Removing Blue Loctite

may have said:

Is there a common and safe solvenet that will disolve blue loctite? I want
to clean up the threads on a couple Al parts, and don't want to use steel
wool, or anything really abrasive on the Al parts.

Would a chain biodegreaser work?

Most types of Loctite are forms of cyanoacrylate glue with a mix of
fillers and setup time modifiers. In most cases, you can use a
superglue remover to get it off. (Acetone sometimes works, and is
often sold as superglue remover.)

Degreasers are unlikely to have any effect in my experience.

Gasket removal and paint removal compounds, on the other hand, are
likely to work.

Hmmm. How, exactly, are you defining "safe?"

Safer than methylene chloride AKA dichloromethane. I think the
original poster was considering the safety of the aluminum parts so
something like sodium hydroxide solutions would be definitely OUT
(NaOH dissolves Al).

Whatever you do, don't heat the parts. Aluminum temper is destroyed by
the heat necessary to remove thread lockers.

Okay, but in my opinion any characterization of acetone as "safe" should
come with some sort of disclaimer 🙂 It's nasty stuff.

Safe enough to be used as the principal component of a product
designed to be applied directly to the human body on a
regular basis, like nail-polish remover?

Acetone is not nasty stuff...the human body can metabolize small
amounts safely. Unless you take a bath in it, its not a problem.
Diabetics are another story since ketosis generates ketones, of which
one is acetone. People without diabeties also generate ketones but to a
much less extent.

Dihydrogen monoxide? Well, sure. It's directly responsive for the deaths
of over 3000 people a year in the US alone!

Evelyn the dog, having undergone further modification, pondered the
significance of short-person behavior in pedal-depressed panchromatic
resonance and other highly ambient domains... "Arf", she said.

nothing removes anything. this is a basic law!
no seriuosly...
step one - a wire brush at speed rotating slowly does the job. scca
regional cleanyness

step two - paint thinner leaves residue that's removable with CHO.
cycle cleanliness. good for locktite applications prep. use two clean
rags for 2-b. repeat with CLEAN wire rotating brush. cleaning with a
used brush does no one any good. the oprative factor here is the brush
rotating evaps the [censored] from duh grooves with friction.

step 3 - acetone wipe off off paint thinner possibly following the CHO
wipe off with two rags. wannabe rocket engineer grade.

yawl find that acetone doesn't actually remove loctite, the acetone
brittles loctite maybe preparing the locktite for...
drumroll please!!!

the knife. run a knife down the threads. a utility blade? a sharpened
bent spoke. spokes take a nice filed bent point to fit custom dude!!
take a comfortable seat and carefully remove the stuff. use a good
light.

final absolute law: mechanical removal beats chemical removal every
time. and use a softer metal brush on aluminum. ask the hardware store
man. keep in mind that the aluminum part will depart soon enough for
the same reasons.

Got a heat gun?
Works fine!
-tom

Heat gun on threaded aluminum isn't a good idea. Most aluminum derives
its strength from elevated temperature aging. Even a lowly heat gun can
over age heat treated aluminum, causing it to lose most of its strength.

Fasteners are no exception.

A soak in solvent like 2-propanone (acetone) and mild brushing with a
coarse Nylon brush will get it off.

Also, threadlockers are a methacrylic ester, not a cyanoacrylate ester
as posted earlier. Similar but not the same soluability. Methacrylics
will soften but not dissolve.

a first step is awareness that under the locktite is a fairly clean
surface if that's a virgin factory piece your taking apart. The
factory has a system to avoid the legal problems associated with
granny';s bike coming apart in an intersection, veering right across
the path of three state patrol cars going to a funeral below the legal
limit...
or it might be your prepared surface, so you shud know?
the idea is not to get the underneath covered with unclean solvent
after peeling the loctite of with a sharp edge. this leads to the idea
that solvent and wipe and dry before scraping is a good idea.
after scraping the lock out, more clean solvent and thinner then CHO
will do it gives just about all the grip one needs.
unless yawl taking the F-150 across the chiwawa at 130. loctite has a
website that informed sources imply now has some data on it.
The idea that extra clean surfaces add up to 20%, 30% or more
meaningful grip is uh unknown as quantifiable data but taken for
granite by everyone cepting those who don't have the time and
generally DNF.
there are exceptions that include the thinner/cho wipe and go on to
thinner/acetone: the pulley bolts using red locktite, that F-150 front
end, and bad environment, long term placement joints such as the
pedals/crank where sealing the moisture out and narrowing the goo
depth resting between(like its there right?, get the scope out!) are
one and the same as not having the joint loosen and rip off yawl's
testicles.
then there's the obsessive compulsive as with the pulley bolts. small
thread areas need the red lock: the blue doesn't hold it. But
improving on this problem is no problem using acetone. the acetone
emulsifies that in between surface into small solids or congealed
liquids-there's some [censored] seperation going on there, no longer a
continuous film, at leats. this gives that scoped metal surface(
unless yawl have italian equipment) of grand canyon like microscopic
revelation. "no virginia, its not a smooth"
that's where the acetone gives grip. exposing the grain gioves the
locktite a surface to grip into and a surface that will tend to
prevent water seepage and then following that loctite separation from
the surface as the O2 pushes the stuff up and away.
whew!
the cable screws? if yawl wipe the glop away. yeah not into the groove
stupid, away from the grooves then unscrew drip blue or red into the
gap, do yawl thing and screw the garbage coated fastener bak in then
that shud do the job holding the cable with just a tweak of torque
past snug. try that with the pedals and yawl be singing soprano!!!

on using acetone for female threads: clean the sufaces out with the
knife or spoke following a paint thinner wipeout(and then CHO if yawl
goin to indy) THEN thread a rag piece into the hole. pour acetone onto
the rag soas the acetone goes down thru with gravity. maybe crush foil
over the joint to...
walk upwing and let sit.
