Well, I have tons of it on my 10g too, so don't feel bad. you can
get a sponge and warm water and scrub, or, you can do like i did and get a product called

Aquarium Pharmaceuticals Safe & Easy Aquarium Cleaner. It works great. I strongly reccomend you getting it. So easy to use, and doesn't harm your fish.

HTH
 
I have used Safe and Easy, but I have also used a brand called Seri Clean. They both worked really well.
 
salt use?

I'm wondering if some of it may be salt build-up? Are you using salt?
 
hard water

AAaah,
the stains and build up from hard water is a pain to clean.. Scraping seems safest. Never tried AP Safe and Easy; sounds good though.
