Task: Question Answering
Input (English): One day I went into my bathroom to take a shower. There was a lot of gunk on the walls and hard water build up around the shower head. I decided it was time to clean the shower before things got worse. I went to my cleaning supply cabinet and took out some cleaning spray, paper towels, and a scrubber. Before I removed any grime from the shower, I took out all of my shampoo, conditioner, and other items from the shower. Whatever was empty or I never used, I tossed out. From there I sprayed down the shower with the cleaning chemicals and let it sit for a while. After that I got in there with the scrubber and scrubbed until there was nothing left on the tiles. On the more delicate things, I used the paper towels to wipe down. Once all was clean, I used the removable shower head to rinse down the shower walls and tub. Once clean, I returned the remaining shampoo bottles, etc. and put away my cleaning supplies.
Output (English): What kind of brush did they use to clean the shower walls?
