Also tried tonight the filtered water + joy mix.
Nawala yung gritiness ng wiper kapag nag sweep siya.
Also noticed na mas clear yung glass after, though sa una medyo malabo since nag bubula yung soap.

BTW i noticed na kapag matagal naka on yung washer spray, nag auto off siya?
Same goes for the rear one. Does it heat up that much ba? Pinalitan ko kasi nung umuulan kanina, so I am left to drain the reservoir via washer spray.
