I'm a gfe provider and yes cleanliness makes a big difference in my comfort level.  If I'm not liking the smell or there is too much hair in the way I don't focus as well. I always try to be aware of my hygiene with showers/baths and yes the wet wipes are a must.  

I wonder if I should mention it my client or maybe just offerring to take a shower with them would suffice.  If it is a habit of a client to have poor hygiene each time we meet I usually won't see them again.  

We make sure our utensils (forks, spoons etc.)are clean before we put them in our mouth so it would be a common courteous to make sure our personal utensils are properly santized as well.
