I wonder at vaseline - it is petroleum based and as a petrol product has the potential to dry skin...

As with the other women here, I recommend a sports designed anti-chafe cream. I use something called "3B action cream" but only find I need to put it on if I am going to be more than an hour and a quarter on a bike...

I am not sure how well vaseline washes out of Chamois and other bike pads, but when I used it on my babies' bottoms it washed out fine in a med-hot wash.

If you are going to use vaseline, I suggest a zinc based cream used in conjunction... this you will find in baby sections at the supermarket or chemist. Look for Zinc and Castor Oil cream. When you get home from a ride, apply it as a salve to any sore, grazed or potentially infected or lumpy bits. The coolness feels great, the zinc has HUGE healing properties and it washes out well.

The other thing I recommend, particularly for anything that seems remotely infected or is def infected, is a dab of "tea tree oil". It is a great healthy/natural alternative with antiseptic/antibiotic properties for use on grazes, pimples, boils and other infections... It will sting slightly but will help with healing infection.

Good luck with the combination that suits you...
