Can you wash your hands completely after Chatzos on Tisha B'Av?

Question

One of the restrictions of Tisha B'Av is to only wash your hands until the knuckles. Is this restriction relaxed after Chatzos on Tisha B'Av? (sources please)

Answer 1

Rabbi Shimon Eider in his "Summary of the Halochos of the Three Weeks" Lakewood, 5738 - 1978, says that washing, amongst other issurim, is prohibited the whole day (section V, G, 5). Only sitting on a bench above three tefachim, smoking, and work are allowed after noon (see in the sefer for details about work) and of course CYLOR.

Answer 2

The 5 Inuyim (afflictions: eating & drinking, washing, etc.) are Rabbinically prohibited the whole day. There are other customs, such as not sitting on a chair, etc. and these are only customary until noon.
