Something weird happens every morning when I start work.

If anyone watched me clean the first couple of windows of the day they'd swear that I have soap in my water as it looks like soap suds are coming from my brush.

The water is reading 00 and the windows dry clear, and the "soap" clears after a window or two so it's not a problem, just a bit curious as to why it happens.

My guess is air bubbles in the system somewhere.

Anyone else got any other ideas?

I get that when I am using my backpack. I am guessing it is some kind of reaction between the water and the hose as it doesn't look like air bubbles to me.

Its just air in your resin vessel it gets worse in hot weather
but nothing to worry about.

[mlscontractcleaner]

Yeah you're right, it has been more noticeable in this nice weather.

Like I say, it clears after a couple of windows; I was just curious to hear if anyone else had experienced it.

Cheers lads.

No, as the water is in my backpack and hadn't seen a resin vessel for weeks. It is some build up in the hose that the water washes through I think. I don't get it in my regular hose, just in the hose in my backpack.

Pretty normal, happens now & then.

[bobplum]

more likely cavitation.............this happens because you cleaning at super sonic speed your causing the water to heat up and explode into small steam bubbles.

You need to slow down 

(thats what i would tell the customers)

Air in the system either via a leak in hose or lose connections somewhere.
No probs.

Same thing has been happening with me only the first window of the day then no more . Mike

AFAIK it's caused by chemicals leaching from the pipe and acting as a detergent.  So they are soap bubbles.

New hoses suffer it more.  Pipes not used but full of water for a long time (e.g. overnight) have time for the chemicals to leach out.

I just use the brush to do the frames for the first minute until it's run through then go back and do the glass.

I have to say Vin, I've never heard such nonsense!! This forum is amazing at times, it really is!!

That's my impression. It isn't air bubbles.

What do you guys think water is made up of? I'll give you a clue- it's the O part of H2O.

I'm losing the will to live! Chemical release, soap, detergent? REALLY? LMAO

Did you just make that up for a laugh? You certainly have some knowledge everyone else is missing.
Bampot of the month post I think.

We have someone on this thread who thinks that, without a massive energy input, we are able to split oxygen out of water.  If you're right, by the way, you've solved the world's energy problems for ever.  Just run water through a hose so it splits into hydrogen and oxygen.  Then you have limitless fuel.

We have someone else who just gainsays what I've suggested.  No reason, I'm just daft.  

So, here's the background for WinPro and Ronnie.  A hose will contain phthalates.  I know it's a long word, but stick with me.  It's something that makes plastics flexible and long-lasting.  They leach out of the plastic they are used in over time (that's why the lighter ones are being phased out of kids' toys).  Oddly enough, one of their properties is that they are often surfactants.  Stick with me, another long word you might not understand, but have a look at the side of a bottle of detergent; it'll mention them.  They are the thing that makes foamy things foam.

So, we have a chemical inside the wall of hoses that is known to leach out of them and which also acts as a detergent.

We have window cleaners who have pure water (good solvent) in plastic hoses that foams if it's been left in there a day or two.

So, which is more likely to be a good explanation?

We've found a way to split the bond between hydrogen and oxygen without putting in enough energy
The person who just shouts I don't understand bampot
The chemicals found in plastics that have a property that would result in water foaming

Just remembered why I leave this place for long periods.

P.S. Winproclean, good luck with getting the O out of H₂O.  This time next year, Winpro, you'll be a millionaire and you'll have changed your name to Rodney.

That was a good answer Mate, I enjoyed that. Bollox all the same though. I don't even get bubbles.

Also, why would it not leach out of running water constantly? And if it happen's over time, why do you say it's worse on new hose?

Hmm, should I reply to someone who just says "it's bollox all the same"?  Ok, here goes.

It takes time for anything to leach out of the hose.  The OP mentions it occurs "first clean of the day".   I notice it a lot more after a long weekend off.  So, while it's leaching all the time, the concentration will build up overnight in the water stuck in the hose to the point where the effect is visible.  When the water's flowing the concentration probably doesn't get high enough.

As regards the new hose effect I suspect (only suspect) that over time there are fewer and fewer phthlate molecules left in the surface of the plastic and able to leach over into the water.

You might not get bubbles because of the material used in your hose.  I'm talking about Gardiners Microbore; other hoses might just not release the surfactants.  You might also not see it as much as me because I only clean three days a week, so there's a four day weekend for the concentration to build up.  (I see an astounding amount when I use the second reel in my van, which I use once a week just to be sure the second pump's not seizing up).

Ok, fair enough. I can see there may be at least some merit in what you say and take back my your a bampot statement.

It may well still be bollox though.

The thing that never ceases to amaze me on this forum isn't the lack of intelligence, it is after all a forum for windowcleaners, it is the total inability to tolerate the knowledge or opinion of others in the face of overwhelming logic and evidence.
