grrr. blinkin milky white run off still happening even after windows have been done several times before. can it just keep happening? or should it eventually stop? as i feel bad having to explain it to the customer. Of course, this never happens with pvc frames, but many of you will know of this issue with old painted wooden framed windows. Does rinsing even more help? or is it just something that will keep happening. Proper pain I know that.
