I tried to clean a small silicone bubbler using the 8 fl. Oz bag. Perhaps it was my fault for not purchasing the larger size but I truly didn’t believe I needed it. The bubbler wasn’t completely submerged but certainly enough to get the job done. I followed the instructions and let all of my items soak in hot water inside of the bag, probably for a good 11 hours. While it sorta polished up my piece and bowl, it wasn’t great and not a big improvement over hand cleaning myself. All in all worth a go and honestly, this is still pretty convenient. I just wasn’t all that thrilled about the end result.
