What should I replace first if I want the biggest impact?
Short answer
The things you use most often and throw away fastest — cleaning products, laundry, personal-care consumables — because the switch compounds every week. Replacing a working item purely to buy an ethical version usually creates more impact than it saves; wait until it needs replacing.
The detail
Frequency beats symbolism. A refillable hand soap used daily by four people displaces far more packaging over a year than a bamboo toothbrush, even though the toothbrush is the more recognisable swap.
The second lever is the highest-footprint purchases you make anyway: clothing, furniture, appliances. Choosing durable and repairable there matters more than perfecting the small consumables.
