I use a soft toothbrush and scrub it a little bit.

I use a old gift card or credit card with smooth edges to scrape of the hard algae on my acrylic tank.

i would go with a new toothbrush, i have an acrylic biorb,and the algae cleaner that reef one sell for that does quite a bit of damage(surface scratches), def dont use a magna float, that is way too rough,or maybe the credit card will be ok but i havent tried that one.
