Dave, Tropica Mastergrow is a one part formulation and there shouldn't be anything in it which would hurt you unless your skin is very sensitive. Either a damp towel or a quick run under the tap should be enough to get the residual off of the outside of the bottles. James P.S...... welcome to the joys of International Shipping..... I once got a box of Duplarit G which was so mangled in shipping that there was even red dust imbedded in the adhesive of the tape covering the outside of the package. ------------------ To unsubscribe from this list, e-mail majordomo@thekrib.com with "unsubscribe aga-contest" in the body of the message.
