Cuisipro Magnetic Spot Scrubber, Black

I am a home brewer. When the scrubber arrived today, I had a carboy waiting on the counter. It worked really well, I was pleasantly surprised. The glass on that carboy is nearly 1/4" thick and has ridges, but no problem. I think if you had dried on goop it wouldn't work very well, but if you've been soaking it in hot soapy water the gunk comes off very easily. A bottle brush is better, but it can only reach so much. This will take care of what the brush doesn't. I am happy with this purchase!

the scrubbers are too big to fit into anything that would be hard to clean otherwise. useless and the magnetic effect was weak

This is a fantastic little cleaning gadget. I have cut myself a few times because of glasses breaking when I put my hand in and try to clean them. With this gadget, one does not have to do anything but move it around and it cleans glass, bottles, and metal items from the inside. I have not tried it on plastic as yet, but am assuming it works on plastic items as well since it's magnetic. I highly recommend, as does the friend who saw it work and bought one for herself.

We got this to clean out a glass iced tea container that we’re not able to clean because of the shape. The idea is great however either our stain was too permanent or the magnet wasn’t strong enough to clean it.

I purchased this scrubber for use with my glass wine decanter. It does easily fit down the neck of the decanter and the magnet is quite strong. I have no issues getting this product to work. Of course, it isn't as effective as a cloth for filmy residue and things like that, but I've found you can put a little piece of paper towel or washcloth under the scrubby pad to resolve that. It is small, so cleaning is tedious, but it works! I would just recommend rinsing anything you would need to use this scrubber to clean as soon as you are done using it and then cleaning it ASAP to avoid more challenging tacked-on grime.

WoW, this thing is great!! No moving parts to wear out. Does not use any power source. It will be there for years without wearing out. If you have non-metal things you want to wash, and your hands do not fit in? This is your answer. Just slide the small part into the glass (or in my case, plastic jug, and then you can use the outside part to reach where you can not.I bought 2 so that I am never without one, its that great for keeping things clean.

Saw this on a reel on social media and someone was using it to clean their fish bowl. I thought it would work but it doesn’t. Returning.

These awesome little gadgets work great for cleaning narrow mouthed vases and jugs, ect. I especially love how it gets my reusable water bottle all clean and fresh! Works well for SodaStream bottles also! I've been using mine for years. I got this one for my mother-in-law, who does a lot of canning and also distills all her water into large glass jugs.
