When to wash baby bottles and breast pump before delivery

Hi all. First time mom here, currently at wk37+1 and nesting for the arrival of baby. Would like to hear your advice when to start washing milk bottles and breast pump? I won’t be bringing them to the hospital and also, my husband is probably gonna stay at the hosp throughout with me during delivery. Hence want to avoid the hassle of asking him to come home just to wash bottles. Just wondering how best to keep them sterilize if wash them early now (my haenim uv sterilizer can’t fit everything inside). Welcome any suggestion. Thank you!
