STD risk

hello dr tan
today I unaccidentally stabb a syringe for a printer ink into my finger when I washed it with dish soap (3x washed with dish soap) I was stabb after washing the third times, the syringe already use for printer before, then not used for 1 year, I do not know if the syringe is new or used in the past because it is bringing the employees of a shop, I also do not know the syringe unaccidentally already stabb into the hands of the employee before or not, I also do not know the employee they have hiv, hbv, hcv or not,i dont know is there blood stain or not before use for printer syringe.cause the syringe for medical use and it is used for printer ink,not specialized syringe for printer ink

my question

1) am I at risk of contracting the hiv/hbv/hcv or other kind of virus/bacteria?
2) if yes what kind of test which i should take?
3) if yes and how many days/month after puncture syringe i should test?

thank you and sorry for my bad english
