## 最终结论
```python
import re

def remove(strings):
    result = []
    for string in strings:
        # 使用正则表达式去除所有数字
        cleaned_string = re.sub(r'\d+', '', string)
        result.append(cleaned_string)
    return result

# Test cases
assert remove(['4words', '3letters', '4digits']) == ['words', 'letters', 'digits']
assert remove(['28Jan','12Jan','11Jan']) == ['Jan','Jan','Jan']
assert remove(['wonder1','wonder2','wonder3']) == ['wonder','wonder','wonder']
```
