Disposing Of Used Paint Thinner

Okay, in this day of being not only PC (politically correct), but EC (environmentally correct), how does one “properly dispose” of their used paint thinner?

In the “old days” we’d just pour it down the drain, or out in the driveway, but given that I am sure that today that is a “big time” no-no, what is the correct procedure for disposing of used paint thinner?

Or for that matter, how about how do we properly dispose our empty paint bottles, glue bottles, tubes, etc., etc., etc.

I can honestly say that I’ve NEVER had to dispose of any old paint thinner. You see, I’m a frugal kinda guy and make use of everything, even old paint thinner. There’s always some weathering to be done using “dirty thinner” or when blending paints, old thinner sometimes comes in handy to lighten or darken to acheive the desired color and/or thickness.

Otherwise, does your area have a Household Hazerdous Waste facility. They’ll take it off your hands.

I start by saving all the used and dirty thinner in a labeled plastic milk jug. When the jug gets pretty full, I take it to the yearly hazmat collection that the township has. That way I know that it is disposed of correctly. As for empty paint bottles, glue bottles and tubes, Same procedure.

SWIM have been reported pouring in down an ant bed or on stubborn weeds growing in cracks on the driveway. Don’t milk jugs pollute the environment too?

If you really want to be PC and EC then find an environmentally friendly paint so you don’t have to buy/use paint thinner.

I guess better just end my comment here as I don’t want to be banned. I’ll leave it up to the reader as to how I would suggest disposing of these items. If it aint broke don’t fix it.

Good points made by all, guys.

I would suggest you check your local ordinances, to find out what they recommend, as there is a very wide variation in the UK between local municipalities as to what they will & will NOT allow.

I Switched to Acrylics purely because of the smell.

My leftovers from that are from paint cleanup, rags, newspaper, masks, etc, which (in the UK) can go in the normal bin, & the water in the spray-out pot, which I pour out into a cardboard box & bin when dried out.

BUT I still have small quantities of Cellulose Lacquer, Mr Surfacer, Humbrol metallics & thinners, Acrylic Lacquer rattlecans, etc, which I try not to use in quantities large enough to generate lots of waste.

When I used Humbrols, I had two tins of thinners, one fresh for err… thinning & final cleanup, the residues from that went into a sealable jam-jar & allowed to settle, & then decanted into another jar for further use.

Jim,

Saving it up in a milk jug or whatever and taking it into the town as part of their disposal process is probably the best thing to do. The same with the empty or partially empty bottles of paint and/or glue. Unless of course said bottles or tubes are labeled with instructions on how to properly dispose of them. But sadly, the printing on the Testors paint bottles is just too small for me to be able to read. [;)]

Jon,

You idea of saving the used thinner and then decanting it to be reused along with saving it up and turning it into one’s local community collection site are probably the best way (or at least one of them) of disposing of ones used thinner, paint, etc.

^Good answer.

If one is really frugal, one can pour the dirty thinner into a jar/can and let the solids settle on the bottom. Then, the top “clear” part of the thinner can be poured off and used for enamel paint clean-up of airbrushes or brushes.

On the idea of saving used thinner and decanting it for later use, I think that probably pouring it through a coffee filter to further remove the solids might be a good idea as well.

I have a coffe can with a small vent hole poked in it, and the inside is stuffed with paper towels. I dump old thinner in there, and the towels soak it up. and when it evaporates i just change out the towels and throw them away.

Texas Gunner,

Thank you, I hope that it helps others.

Use it to light the BBQ.

This is more of a ponderance than anything but I wonder if places like Lowe’s or Home Depot will take back old thinner and/or paint. Maybe I’ll contact them and find out.

Thanks Gary, yeah I forgot that one. I do that as well. In fact, I usually have thinner in 3 stages of usability :

FRESH: brand new or just a lil bit cloudy

NOT SO FRESH: stuff I’ve poured off the top that’s still basically clear but starting to show some color

and

BLAH … WHY THE HELL AM I KEEPING THIS: the thick stuff that’s never going to be fluid again. I actually use this to adjust tone and thickness, create oil stains / fuel spills, and finally; mini molotov cocktails that I’m hoarding for that imminent day when I finally declare war on the wife’s doll houses

I have never had to dispose of old thinner. I reuse it until its too thick to paint with . Then I use it to fill in ground work on dioramas or use it as loads of dirt in railcars.

Also comes in handy for the 4TH of July Bad builds! Which happen all year long !

Not trying to be a wiseguy,but isn’t the sediment leftover on the paper towels hazardous also ? So simply throwing the towels away would create an ecological problem also ?

Believe me,I’m not casting stones-just asking ?

Not really sure?? It’s probably not 100% enviro-friendly, but its dried paint. What do you do with sanding dust when re-painting cars or other things, or after you’ve chemically stripped paint off a car or airplane? Makes me wonder what these professionals have to comply with?

True,you can go crazy with this stuff

Just make sure that your wife doesn’t read this post. Or she and her dolls might storm your supplies in attempt to keep you from declaring war on the doll houses. [;)]
