Question:
I put milky plastic bowl, that I hadn’t used in a long time, in meaty dishwasher what do I do?
Answer:
You can still use the bowl. The reason is because there are a number of lenient factors here, the fact that there is dishwashing soap which will make the water have a bad taste, secondly the water spraying on to the dish is iruy kli rishon, which only can impart a small amount of taste, together with the fact that any meaty residue from the other dishes would be nat-bar-nat. This does not mean that one should do this intentionally, however in retrospect, it the dish is still permitted to use.
Best wishes
