Use a soft bristled brush to gently scrub areas. Heavy deposits can be scraped gently with the edge of a spoon. If you can treat the water, that may prevent deposits. A bit of algae growth may also "soften" the water as will powerful filtration. A filter rated for 3-4 times the volume of the tank may remove enough minerals to decrease accumulations.
