Not sure about All Clear but some of the tank cleaners can create a lot of foam when added to the rinse water.Any idea why/how foam would get into rinse tank from solution tank? Not sure if it happened last time I rinsed with all clear or while spraying Liberty/Centurion.
Wanted to top up rinse tank so I could flush booms on last field and it overflowed with foamy stuff.Just wondering how you found out it has foam in it? Did you just happen to look in it? On my 4930 the lid for the rinse tank is on right hand side of cab and need a ladder to get to it so the only time I open the lid is at the end of season to put antifreeze in it.
