We use Marigolds which we change every week.
I find that these and the other heavy duty gloves even though they are size small are still too large to pick up some instruments.
Hello kcp,
It states in the HTM 01-05, that they should be changed every week or more often if needed.
If you want to check it out, there are now Pink heavy duty gloves to use as well!
Even latex free heavy duty gloves!
