I have 30 sash that need a clear finish, the old shellac has reached it’s decay point (S) so, here is my quest.
This church would like a clear fin. to match existing…no problem, right?
Chlorine, Oxalic, Oxy clean, sodium pentocholrate..peroxide..what ever…I still have muntins, with this…any H20 / chem mix gives me…celluose, cotton like degradation…not too good with Sugar pine..
seems the alt is to rout out the offending stained profile ( an ogee) and replace w/ a new sticking/glass retainer…
The outdoor side is retained w/ applied sticking..no putty.
These are S/P glass..about 40 yrs old. Moisture condensing on the glass has caused the muntins and mullions to lose the shellac ( yes, I know it’s shellac, smell it)..and the MIgration of the shellac has made parts VERY dark, while the raw wood, was exposed..
so..what now? say you.? I am inclined to rout out the bad and make new sticking..btw, I am using MOW spar for new fin, after the redo..even tho’ it’s interior, the condensation is brutal, no?
I have attached a few snaps for y’all to peruse…don’t laugh, my shop is a mess..thanks D

can't get any picts from your attachments - - the presentation of the post is different than others, also - - dunno - you tryin' a macIntosh?...hell, even this reply box is different than normal - wrong color even - - maybe the mothership is landing near you?
OK, somehow your post at breaktime is linked to this one - I replied out of the breaktime post and the answer appeared here - - I'll see if I can open the attachments from here....
well, I can open the attachments here - -
maybe alcohol/steel wool the shellac, then oxalic, then steel wool/custom scraper the fuzz?
yup, I C/P to BT...musta FU'd..
uhhhh, the steel wool was first barrage...kinda not happy with the results..but ANY result might be better than the Cotton fuzz, I have,,
am thinking to finish it first, THEN refin...????
edit...I ground new scrapers..they just gob up..with/shellac/cotton

O.K. stupid ?'s here. Did you try sanding the offending dark spots? Have you used alcohol to strip the old shellac? Did you try alcohol on the stains to try and lift them a bit? You might try some alcohol wiping, then wipe down with clorine bleach then set in the sun for an hour or so and see if you get some improvement. Paint stripper has also worked for me in the past to some degree.

P.S. clean that shop <g>
Restoring the past for the future.
answer to 3 of 4..no
I jumped on the bleach...(wrong, I know)
reamalglamating was my last thought ( always the best it seems)....
man, I just made a good study in not what to do...LOL
this is #1 of 30 sash, and I picked the worst to start with...make my boo boos now..almost easier to rebuild than refin.
Thanks..I'll go back to the exterior infusion of alcohol, the interior version, still ain't cuttin it..
here's to ya.

The quick way would be to strip/scrape them bare, and stain the sashes dark to cover up the discoloration.
or;
Try using peroxide bleach, also some oxalic. If you're getting real fuzzy(the muntins), try using less and doing it in a few lighter doses. Let it dry, and lighlty sand between.
I wouldn't consider re-routing(that sounds like a disaster waiting to happen), but would try scraping with profiled scrapers.
Thanks Dave, the crux here is the old shelac is SO gone..I thought of strippen the bastids..but it's a waste..of stripper and time.
This one is the basket case, and I knew a price for ALL of them would cover the easy and hard...but, restaining, (other than an AMBER /Nat..) is not gonna happen..all the trim/sills are old sugerpine..with a coat of shellac..which has failed, miserably, throughout the house...
being a parsonage, for a large church, I am tryin my best for a lowcost/ make a buck/ happy community..right..it'll happen.
I will tackle the next one with scrubbies an alcohol, what the hell they dusted w/ like sillicone might be fun..
lemme email about the other stuff we discussed..OK?

It will get to be a lotta work routing those out. I would clean them up with alcohol, sanding and then touch up with glaze/toner. That's work too but I could do it faster than the routing. I could even paint and faux-grain the moldings quicker than replacing them. It does take some skill and practice to do it that way though.
However you do it, I hope it works out OK for you. I hear you on the 'do a good deed thing/still make a buck'

Otay
Sphere,
Several of my Anderson windows were in similar condition due to a faulty thermostat/humidifier combination control. I wonder is Anderson or Peachtree, etc. would have a solution that is less aggressive. Are they double pane?...if routing, would swapping out the glass panels be in the budget?
nah, they are Single pane, that's partly why they are in this shape, and also why I can't see putting TOO much ummph into a window barely worth the fix-it-charge.
I'll do the alcohol scrub with a scotchbrite and keep on with that route..and forgo the router out plan...it does sound like too much of a hassel.
Unfortunatly, my NEXT job IS doing just that..swapping out bad insulated panes that are totally captured in the wood sash. Plan on a top bearing flush trim bit with a plywood template and square cut out.

If the shellac is truly gone on ALL the surfaces then you will need to bleach the dark stains. If it isn't gone it should be easily removed using 00 steel wool dipped in denatured alcohol. I would definitely do this first on all surfaces. It will also have a smoothing feature--open the steel wool pad out to use the most surface.
After that then bleach the discoloration--try fresh Clorox first--or swimming pool bleach. This will of course, raise the grain so sanding is next.
I hope you'll consider varnish rather than shellac for the finish--water has been the culprit here obviously and shellac will just do it again.Gretchen
Thank you kindly, I am using your approach as we speak, and so far, it is looking a lot better then yesterdays result.
The chlorox does really make the grey, very white, and it becomes pure cellulose!! Kinda like cotton.
I am using Man_O_ war spar for the new finish...that oughtta do it.
I also nabbed some itty bitty scotchbrite abrasive wheels for my dremel...seems like it can be a handier thing than I thought! I can run the wheels over some 36 grit floorsander paper I have, and renew the clogged face. Hmmm, I might be on to somethin here...LOL

Whoa, the cotton effect isn't good. You might just try the shellac removal alone and look at what the wood looks like when you wipe it down with the denatured alcohol. Maybe the dark will not look too bad with a clear finish--the color while the wood is wet is what it will look like approximately with your varnish finish.Gretchen
it seems the degradation has gone too far..the cotton like fibers used to be wood, now rehydrated? Not pretty...I'll post another shot of our brainstorm..not too bad. I gotta let the batts fer my camera recharge...one of those days.
