Washing before washing before bread

Hi,

The rule for netilat yadayim is that one may not have a chatzitzah, an interruption, between his hands and the water. Therefore, one may need to wash his hands for cleanliness before washing ritually.

"Chatzitzah," for this purpose, is defined as one of two things:
a) A foreign material that covers the majority of the hand's surface area, or

b) A foreign material that covers any part of the hand's surface area, and is something which people ordinarily remove.

(Mishneh Berurah 161:1)

Have a great day,
Mordechai
