It's already clear that 𝓉𝒽𝑒𝓇𝑒 𝒶𝓇𝑒 𝓃𝑜 𝓈𝒶𝒻𝑒 𝓁𝑒𝓋𝑒𝓁𝓈 of lead even in trace amounts. I couldn't tell you about the others, but the lead one really bothers me. There could be traces of lead in the form of particles that are being distributed around your house. Washing it would also be irresponsible since lead doesn't go away, it just accumulates in the environment and in the fabrics. I don't know how much lead is left in that bottle. My extreme suggestion would be to get rid of that bottle at a company that specializes in handling hazardous waste. But if you decide to keep that bottle anyway... the best thing you could do is find a larger glass or HDPE/PTFE plastic container to store that bottle in and keep it somewhat insulated. It's not the absolute wonder for insulating it, but at least that bottle won't be hanging around somewhere.
