Hi all been having a few issues today with spotting on some glass mainly seems to be the ones in direct sunlight...I am very confused as ppm is 000 brushed twice and rinsed every window twice most were only little ones and you had to look close but were still there!! and ideas? and i have my pressure on 30 all the time so no splashing 

Many thanks

Different windows require different techniques. Need more info really.

What kind of window was it and where were the spots?

The only reason you get spotting is from contamination, it's a technique issue.

Whats the difference would splashing not be a issue? only prob is at 40 I seem to run out by 4!

Airborne dust particles sticking to you wet glass. You can't see it, but there is million's of it floating around all day every day, more so with a breeze and wind.

99.9999999999999999% of spotting is caused by this when the proper technique and equipment are used.

Not a science fact by the way, just the musing's of an old hand with many a wfp cleaned windy under his belt.

the main problematic one was leaded lights or whatever theyre called however do the niegbours exactly same house and no problems?! the other one was brown frames upvc normal glass just little tiny spots...

could it possibly also be caused by not rinsing close enough to the glass?

Where the spots? All over? Top 2 inches?

on the leaded once mainly just after the lead or sitting on top of it and with the plain glass dotted about no clues as to were theyd come from...I'm assuming must have just been technique but havnt had this problem in a very long time

Sounds like you need to rinse more to be honest.

There's also the chance it could be a mineral deposit on the glass that won't come off without a chemical.

How many rinses do you usually do? yeh i thought of that aswell some of the marks came off with a microfibre that was clearly light spotting the others wouldnt budge though

[Jonny 87]

Just one rinse off the glass.

Along the top line back and forward twice pretty slow. Then chase the water down. If it's hydrophobic glass make sure you take a bit longer to rinse.
