Base cleaner is cheap. Lemonade is not a good cleaner. Diluted Dawn or any citrus cleaner will work.
And base cleaner will not dry up your base or mess wax absorption. What base cleaner does is remove ALL the wax from youe base. So you will have to throughly wax the board after using base cleaner. Hot scraping will remove some dirt and still keep wax in. But it won't completely remove dirt or old wax (which may matter if you are a racer using expensive, condition specific wax)
