I have never cleaned any white ones but Lowes had a closeout sale for
some kind of plastic drip edge to snap on so they never get streaky
again. They had a big drum full of them but they are probably gone in
the trash by now.
I've tried the following, applied with a saturated paper towel to small
test areas:
-- full-strength bleach
-- full-strength Simple Green
-- full-strength white vinegar
-- full-strength TSP substitute
-- 91% rubbing alcohol. Some improvement, but labor intensive to do all
158 feet.
-- paint thinner
I've also tried the following:
-- spray gas log cleaner
-- spray Fantastic
-- a mix of bleach with Oxydol laundry detergent, applied with brush.
Makes some improvement.
-- a mix of 1 part Simple Green, 1 part bleach, 2 parts water, applied
with a sponge. Makes some improvement.
I haven't tried ammonia, since I don't have any in the house.
I admit that I haven't had the patience to wait 5 to 10 minutes for any
of the above to work. I was hoping to find something that I could apply
with a dust-pan brush and have the streaks magically disappear
immediately. Any suggestions?
Thanks,
Ray
I know it sounds crazy but just use some Dawn classic dish washing
detergent and a broom. Works great that's what I use on my white
gutters.
I recently did some with the same problem with some house wash from the
Borg. Applied with fairly flexible brush on a handle. Let it sit maybe 5
minutes. Rebrusheded. Rinsed.
Happen to have pics of the difference:

If, as you say, you don't have the patience to wait 5 to 10 minutes,
where did you get the patience to repeatedly not try it once and
continually fail?
If your time is that valuable to you, hire soemone. If they fail it's on
them.
Slang. Any of the big box stores such as Home Depot or Lowes
I used to use "Scrubbing Bubbles" and an old sport sock to remove the "black
streaks" from my RV
Spray it on .. watch the stains go from black to gray to orange to
yellow to GONE.
Rinsing is optional, but I usually do it just to keep any nasty chemical
reactions to a minimum.
This stuf is GREAT and has to be the best kept secret around.

It sounds like the stains are oxidized aluminum. Repaint.

Not my mildew. I soak some white outside chairs in a strong
solution of Clorox every couple of years. just wiping it on full
strength does nothing.
Never tried Jomax- but it is now on my shopping list.

I painted mine with semigloss white exterior latex paint. They don't get
as dirty as before and just clean up with soap and water.
It'll probably takes less time to paint than the time it takes for you
to clean them.

The house is a ranch, so most of the time I stand on the ground and use
a saturated broom to reach the gutters and most of the siding. When I
was trying to spot-apply the various solutions above, I only had to go
up two steps on a ladder.
You have to be careful with some cleaning solutions on aluminum gutters.
The gutters have a very thin coat of baked on paint.
I used a product that was meant for cleaning plastic garden furniture,
because it also cleaned almost everything else that regular cleaners
could not, and after spraying it on the gutters and wiping it off, it
started to dissolve the baked on paint and I had to stop. I then
repainted the gutters instead.
> It sounds like the stains are oxidized aluminum. Repaint.
Definitely not oxidation. When I tried rubbing alcohol applied with a
paper towel, it made a noticeable improvement, but took a lot of
pressure. Also, that would be expensive to treat 158 feet.
Overall, the first thing I tried (bleach with laundry detergent) made a
noticeable improvement, but not as much as I'm looking for.
Alcohol would probably have softened the paint and might behave as you
describe. There is a difference between dirt and stains...oxidation,
polution, roof runoff, etc., can cause stains that become part of the
paint film.
The stuff I had used was even labeled something like eco-green. I was
surprised how well it worked. Lucky I guess. When I initially but it on
and brushed, very little came off. Letting it sit for 5 min (without
drying!) then rebrushing was like magic. Like I said, just lucky.
The stuff I used to use was ZEP Patio Furniture Cleaner ( found at HD).
Unfortunately, ZEP doesn't make it anymore, but I found a another brand,
Spray Nine Patio Furniture Cleaner, which seems to work as well.

Alcholol won't soften the baked on paint of the aluminum gutter.
Go to Ace Hardware and buy a gallon of their aluminum siding cleaner.
Takes that stuff right off.
