The best thing you can do is base it out of solution then re-salt it... This is the easiest thing in the world once you get the jist of it. Coke, water, 10% ammonia, vinegar or another diluted acid that is strong enough to salt it, and a couple of glass beakers or shot glasses is all you need....
The thing about the acetone wash process is that you have to dehydrate the impure acetone of water before you do this...
A whole gram of coke can dissolve in a ml of water... So, if the acetone has not been dried, bye bye coke... You will have to let it evaporate and start all over...
Since freebased coke is practically insoluble in water, it will clump and collect on the bottom of the container... Collect it and rinse with a little fresh water, and drip the acid on them till it completely dissolves... Let it dry...
