I used to use the flux brushed for glue but switched to the silicone
glue brushes that Wood Craft sells. Yellow tip, Black handle.

I bought 2 and have been using the first one for 10 plus years. And
Yes I saw the second one yesterday. LOL

Easy to remove the glue if you for get to wash it out.


Might work pretty good for plumbing flux too. Disposable brushes are nice,
but it just feels like such a waste when you're only doing two joints.

I'll have to look for those. How much does the silicone flex?

Puckdropper

Quite a bit. They have approximately 30 little fingers that are about
3/4" long.

Silicone is the latest rage in cookware. I have a couple of brushes like
yours for basting, buttering, etc. We also have some spatulas, stirring
spoons, etc. We haven't tried any of the muffin tins or cake/loaf pans, but
I keep thinking about it. I see them used on the cooking competition
shows all the time. The food items just pop right out, like a ice from
a plastic ice cube tray.
Well for baking silicone has been around for quite a while, at least
10~15 years. I bought my wife silicone muffin tins, bread pans. She
pretty much hates them. So they tend to break down and become sticky
over a period of time. What ever is oozing out is oozing out in high
temperatures into your food.


Are you talking about 15 YO muffin tins or modern day muffin tins?
Well since she had the bad luck she has not bought any more hoping that
it got better.


Compounds have probably improved.

Maybe but they are still silicone unlike the examples you mentioned below.


On the other hand, it's possible that one might confuse a sticky residue from the
food with the breakdown of the silicone. Like I said, I've not tried any silicone
bakeware, so this may not be what you and the missus have experienced. I can
say that I have experienced sticky residue on metal cookware over time.
No, the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet.
Trying to clean that goo off damaged the surface.

I was gluing on some edging last night and got to thinking about the
silicon brushes vs. silicon muffin tins.

I'm just tossing this out, not trying to prove my point. It's just a possibility.

In this response you said:

" the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet."

In another response, you said:

"Ambient room temperature being the relative constant and the
silicone breaks down on its own. Oddly, the silicone brush and
small silicone container have not exhibited this condition."

OK, so what's different between these two situations? One obvious
difference is the use of oil and other food stuffs when baking but
not when gluing.
Sooo the really big difference is the high heat that the baking dishes
are exposed to.

It could be possible, that based on the articles I quoted, the muffin
tins only felt clean when put away but the unfelt residue eventually
changed it's chemical structure (polymerized, perhaps?) and turned
sticky.
What ever is going on, the silicone baking pans, heat breaking down the
silicone or residue from baking not actually coming off in the
dishwasher but still feel clean we choose to not risk the possibilities
of what was going on.

I've had cast iron skillets turn sticky if not used frequently enough.
Granted, they are put away with a slight coat of oil on them, but it
could be possible that the silicon muffin tins also had a very slight
amount of residue, even if cleaned as thoroughly as possible before
being stored.
Possibly but then they fail because they do not come clean and the
silicone breaks down.

The way to test that would be to put the brushes - or at least the bristles -
through the same cooking and cleaning process and see if they eventually
get sticky.
They probably would. But our silicone utensils, if not exposed to high
heat, baking, hold up with out getting sticky.


Either way, our experience with the silicone after being baked was not a
pleasant one compared to the metal equivalents.

Gotcha! Makes sense.

The things you think of while waiting for glue to dry. ;-)

Aren't these silicone utensils all dishwasher safe? If so, I'd try
diswashing them to remove the varnish film. You may need a
phosphate-bearing detergent, as used in commercial establishments.
