1. you can easily build a blasting cabinet with wood & plexiglass for cheap - not saying it will last a long time but you don't need it to

2. cost to take it somewhere??

3. soaking - how safe is oven cleaner on Al? might worry me

4. buy the special impregnated 3M things for that die grinder - they work a LOT better than a chunk of scrubby that you try to chuck up and spin at high speed

5. your wife's dishwasher will do an amazing job - she will be delighted if you give her a gift certificate for a special 3 hour shopping spree at her favorite store; tell her it is "just because"
