Limud Torah

SEIF 10
The Maharam did not wipe his hands on a towel until he removed most of the water from them by vigorously flaying his hands. He was worried that an excess of water would result with transgressing the Issur of laundering the towel on Shabbos. The Mechaber concludes that it is a good thing to keep this Chumra. The Rama says there is no reason to keep it, for even if there is some excess water which gets on the towel, it is only done in a manner which will make the towel dirtier.
