Cleaning M100B Dome aluminum crud

[andylevine]

I'm cleaning the trim from around the dome on a 100B.  The weatherstripping stuff cleaned off fine with Simple green and some muscle.  The black rock hard glue stuff however is another issue.  Got a good chunk of it off by scraping with putty knife and hot water and Dwan, but it is rock hard, stubborn stuff.

Anyone know what will dissolve this ancient black putty stuff???

Hi Andy,
My favorite thing to use in cases like this is, Di-no-might. Just tape it to the edge between the glass and aluminum, light the fuse--run like---- ! Works every time--no crud left that can be found !
All kidding aside, if the original "Miracle- Black Magic Tough Glue",is still there, nothing, I know of, will dissolve it.
I have just worked it off using a case cutter, with a strong blade--cut as much as possible along the edge, and begin chipping it off, using a razor (straight edged) against the glass. Ron Rich

LOL...Rich...DY-NO-MITE!!! would surely do the job, but I dont want to have to invest in a new dome at this point I just spent the last 45 minutes with a can of GoopOff Pro, a putty knife, and a whole lotta elbow grease and the two side pieces are now GLEAMING (see pic here: imgur.com/a/gXIsP )

not sure how to get the long pieces as clean as the U Channel is FULL of this stuff and it harder to get in there. I may soak a rag in the GoopOff and let it sit in there a while then do as you said, use a box blade or an Xacto straight down. I don't want too many leftovers in channels before I put them back on the glass. I've heard nightmare stories of the hard stuff cracking a dome after the fact.

Andy,
Wait--I did not realize you had the glass out of the frame ! You MUST remove every last trace of the original glue that remains in the frame--If you miss any speck, you will have a broken glass sometime in the near future, if not instantly ! What are you going to use to replace it ? Ron Rich

Ron,

I have the original dome. I guess I was lucky I didnt break it removing it from the frame. I planned on cleaning the edges of the glass today, then was going to use black silicone in the frame pieces to secure the dome back in. Remount on the cabinet and let it sit.

Hi Andy,
Yep-- I have had them fly into pieces upon an attempt to remove the dome frame--HINT--be 2000% sure that all screws removed are put back egg-zact-tly the same way--length matters here, in both the frame and the piano wire hinge to the cabinet--ZERO "strain", in any direction allowed-- After re-installing, the dome, lock it and leave it sit for at least 24 hours--
BTW--the ONLY use I have ever found for "WD-40" is cleaning that goop off the glass, and the frame-- ("Goo Gone" works too--either way allow the stuff to sit in the channel/on the glass for a while--softens it up--) Ron Rich

Ron, the piano hinge I removed has 1/8" foam on the middle similar in nature to the stuff on the frame sides, just not as wide....about half the height of the hinge. Is this normal and necessary to replace??

Hi Andy,
Well sorta--That's there to prevent "spills"--if in a home environment, probably not needed, unless you place a plant up top !
