I’m disgusted by those big reusable toilet brushes. I‘ve been using the Scrubbing Bubbles “Fresh Brush“ Heavy Duty brushes and Flushable Touch Ups for many years, and for me it’s the only good way I’ve found to stay up on cleaning the toilet as it’s easy and more sanitary. Instead of a big toilet brush, a thin handle hooks on the side of the bowl and is barely visible. I use the flushable Touch Ups regularly to keep the bowl fresh, but I use these Heavy Duty refills (usually a few times a month) whenever I start to get a ring or any visible buildup the touch ups can’t remove thoroughly.These disposable Heavy Duty brush refills are so easy to use. I just click the plastic part onto my wand and give the bowl a scrub for a couple minutes. These are like stiff sponges with cleaner in them and are more abrasive than the touch ups. They work so well I never have an excuse for a dirty toilet bowl, and it never gets very dirty as I don’t dread cleaning and it’s so easy to keep up. When done, I simply press the button on the wand to release the used Heavy Duty scrubber into the trash. I flush the toilet, plunge the wand in the toilet bowl with fresh water for a quick rinse and hang it to dry on a hook that attaches to the side of the toilet tank.My hands don’t even get dirty (though I still wash after), and there’s no strong smell. It’s so convenient to clean the bowl using these brushes and the flushable touch ups, so my toilet never looks gross and cleaning it never becomes a big deal. These refills have become impossible to find at my local drugstores, and I have no idea why as it’s a great product. I’m really glad I can still find them on Amazon. I find the price reasonable ($15.35 for a 2 pack w/ a total of 16 Heavy Duty refills) for a supply that lasts me about 6 months. These are the best, with the only downside being the inability to find them in person. Great product. 5 stars.PS: The reusable wand and touch ups are sold separately. I have a wand in each bathroom and have been using the same wands for at least 6 years (or more).
