Cleaning Second hand Acrylic Tank

[wonderphil-reef]

Question for everyone, I just brought a second-hand Acrylic tank, wasn't brought from an LFS, and I was told it had big scratches inside, and they have polished them out.

I am worried about what was used to do the cut & polish, so what is the best thing I can use to clean the inside of the tank to make it fish safe?

Water and a soft cloth if you wipe it down. There isn't much to worry about ime.

I’ve used Dawn Dish Detergent, to get 3M Plastic Polish Residue Cleaned up. Works well and the Dawn rinses out with Lukewarm water.
