cleaning orchid leaves
 

I just read in the rec.gardens.orchids archives that many people use 'milk'
to clean their orchid leaves? However, while at least one post claimed that
there is no smell, another post claimed that as a result the smell can be
very strong. Hmm. Since I live in a small apartment I don't want the place
smelling of milk gone bad. Has anyone out here now used milk, and if so,
does it smell or not?

What is the best way to clean/dust leaves in your experience?

Thanks,
Joanna

Joanna,

I have used milk, and detected no after odor. However, we grow outside, so
it might not be as noticeable. Nevertheless, mild dish soap and water works
very well for me, as does alcohol. The milk seems to give the leaf a matte,
'finished' look. So, if I'm going to show a plant, I'll clean it up with
Ivory or alcohol and then give it a light rub with milk.

Thank you Diana and giorgio.

Giorgio, welcome to the group!

I may try the milk or milk mixture someday -- if my husband David will let
me, since we share the same apartment after all, and he is very concerned
about the possible smell. He suggested that maybe orchids like milk only in
that, after applying milk, they stink and then one needs to apply a fan, and
they like the fan. :-)

So on second thought, I might try the mild dish soap first and see the
result. If it is good enough, I might avoid disconcerting David and not use
the milk after all.

Thanks,
Joanna

As Mick was so kind as to post the url of the "best" orchid site, I'll throw
my hat in the ring with Rise & Shine as an excellent leaf cleaner / shine,
with some apparent insecticidal properties as well.

And if you don't like the commercial, check out the "Home Remedies" for a
few other alternatives.

Doesn't just a damp cloth and water clean dust and stuff off them?

More often than not, it's the mineral deposits from hard water that have to
be removed, not just dust -- that's easy.

Bolero,

I guess I am just trying to be a bit more perfectionist here, and trying to
clean off the "water stains" and make the leaves look shinier/newer/fresher.
Mostly I think it's spring fever (the weather was really glorious like
spring in the DC area today, and maybe that made me think that spring
cleaning should be started, or something). Also I got two new orchids
yesterday, and their leaves look cleaner than my older ones, which did have
dust and/or water stains. I did use a damp cloth first, but the result was
not perfect, the leaves still looked like they could be cleaned better.
Probably I am just fussing over the orchids too much.

Ah that's why I didn't understand.

We have soft water here (around 60 to 80ppm) so we don't get mineral
residues on our leaves.

Thanks for clearing up that one.

No not really, if you get mineral residue and stuff like that it makes sense
to wipe them off.

I don't think you can ever fuss too much........;-)

A friend (and very good grower) uses that CLR cleaner stuff. I suspect
the "Lime-Away" brand would work just as well. I used to use acetic
acid at about 10% concentration. I don't know how this would work on
thin leaved orchids...

I searched this thread for somebody who said "lemon Juice." Yippy.
Currently I am using 'Real' Lemon Juice, straight out of the bottle.
"Real", in this case is the brand name, but it is 100% lemon juice. I keep
a bottle of it out in the greenhouse right next to a roll of papertowels.
It works well on all the orchids in my greenhouse, thin and thick leaved
types. Never seen or smelled a problem from it. I used to use lowfat milk
and it does make a neat shine on Phal leaves. Can't leave a bottle of it in
the greenhouse for when it is needed. Must retrieve a small saucer of it
from the frig when needed. "Oh, you have cats?" "No, this is for the
orchids." One time I used a fresh saucer of milk to clean up plants I was
taking to show off at the society meeting and in the car on the way there I
could smell old milk proteins quite distinctly. It didn't take long, as I
had just cleaned the leaves with it, and I was kind of surprised at the
strength of the odor and the short time from actual use but there was a
smell of rotting milk that could not be denied. Maybe it was just the
confined space...

Hmm. I don't have any CLR around, but I just checked the bottle of

acid, which is pretty strong. Does he dilute the CLR? Just curious.

Not as far as I know... I've seen her spray it right out of the spray
bottle on the plants. You would get denaturation of surface proteins,
if the acid were strong enough, and maybe some other interesting
chemistry. But that is at the surface of the leaf. Thick leaved
orchids usually have a pretty thick waxy cuticle, so perhaps an
occasional acid wash wouldn't do much harm? I certainly wouldn't bathe
my plants in it every day...

Actually I think that while Lime-Away and CLR recommend gloves, they
aren't particularly dangerous to bare skin. As long as the contact is
brief and you rinse it off. Vinegar is something like 5% acetic acid,
and I spill that on myself all the time with no obvious effect.

Take it with a grain of salt. Don't blame me if you kill your cymbidium
with it. I'd bet good money that you couldn't hurt a standard cattleya
with battery acid, as long as you wiped it off right away. I can't
remember enough organic chemistry to know why I think oxalic or acetic
acids are less dangerous than sulphuric acid, but it seems to be
entrained somewhere in that grey sticky substance in my skull. Probably
as wrong as everything else in there.

That's interesting, Rob. I don't know that I'll use any of those products

Joanna, there was another posting in here once that talked about
this. Somebody said they used mayonnaise, I tried that with a Phal.
that had hard water stains and it looked more like it covered up the
spots instead of taking them off. But somebody else said tea. I tried
that and was amazed, want to know if it'll do the same for my arteries.
All this talk of lemon juice and hey I'm boiling some water and getting
out the tea bags haha. Burr

As the most likely mineral deposited on the leaves is calcium carbonate, any

that and was amazed, want to know if it'll do the same for my arteries.
All this talk of lemon juice and hey I'm boiling some water and getting
out the tea bags haha. Burr

As the most likely mineral deposited on the leaves is calcium carbonate, any
acidic solvent should work to one degree or another.

Joanna, there was another posting in here once that talked about
this. Somebody said they used mayonnaise, I tried that with a Phal.
that had hard water stains and it looked more like it covered up the
spots instead of taking them off. But somebody else said tea. I tried
that and was amazed, want to know if it'll do the same for my arteries.

I'd bet good money that you couldn't hurt a standard cattleya
with battery acid, as long as you wiped it off right away.



Dare you to try, Rob! Post pics on ABPO! ;-)



I guess somebody else will have to try it, I can't get ABPO. *grin*

Hmmm. What other lame excuse can I come up with... Actually I
don't have any hard water marks on my cattleyas... There, that is a good
one. And true, since I use only RO water... And I don't really have
that many cattleyas.

Although since I've been called out on it, I will donate a plant to
science and see what happens. I'll even wear gloves. So, with a low
number of replicates (1) it counts for beans, but how about this for an
experiment...

One leaf washed with 1N sulphuric acid (battery acid - IIRC,
although to be a true test I should use the same concentration as in a
car battery. Anybody know?)
One leaf washed with 0.1N sulphuric acid
One leaf washed with 1N acetic acid
One leaf washed with 0.1N acetic acid
One leaf left unwashed

Observations at 0,1,3,7, and 14 days.

I can't get sulphamic acid (actually I can, but I'd have to wait
several weeks to get it), and I don't think I have any oxalic acid.

I think I have an old Hausermanns yellow cattleya that has enough
leads on it to try the experiment, although it isn't particularly well
grown. Any other conditions I should try?
