Can I rescue (clean) a brush that's already dried?
 
Latex primer, dried onto a brush that was left outside by someone's oversight, possibly a few days ago. Brush user does not remember which day he used that one.

Any hope to rescue it, or not?

Possible....but the chemicals that will do it are not cheap (10-20 bucks USD)
And the brush will probably never be the same (actually, if it's a good Purdy or Corona, I can say it will not ever be the same)
There's little microscopic fuzzy stuffs on those quality bristles that pretty much get ruined by the chemicals used
A cheaper brush you might not notice...but then you'd be buying a $10 can of brush cleaner to save a $6.49 brush

If this is a latex primer, I'd just get an empy tin can that the brush will fit into and pour in some xylene. Let the brush bristles soak in the xylene and every minute or two, pull the brush out and work the bristles.

Take care not to use the same hand to work the bristles as hold the brush because the xylene might dissolve the paint or varnish on the brush handle.

What I've found is that xylene will dissolve latex paints much more readily than alkyd paints.

I think if you keep dipping the bristles and working them, the xylene will eventually dissolve all of the primer in the brush.

Still, it's going to cost $20 for a gallon of xylene to attempt to save a $20 brush.

Thanks...I figured if anyone would know, it would be somebody here...

It's my favorite angled trim brush. A nice Purdy one that surely was made just for my hand!

Sounds like I could get the primer off for $10-$20, if I don't mind scarring the microscopic fuzzies. Maybe we'll just get out the microscope and take a peek at the fuzzies on a brush that's still good, and compare with what's left of my poor neglected favorite. :(

I was hoping somebody would have a home-made miracle cure, like one of 1001 ways to use white vinegar and salt and peanut butter...

No such luck:censored: You need to go back to the paint store and get a new brush

Maybe should put the dried-out brush on display, as a visual reminder of the value of same-day cleaning!

Do you use a painter's comb on your good brushes?

Krud kutter
 
soak the brush in kk over night and take a wire brush to it the next day. If you use xylene let the latex settle and you can recover most of what was poured into the cleaning container/soaker. Xylene is caustic nasty stuff so wear gloves.

Beth777 09-10-2008 02:08 PM

This is the first I've heard of Krud Kutter, so I just looked it up!

I guess you mean Krud Kutter Brush Wash, rather than one of the many other varieties of Krud Kutter that show up on their website.

I wonder if Lowe's carries it.

skolfoppa 09-10-2008 02:32 PM

I use the original red label kk. It is a SW product.

brush gone bad
 
Well, usually the hard brush is garbage... You can try soaking it in water for a couple days and then using a wire brush on it. But, for all the time and effort it may be better to relieve the culprit of his duties and then buy a new brush....

In this case, it's better to replace the brush than the culprit. His hero status is totally still good at our house, without question! :)

My favorite trim brushes are under a new paintbrush protection plan now. We got it all worked out!

Lacquer thinner will not touch dried latex. I have used the Kwikeeze brush cleaner quite a few times and it works well but the brush is never really the same faterwards and I usually downgrade them a primer brush at that point.

I'm a little confused - we are talking about expensive chemicals and microscopes.... I understand it's your favorite brush but can't you just replace it with the exact same one? If its your favorite brush, I'm guessing you've gotten some use out of it. For no more money than you're going to spend on saving it, wouldn't it be nice to have a nice new one?

Matthewt1970 09-18-2008 06:30 PM

Na, the Kwikeeze is less that 10 bucks.
