No risk. HIV can't be transmitted once it is seperated from it's host, once in contact with external environment the virus becomes inactive.
Please read about HIV and it's transmission:

I assure you that your child is safe and this incident doesn't posses any risk.
As stated very clearly and accurately, this is not a risk for HIV. We are now closing this discussion and wish you the best.
