Thread: Lemon juice in an ultrasonic cleaner

I was prepping another batch of brass the other night. I normally use white vinegar in the ultrasonic cleaner, but had run out of it. What I did have was plenty of lemons, so I thought I'd give lemon juice a go. Wow, it did a fantastic job. Juice of 2 lemons to about 2 cups of water and a drop of dishwashing liquid. Any issues with using it on brass regularly? I gave it a good rinse and then a soak in some bicarbonate of soda to neutralise any residual acid as I do for the vinegar solution.
