Hi guys i've recently brought a second hand water tank for the van.
I was all excited about using it.
I've used it for the first time today and the water was coming out all bubbling. I thought maybe it was the pressure. But tryed it on my own windows and it dried with white streaks all over it
Obviously it must of been cleaned out with some kind of detergent, How do i clean it out so it will be ok to use
Also i found out it took me longer to use than pure freedom trolley as hose kept catching on everything . Will this get easier in time?

Fill it up with tap water and let it run through a couple of times.

You don't need to fill it up!

The stuff, whatever it is, is on the walls, not in the space in the middle. Therefore, you only need to wash the walls.

Take it out of the van and into your garden where you can manipulate it.

Chuck in a bucket full of really hot water and slosh it about to wash all the walls including the top. Repeat this several times. You might need ten or twenty buckets full of water - about the same as you'd use in a deep, luxuriant bath!

This is probably faster as you can be sloshing one bucketful around whilst the next bucket is filling from the tap. You'll get the entire job done in less time than it requires to just fill the tank once!

stick a garden sprinkler in it

I'd chuck 25lts of pure in and swill it all around then tip it out, check some with a tds meter and repeat till it comes back out at what it went in, ie 000tds then it's clean.

[Mr Sparkle]

The thing what i can't understand is it was coming out at 0.00tds.
would fairy liquid etc show up as high tds?
I'm so confused, don't want to go back to lugging trolley and 25litre barrels out of van again

fill with water till you cannot see the bottom of the tank

turn tank around a few times

empty

Might be a silly question but..... is it a dedicated water tank for window cleaning or is it one of those IBC containers?

I had trouble with an IBC that I use as a static tank in my garden. It had had that 'adblue' solution in it that the trucks use nowadays to reduce exhaust emmisions. Basically 'adblue' is synthetic urea and causes all sorts of problems. If your tank/container has had this in it, you've got issues. Best option is fairy liquid and a brush on a stick, hottest water you can get and really give it the nasty on all surfaces inside. Then copious ammount of rinsing. If you can wait till it's raining, use your down pipe from your roof. Surprising how fast it will fill up!

Again, this is just a little of my experience. It might help you, it might not.

fill up with tfr and hot water to the top and leave over night and wash out 3/4 times in the morning that should work.
