Cleaning rounded corners

[DCartagena]

I think those green scrub pads on dish sponges work well for me and razor blades on my Corner Unit. just need to be careful with the razor blades since they can rust.

I had a 30g acrylic with rounded corners and used a toothbrush on the corners. After about 6months of doing it, I noticed one day the corners were slightly hazed. Drained it down a tad and noticed TONS of VERY fine scratching. They can be taken out rather easy just a pain in the bum since it was the corners.

i cut a small piece of filter pad. does a pretty good job without scratching the glass.
