if emulsion remover wont wash it all out then the pressure washer has always worked for me.
your attachment may still not be enough pressure to get the spots out. I used to use hose attachment that would work for most parts but still leave spots behind. I got a 1800 psi pressure washer and it will get all the spots out that the attachment couldnt.I am sorry I did fail to mention I do have an attachment for my water hose and it does have high pressure settings. So it looks like dehaze is going to be my only option.. I sure do wish I could find a cheap and easy solution. Maybe just gonna have to get a re-screening.
