Cleaning inside Acrylic Tank

[jon.dub]

What do you guys use to clean the inside of acrylic tank without scratching it? I bought Continuum AquaBlade P 24" Acrylic Safe Algae Scraper w/ Plastic Blade from amazon and i got novus 1 for the outside.
New to acrylic so any recommendations would help thank you!

Try Mr. Clean Magic Erasers. I asked when I visited Monterey Bay Aquarium a few months ago and this is what they use on their smaller tanks. They have worked well for me so far. One word of caution: with anything you use, you have to be extremely careful not to have even the smallest particle of sand, dirt or gravel trapped in the cleaning device or you will scratch your tank.
