nope if you had other stuff in there then that wouldnt be a good idea but just wash it by hand or whatever.
No but you dont have to. All you need to do is fill it up with some water, add washing powder, put a stopper if it has a carb hole and shake it well. Let it sit for a while and then rinse it. You will immediately notice the water is a little brownish and cloudy, repeat if you want to really get off that residue. EDIT: Use warm water btw.
Negative ghost rider. Don't use soap or washing powder. Use Iso, Grung Off, or Simple green to do your cleaning.
Really? I saw a video once, using this method and it cleaned it really well. What is Iso/Grung Off/Simple green? I'm not saying I'm right, I'm just curious. I guess its because for some plastic bongs it can damage it? Enlighten me please
ISO = rubbing alcohol try to get the %91. Grunge off is hands down the best glass cleaner out there. You soak your shit in it and comes out sparkling. Simple green is a biodegradable cleaner that they sell at walmart and such stores and is like grunge off on a budget. I use to use it untill I bought Grunge Off. There is a whole thread on cleaning your glass. http://forum.grasscity.com/toking-tools/235580-official-piece-cleaning-guide.html
dishwasher plus glass bong can equal broken bong... I have seen it happen before just stick to hand washing
