Reddit reviews Enforcer ZUCIT128 128-Ounce Zep Heavy-Duty Citrus Degreaser Refill (packaging may vary)

Zep citrus degreaser, get yourself a glass on glass plug, fill up your tube to the top with degreaser and let it sit for 20 minutes to an hour depending on how dirty it is then pour the degreaser back into the bottle and wash your glass out thoroughly.

I prefer this over salt and iso because I don't really like the idea of shaking my glass around, also if you have a lot of glass it's really easy to clean a lot of stuff at once.

The only things you can do to keep your piece from getting dirty in the first place are A) vaporize and B) use an ashcatcher. Neither is perfect, but vaping will keep your piece way cleaner. An ashcatcher will do exactly as it implies, catch ash, but you still will need to regularly change your water.

Spiral percs, tree percs, diffusion percs, they're all going to (eventually) get dirty.

As for cheapest cleaning method; I've used iso+salt with great success, but due to laziness and the generosity of a frient, I switched to GrungeOff. However, that shit is expensive, so most recently I've purchased a gallon of citrus degreaser from Home Depot for about $12. Fill your piece with it, let it sit overnight, strain the degreaser through a coffee filter so you can reuse it, and then rinse your piece out thoroughly before using it.

And I've never heard of Mozone. Pic?

[Look for this] (https://www.amazon.com/ZUCIT128-128-Ounce-Zep-Heavy-Duty-Degreaser/dp/B001B1AIM2/ref=sr_1_6?ie=UTF8&qid=1538152698&sr=8-6&keywords=orange+cleaner+degreaser) at a lowes, home depot or Menards type store. 10-15 bucks for a gallon that'll last for a year or more if you only use it to clean pipes. I keep a small dish by my slop sink and just hot rinse and dip my pipe every other day, keeps it looking mint with next to no effort.

It probably is oranges. Citrus degreasers work great and are much safer than many alternatives - both for you and the materials you're cleaning. If you're doing this sort of stuff a lot, it's going to be a lot cheaper to buy essentially the same stuff in gallon jugs instead of 30ml bottles.
