The bottles were a little dirty when I got them, but the formula works great!

Nothing cleans glass or metal as well as this cleaner. Been using for 20 yrs and just works

For those of you with glass pipes, this works. Definitely get it.

. 4-20 is a great product. Cleans glass stains away with some simple shaking. You won't regret this product. All organic and even smells good. A great value. We use it to clean our lab glass and it just sparkles when done. A little rinse and done. Just try it....you won't be disappointed.

Muy buen producto. Mi proceso: pongo la pipa en una bolsa ziplo y le coloco el producto (realmente poco) y lo dejo actuando unos 5 minutos en lo que pongo a hervir agua. Ya que el agua está, aguito la pipa con el producto y después vierto el agua caliente en la bolsa y lo agitó también. El producto limpia bastante bien pero si se necesita el agua caliente para que quede totalmente limpia, como nueva

I wanted to surprise my partner by cleaning his bong. As someone who does not partake, I did not know the first thing. 99% isopropyl and salt worked pretty well but for the life of me I could NOT get the hard to reach areas under those little "nubs" and it was making me CRAZY. This stuff is INCREDIBLE. Took mere minutes of light "shaking" and the bong, stem, and bowl look brand new! The smell reminds me a bit of blue icee but does make me a touch nauseous. *the bottle did seem to leak and lost a lot of liquid in shipping despite the seal sticker still appearing in tact. It did teach me a valuable lesson in crystals to liquid ratio & a little goes a LONG way. *For other newbs like me, the salt (if using iso)/crystals/grit does the heavy lifting, particularly in hard to reach areas. Regardless of the lesson learned, I don't think I would go back to the iso method because this was so quick, effective, and affordable. This formula also claims to be "non-toxic, biodegradable, and safe for glass, ceramic, and metal" (tho the ingredient list is not available and their website has an asterisk beside the words "non-toxic*"?) I will absolutely buy this again.

I have never had such an easy time cleaning my accessories.

Muy buena mezcla para limpiar cristales de manera rapida

Everything was delivered fast and on time. The 420 is clearly a high quality product with a nice smell and good ingredients. I do though believe it requires some practice the totally perfect the cleaning process as so far there is still some resin remaining.
