Review on MR.SIGA Multi-Functional Eraser Sponge: 48 Count, Ideal for Kitchen & Household Cleaning by Gina Putnam

I bought these after watching a YouTube video about restoring old laptops. When they arrived, the first thing I tried out was the touchpad on my Dell XPS 13 systems. After just a few months, these touchpads look awful. The rest of the laptop can be covered in smudges, but the touchpads always look awful. It took about a minute to clean but the results were excellent and the surface looks brand new. Now I understand these cleaners work through very light abrasion so not something you want to do every day but the results are worth it. Another test involved chrome parts around some electronic parts. A cloudy film forms on them over time, which is not immediately removed by Windex and a microfiber cloth. Deleting them worked really well. Very light dust is generated during use. This is minimal when using water, but noticeable when cleaning black or dark colored items. A quick wipe with a damp cloth will remove this powder. Each sponge is sufficient for a sufficient amount of cleaning. I used half the sponge on several touchpads and it looked just as good afterwards. Cleaning the lid of a Lenovo laptop is a different story. This brought back the finish, but the sponge was black when finished. In general I am very happy with it.
