Sometimes it can be difficult to clean the insides of containers like vases and fish tanks. Many flower vases have an opening that is too narrow to fit your hand through and a shape that makes it inconvenient to use a brush. With a fish tank, you often have to drain the tank in order to clean the glass. Both of these problems can easily be solved with a simple magnetic scrubber. All you have to do is embed a strong magnet inside a sponge or other scrubbing tool. Then you can guide it with another magnet on the outside and clean even the most difficult to reach places.

Step 1: Select a Scrubbing Tool

The first thing that you need is a scrubbing tool. The ideal thing to use is a sponge. Since the magnetic scrubber that we are making is reversible, you can use a sponge with a course scrubber pad on one side and switch between the two sides as needed. You can also use tools like a magic eraser but these will degrade much faster than a sponge.
Great idea. This will be absolutely perfect for those of us that hate cleaning our hard to reach rear windows in our vehicles.
Excellent use case!!
Just be sure to use really strong magnets so that they stay attached.
With a little modification, you could glue the outside scrubber to a short dowel, the use an electric screwdriver to make it spin while you clean. You might need square magnets though.
<p>Wow Great Idea</p>
<p><em><strong>Good Idea !!!</strong></em></p>
<p>be careful what you use if you have an acrylic tank! use only approved products or you'll end up with scratches! (ps.. don't drain your tank to clean it either!! you'll lose too much of your good bacteria!)</p>
<p>Omg...excellent idea...on a larger scale, for cleaning older sliding windows, also.</p><p>...thanks for sharing !</p>
For a much larger scale, you can use a commercial magnetic scrubber. They are sold in pet stores to clean large fish tanks
I have a friend that has this on her fish tank it really helps n it work <br>
Cool but I am lazy and bought one perhaps you could do a mod on how to stop the magnets from picking up the fish stones and scratching the tank :)
Do you know that you posted this in a pet contest?
The idea was that it can be used for fish tanks and other animal cages. They accepted the entry so they think it is at least somewhat relevant.
<p>Genius!!! :) :) :)<br>I wonder if upsizing this would help to wash windows more easily - both sides at once and without climbing out there. I'll try it this spring.</p>
You just need to make sure that the magnets are strong enough. Most windows are pretty thick.
<p>this is so cool </p>
<p>Awesome idea, market it before someone else does!</p>
<p>As a lover of magnets and cleverness, this is one of those instructables that makes it worth visiting the site regularly and looking for ideas. THANKS!</p>
pure genius! I love it!!
Absolutely Brilliant! I cant wait to try this. I have a few hard drive magnets laying around.
<p>It's one of those d'oh-why-didn't-I-think-of-that-before idea. Thanks for this hack...</p>
<p>brilliant!!! thank you!</p>
