The structure is:
捐赠以前 + 要 + 先 + 消毒
A very literal breakdown is:
- 捐赠以前 = before donating / before the donation
- 要 = need to / must
- 先 = first
- 消毒 = disinfect / sterilize / sanitize
So the sentence follows a common Chinese pattern:
time phrase + modal verb + sequence word + main verb
In natural English, it comes out as something like:
Before donating, you need to disinfect first.
The word order feels different from English, but it is very normal in Chinese to put the time phrase near the beginning.
