Hello,

Have a bird feeder that is held against the glass window via the typical
soft plastic suction cups.

They hod, but only for a relatively short time; perhaps a day or two.

What is the secret to getting them to hold on longer ?

Moisten first ?

Light oil ?

Or,...?

Is there any kind, brand, or style, that perhaps works better, that I
can replace with ?

Thanks,
Bob

Yes, try moistening them

if that does not work, use a little clear RTV

Definitely.

Water. I'm not sure if that dries out or not. Try it for a couple
years and let us know.

Yes, they're called Watercups, and they're just like the one you have,
but they come packed in water.

Just kidding.

Moistening the suction cups will help them keep the suction by filling
the microscopically small roughness in the rubber cup. However, water
evaporates and once it does, you're back to square one. I would use a
very light oil like WD40 on the rubber cups and/or glass before applying
the suction cups. The oil will fill the roughness just like moisture,
but it won't evaporate.

Wet them and be sure the window is perfectly clean.
None are perfect, but bigger and thicker is better You may get a couple
of weeks, but I've never seen a suction cup last forever.

Won't the WD40 deteriorate the plastic cup, at least whether it will or
not is unknown.

Will mineral oil, olive oil, or such work?

WD40 is a crap-shoot at best. It evaporates like water, and depending
what the cup is made of, can seriously degrade it in short order.

Glass shops use glycerin on their rubber installers cups, taxi and
pizza delivery companies used glycerine on the suction cups of the
rooftop signs. It works good for sticking things to bathroom tile,
things like towel bars etc. It used to be on the instructions of many
suction mounted devices to wet the cup with one drop of
glycerine,spread thinly across the surface.

And it washes right off after you remove the suction cup - unlike RTV.

Like the RTV idea. Even if doesn't hold the vacuum seal, it should
act as an adhesive. Easily scraped off with a razor blade if it
fails.
WD40 is junk. Useless.
I've actually got a suction cup placed on a tile to hold my razor.
It's overdue to come off. Hasn't fallen off in more than year.
Only one I use. They're only for VERY light duty use.

Hi,

Thanks all for the suggestions.

Will give Glycerine a try.

Any idea where to get/buy a very small amount ?

Good point. And, cooking oil is readily available in every home's
kitchen.

I've had cooking oil go rancid.

I hang a humming bird feeder full. Clean the glass with Windex spit on the
cups, rub around, stick. I think my cups are still on the window from last
year.

I'd try a larger suction cup for starters. If you use delicate
application, clear silicone caulk would do the job.....make a template
out of masking tape, stick it on and trim if needed.

If you have a glycerin modem, you might even be able to get a free
sample online.

Or a solid-and-liquid modem. But they don't download as fast.

I like the glycerin idea. The suction cup which holds my Magellan GPS seems
to fall off about four times a year, usually when there is a sudden
temperature shift (it is sitting on the floor of the car right now). I'll
pick up a little bottle of glycerin the next time I go shopping and give it
a go.

Almost anything that is oily-based and not water-based should help. Cooking oil olive oil, even some of the oily salad dressings if yu are desperate.

Glass shops/glaziers could use it, but I was in the glass business for
25 years and I never saw a glazier use it. I never worked for a company
that even stocked it. Woods Power Grips last a LONG time w/o any
"conditioning" needed. The vacuum pump fails way before the rubber
surface does.

The plain old windshield suction cups sitting in my garage that are
about 15+ years old are almost as pliable as they were when they were
new, and they have only been cleaned with glass cleaner.

Rubbing alcohol to remove the oil. Wipe the rubber carefully. To much exposure can eat awy rubber

If that don't work use the opposite. Rubbing alcohol to clean the surface of finger grease.

Real rubbing alcohol has oil in it to keep skin from drying too much.

I finally managed to find a small quantity of pure glycerin -- not an easy
thing since your normal CVS/Walgreens-type pharmacy don't sell such
old-style things any more. I've re-stuck my Magellan GPS's bracket back to
the windscreen and now we'll see how long the suck lasts. It takes a
vanishingly small quantity to do the job. I used too much the first time
and the bracket just slid down the glass like a crawling slug before I even
added the weight of the electronics. Of course it didn't pop off so that
may be a good sign.
