You could use the gripcovers over them that unimax sells but the t-tech do not back seal like the hawks. So I would soak the grips in madacide over night at least.The health dept. in my area accepted that(Althoe I do have an autoclave I want to find a quicker way,if they become soiled then they must be autoclave etc.).So first a wipe down then a min. of a 8hour soak. in a clean container marked just for that(which also must be wiped down and kept clean at all times).Then then they have to be stored in a marked "madacide soaked" pouch & dated then stored in a clean container much like you would do with a autoclave setup.Also you must keep on file when/were the madacide was bought and also keep it clean(lid area etc.)and stored properly.
