How to Lighten Dark Stains on Furniture

Trash To Treasure

I love using oxalic acid (wood bleach) to lighten dark water stains and damage that sanding alone doesn't remove. This vintage solid wood table was in desperate need of attention, and I painted the base and revived the top.

AI GeneratedAngie from Transcend Furniture Gallery restores an antique solid wood dining table to raise funds for the 10,000 Carats Rabbit Rescue. Through a \"furniture flip for the bunnies\" event, her Facebook community votes on the design. The process involves intensive surface restoration, bleaching, and finishing to transform a damaged piece into a modern treasure.
Hello everybody! I'm doing something a little bit different again today.
I don't normally do dining tables. This one is an exception. I'm doing it for a
very good cause, but I thought I'd bring you guys along
on the transformation. This is a nice antique solid wood table, but you can see
there are a ton of finish issues and water stains,
so I'm going to do what I can to get rid of these. But first, I want to tell you
why I'm doing this. 10,000 Carats Rabbit Rescue is a rescue
near and dear to my heart. I do a lot of fundraising for them,
including this table. Every few months, I do what is called a furniture flip for
the bunnies, where I take a piece of donated furniture
and through a series of online polls on my Facebook page,
people can vote on color, style, and just basically guide me into a
finished product, which I then sell tickets for to raise money for the
rescue. So I do this every few months. If you want to check these out,
you can find me on Facebook under Transcend Furniture Gallery.
When I do one of these flips, I make a separate event for it so you can follow
along that way if you want to. No pressure. One thing I will mention
though, if you do want to follow along, make sure you're clicking the discussion
tab under the event or you won't be able to
see all of the posts that I make and the polls that you can vote on.

Okay, now let's get on with the flip.
My name is Angie and I'm the one behind Transcend Furniture Gallery,
a business created from the love of vintage furniture and the desire to take
broken, dated, and unloved things and turn them
into modern treasures. Sometimes I paint and sometimes I don't,
but I always do what I can to save old pieces from the trash.
Welcome to my workroom. This solid wood tabletop is an absolute
disaster. It's clearly had many, many, many years
of love and wear and tear. Most of the finish
is completely gone. The finish that remains is not intact,
so obviously it all has to go. Luckily this is scraping off quite
easily and I'm able to get a better look at the damage to the table itself,
most likely from heat and water. Those are the usual culprits on a dining room
table. Just using a stripping pad here around
the edges to get this curved detail clear of the residual stripper and a
slightly finer stripping pad on the top with some
mineral spirits just to make sure I have all of that stuff off.
It'll also give me a better look at the damage I'm dealing with here
in terms of discoloration, which you can see a fair bit of in the middle here as
well as on the drop leaf areas. I'm going to be
using a product called oxalic acid, which is a wood bleach,
but before I do that I need to sand down the first
layer of the table. You don't want to take it all the way down to your finest
grit before you do the wood bleach because
you will need to do a light sanding after the wood bleach, but you just want
to get that top surface off before you apply the
oxalic acid. I'm noticing also a few areas where
there are some deeper gouges and scratches which is
not at all uncommon on a tabletop. I'm going to be using
a damp rag and a hot iron without steam to try to
press those out and just a few other areas here that are going to need some
wood filler. So basically how this works, the water
and the heat will cause the collapsed wood fibers to swell and
sometimes they'll swell up enough to become flat with the rest of the
tabletop and sometimes they don't, but I've had pretty good luck with this
technique in the past so I'm going to give it a go here on this table.
It's really hard to see on the footage here but it is
actually helping. The fibers are starting to swell
and the depth of these gouges are getting less.
So now I'm going to mix up my oxalic acid. You want to use
hot to warm water and there's no real exact guideline here. Everyone sort of
does this a little bit different in terms of measurements but basically what
I do is I add it until it stops dissolving in
the water. And just a quick peek at these gouges
again. I'm hoping you can see here that they have raised a little bit.
Applying the oxalic acid, there's no special way to do it. You just brush it
on basically. I should totally be wearing gloves here.
I have no idea why I'm not in this shot but
yes, always wear gloves when you're dealing with this stuff.
It's also helpful to take a stiff bristled brush to help
work the acid into the worst areas of the stain. It will help loosen and lift
it. You never want to use it only on the
stained area. You have to use it on the entire
top of whatever you're doing or the entire area. If you don't you'll have an
area that bleaches out and the rest won't and it'll just look strange and
you can't really fix that. I'm letting the acid completely dry on
the surface while I go ahead and do some cleaning on
the legs in preparation for painting. So the oxalic acid has dried now. You
can see after one treatment that the stains are quite a bit less.
It's very important that you wipe off the oxalic acid.
A good rule of thumb is to give it two or three wipings with water afterwards
just to make sure you've gotten all of that off and then you just let
it dry. Basically you want it completely dried out before you start
your next sanding coat which I'm about to do here.
This 220 grit sanding should help smooth out any of the remaining
scratches and gouges and this is about as good as I'm going to get this
tabletop in terms of staining. You can do up to two coats of oxalic acid but
after two if it's not working it's just not working.
I'm using a little pick here to get rid of
the previous filler that they had in these holes because I'm going to be
adding some new fresh filler and I want to make
sure that any old crusty filler or oils etc are out of the holes so
the new filler adheres properly. Now that these patched areas have had a
chance to completely dry I'm doing my final sanding coat which is 320 grit.
Just a bit of a note here the finer you sand your
project the harder it will be for stain to
penetrate the wood. In this situation I don't want
the stain to get very dark so 320 is perfect.
It's a nice smooth finish and I want to keep
this tabletop as light as possible. I'm using Minwax Classic Grey here and I'm
basically just wiping it on completely and then wiping it off.
Normally there's about a 10 to 15 minute penetration time
and you can play with that a bit if you want it darker or lighter but in this
case I want it fairly light so I didn't leave it sitting for very long.
I just want to point out because it looks like this table is rocking all
over the place I only have the legs hand tightened right now they're not
fully tightened so that's why there's a little bit more movement than
there probably should be. I'm happy with how this top has turned
out it's an old piece so I don't want it to look like it just came
off a showroom floor. I want it to still retain some of its character some of its
dings some of the discoloration didn't fully
come out and that's totally fine this piece has a history it's got
decades and decades of family dinners and
report card readings and you know that kind of thing so I don't I just want to
preserve that while at the same time giving it a fresh
new look and finish that will protect the
wood for the next however many decades. I just
gave these sides and legs a scuff sanding in preparation for paint
and now I'm just cleaning off any residual dirt from the
rest of the piece and sanding dust and on to my first
The folks from the Facebook page had voted for a dark colored base so
I opted to go with coal black from Fusion which is one of my favorite
colors it does go on a little bit streaky with the first coat but the
second coat always does the trick. I've mentioned in a few of my other
videos but I'll mention it again here in case
people haven't seen those you never want to go too heavy on your first coat
a little bit of a streaky coat is actually a good thing if you put it on
too thick you're not going to get the proper adhesion
so you've also seen me use odi's oil in a couple of my other videos I wanted to
show you what it looks like fresh out of a new
jar it's very thick almost like honey before you use it you need to make sure
you stir it completely until it's more like
liquid honey this just ensures that all the ingredients are mixed well
and this is basically what you're looking for here perfect
a little bit of this stuff goes a long way and after I'm done applying the
first coat I'll show you how much I actually used you'll be surprised
it's a small jar but it really does go a long way so all you do
is apply it with a very fine grit sanding pad you want to make
sure that the sanding pad it's not like sandpaper it's um
it's an abrasive pad you want to make sure that the grit on that pad is higher
than your last sand coat so on this one I'm using an 800 grit abrasive pad
over a 320 grit sanding which is perfect in this
situation I'm going to be applying a second coat of odies oil in about 12 to
24 hours just for some extra protection and here on the legs I'm using
fusion beeswax hemp oil mix which I love using over
paint and here you can see I've barely used any of this this is one coat
and as I said I'm going to be doing a second coat but yeah a little goes a
long way this sweet little table is pretty much
done I'm just removing the excess odies oil from the top
and we're gonna call this piece finished time to sell some tickets and make some
bunny money this sweet little girl you see here is
Millie she's one of our four rescues from 10,000 carats and
thank you guys for watching this video no it's a little bit different where
it's a fundraiser but tickets are underway now it's been about
