Update on my glasses, soaked all glasses in 1lt vinegar and 4 lt water, rinsed under near boiling water, result slight improvement on head and bubbles, but not much.
Am going to try the caustic soda route with a couple of glasses, if that doesn't work I might have to throw out the old and in with the new.
No, wait, I really shouldn't talk about my lovely wife like that!!!! :lol: .
Can you beleive that after all my complaining about the evils of rinse aid, I look in the dishwasher and she has filled up the dispenser AGAIN. :angry: <_< .
