My advice is listning to Quran and tying to read it is in the bakc of your head whatever you have learned when you was a kid is still there..
another thing Visit to Arabic websites more often .. and Listen to Arabic islamic lectures really I know people who know Arabic now within 3 month just by listening to islamic lectures
