So I’ve known about this stuff for as long as I’ve been dabbing (roughly a decade) but always thought it was overpriced nonsense. 

I’m relatively new to the switch 2, had it under a month, and have abused the sapphire plus a little too much especially over the 4th of july weekend. It took my so long to get the temp and time down I was definitely burning some dabs slightly while messing with it. This lead to a decent amount of staining that alcohol simply would not dent at all even after many hours in very warm alcohol with loads of agitation.

I decided to finally try DC as ive heard it can work good at restoring bangers and WOW did it ever. I left it soaking on a hot plate for about 24 hours and had to swab it aggressively about 7 times but I got 99.95% of the staining out. Would’ve been a lot faster and easier with an ultra sonic cleaner I think, I ordered one after proving to myself that this stuff works great.

It also got a decent size brown stain out of my quartz one from the first and only session I had on it where I burnt the dab in and alcohol couldn’t remove it. 

Have also used it to go to town on all my carta atomizers and they look brand new, didn’t think it was possible. Absolutely crazy stuff, not an advertisement btw just a customer who’s blown away and mad he hasn’t been buying this stuff… easy to filter and reuse as well. 10/10

Doubted it for 10 years but dark crystal glass cleaner is the truth..
