420 Science RezBlock Concentrate Resin Preventer, 30ml (30ml)

I got this for my Dr. Dabber Switch's percolators. I love my switch but since I use dabs for medicinal reasons I kept trying to find a way to stop any of that wax resin build up from getting in the percolator or clogging it up as it had done many times. I tried this out and it works wonderfully! it eventually gets some build up(easier to clean too)but I find I don't have to constantly change the water or 'deep clean' the quartz percolator nearly daily. It has made cleaning it much easier on me, which is a huge help for me. I don't have to use much of it but the switch uses very little water. I would STRONGLY recommend this stuff to anyone looking to use it on a quartz rig, part of a dab rig or on your own Dr. Dabber!Also I've had new quartz have all the resin stick to it badly, I tried doing a quick rinse of this stuff and using it in new quartz and did not have any of the issue!! Great for Dabbing!

Works like a charm! No funky smells or taste.

As most of the other reviews like reiterate, I will again, THIS IS NOT A CLEANING PRODUCT!!!!However this is an AMAZING product to MAINTAIN a clean bong!!! Regular smoking causes resin build up on the glass, which can then leave the smoker lacking the original "high" feeling they had with clean glass. This product keeps that resin from building up on any area that touches the water.That being said... if you look at the pictures above it does have a slight cleaning element to it. The glass was almost stained from use but after several water changes with the drops in it, it removed the stain! Also there is ABSOLUTELY NO flavor added during use of this product! It does add a slight red or pink hue to the water but no flavor. I will be recommending this product on a regular basis!

Its best on a new piece; to help it looking like new and keep it easy to clean. This stuff works pretty well. Use Kryptonite and clean out your piece if its dirty first. Kryptonite is the best cleaner I have ever used period. Its even reusable. No shaking or anything needed; just make sure it coats the glass. Let it sit for 30min and rinse it out with warm water. It pretty much dissolves anything in your piece. Now add in RezBlock and you will literally never have to clean it again. For the most part. Just a bit of warm water and it will rinse any resin out. That easy. Yes I said if you use this all right youll never have to clean but only rinse your piece.

I cannot say enough about this product. It makes cleaning your bong so easy.

This is the best stuff I have ever used! Great price and lasts a while as you only need to add a little bit to the water. Helps keep my pieces cleaner longer, and easier and less mess to clean up.

Perfect

Neither the product box or the bottle were sealed. The box had an indentation showing it was opened.The actual product works great, it's not a cleaner, it makes cleaning a lot easier. I tried using basic water and adding this blocker. It is a lot quicker and less hassle to clean when using the RezBlocker. I just need to find a good source for purchasing.
