Powerful Cleaning Tool for Delicate Surfaces

Do you sometimes have heavily soiled surfaces? So heavily soiled that you would prefer to sand them down? But you can't do that, because some surfaces are very sensitive. Such as baking trays or tiles.

Scrubbing!

That requires a lot of scrubbing. Exhausting, time-consuming. But there are tools for that. Oscillating tools. And we are now going to convert one of them.

1. 1x 3D printed part
2. An oscillating tool, often called a multi-tool, available at hardware stores. Here: BOSCH PMF 220 CE
3. Big metal clip for papers, approximately 8-10 cm wide
4. Large screw with nut, 8 mm
5. Protective cover for metal clamp, 3D printing or heat-shrink tubing, liquid latex

1. Schwamm
2. Edelstahl-Schwamm

Most electric multi-tools have their own tool holder. The popular multi-tool from BOSCH, "PMF 220 CE", has a star-shaped holder. Tools for sawing and grinding are generally available in stores, but tools for cleaning or holding an object are not.

I imitated the BOSCH holder using Tinkercad.com. It can be attached at many angles using a screw.

I printed the newly designed bracket with a 3-layer wall and 12 percent infill in PLA. It worked perfectly for the initial tests.

The metal clamp is attached to one arm of our new bracket with a screw. I used a self-locking nut for this because of the strong vibrations of the device.

To prevent our delicate surfaces from being scratched by the metal clamp, they are given additional protection. This can also be 3D printed, but abrasion-resistant hoses or liquid latex could also be used here.

The plastic splints are fixed in place with strong all-purpose glue. Superglue would also work.

Now for cleaning.

If available in your country, use stainless steel cleaning sponges, not steel wool! You can also clamp any other sponge into the clamp, but it should hang well over the metal clamp.

Water, soap, or a mild abrasive cleaner—let's get started!

Set your multi-tool to the lowest setting.

Important:

Do NOT press down hard when cleaning! Cleaning is achieved through numerous rapid back-and-forth movements. Simply hold the device steady, nothing more.
