cleaning light fixture glass

[Delphinus]

I use muriatic acid on some things too and did use it to clean my halide glass a couple times (heavily diluted) but even diluted the stuff is nasty to work with. It hurts to breathe that stuff, so ventilation is something of a must, and disposable work gloves also a good idea because if you have any kind of cuts or scratches on your fingers and you get it into that, it's an unpleasant time. With that said though, man that stuff makes cleanup an easy breezey 1-2-3 kind of task. Like Tim said: "acid into water, not water into acid".

I've always just used water and a sponge, its tricky to get it all off, but I think the trick is to clean it, let it dry, clean the sponge or towel, use clean water/vinegar, repeat as necessary. even with my FW tank with no salt, I still get build up of sorts, and its tough to get it perfect

Agreed on the acid. Well diluted, well ventilated, well protected and neutralize after use with baking soda.
