What’s in it

  • A citrus and mineral-based formula made with orange peel extract that lift resin and tar. The brand lists “a citrus and mineral-based formula made with orange peel extract.”
  • Alcohol-free (confirmed by Green Piece; Amazon also lists “Alcohol Free”).
  • Fresh orange scent.
  • A biodegradable, “Earth Friendly” formula, made in the USA.

What it’s safe on

It is safe on glass, quartz, metal, plastic, silicone and ceramic pieces, including quartz bangers and water bubblers.

How long to soak

A few minutes of soaking is usually enough. For heavy, caked-on buildup, give it extra time; hot water speeds it up. A quick shake while it soaks and a brush on stubborn spots both help.

Pour it back

When you’re done, pour the used liquid back into the bottle and use it again. Reviewers say a bottle “lasts a long time.”

How to clean a bong with Green Piece

  1. Empty the old water and rinse the piece with warm water.
  2. Plug the openings with silicone plugs, or put small pieces in a sealed bag or jar.
  3. Fill with Green Piece until it covers the buildup.
  4. Let it soak. Most pieces come clean in a few minutes; for heavy, caked-on buildup, give it extra time, and hot water speeds it up. Shake now and then.
  5. Brush stubborn spots with a nylon tube brush.
  6. Pour the cleaner back into the bottle to use again.
  7. Rinse well with warm water (soap optional) and let it air dry.

Who wins where: Formula 420 (per its maker) and alcohol + salt are shake-and-rinse methods, so they need shaking. If you want an alcohol-free soak that’s easy on delicate percolators, Green Piece is a better fit. Both soak cleaners in the table are alcohol-free and quartz-safe.

Other uses (owner-confirmed)

The Green Piece team says customers also use the cleaner on the items below. These are uses the team has reported, not lab-tested claims. Always test on a small hidden spot first.

  • Jewelry. Test first on delicate or porous stones (pearl, opal, turquoise, for example) and on plated finishes.
  • Stains
