onto your food? No thanks.

Same thing as putting epoxy into the microwave to warm it up, instead of just using a bowl of warm water or a hot air gun.

[Don Fry]

Not sure about the science of some of that, but hey ho.

Standing outside on a breezy day, upwind of the jar, heat it with a blowtorch. Don’t melt the glass. Take care not to burn fingers.
