Along side your alcohol, salt and rice you should try these 3 simple bong and pipe cleaning tools. Most of the work is going to be done by the aforementioned items, but these additional tools can help any situation.
My first go-to helper is the “q-tip” or cotton swab. These nifty tools are very safe for all of your glass especially. One of the best parts of Qtips is they are disposable. They are flexible and can make it into very tight spots also. Dip them in alcohol for added affect. I find Q-tips to be a valuable tool for not only cleaning, but they are great for maintaining. Again, dip them in alcohol and they work wonders. Remember that you can buy extra long versions too. This will aid the cleaning of larger pieces.
