Last Week`s Question:
When we clean up the table on Shabbos we put the dishes straight into the dishwasher so as to avoid having them piling up in the sink.
Would it be ok to rinse off the dishes before putting them in the dishwasher so as to avoid having to do this on Motzai Shabbos or would this be an issue of Hachanah (preparing for after Shabbos on Shabbos)?
Answer: This case is subject to a dispute between R’ Feinstein and R’ Aurbach (Shmiras Shabbos K’hilchasah ch.28), whether pre soaking a pot (i.e. crock pot that was used for Cholent), to prevent the leftover food from hardening and becoming more difficult to clean is considered Hachanah.
According to R’ Feinstein being that the pot will only be cleaned after Shabbos, soaking it is preparing for after Shabbos and is therefore prohibited.
According to R’ Aurbach Hachanah is specifically when you are simply using Shabbos as a time to prepare for the coming week. Here, however, the reason that your soaking the pot now is not merely to prepare, rather your actively preventing a situation from developing (i.e. the food from hardening and becoming more difficult to clean) on Shabbos, and that is not considered Hachanah.
However this leniency would only apply if the pot is soaked immediately, so that the food has not already hardened. Whereas once the food has already hardened it would be considered Hachanah.
Another reason to allow rinsing the dish would be based off another ruling of R` Aurbach that an act which one normally does without giving thought as to when the outcome will be relevant is not subject to Hachanah. For example, taking one`s Talis home from Shul even though it won`t be needed until Sunday morning would be permitted on this principle.
One could argue that the same would apply in our case as well, being that it`s common practice to rinse a dish before placing it in the dishwasher without giving thought as to when you plan on washing it.
In practice, the ruling of Rabbi Fuerst is that it is prohibited due to Hachanah, and the ruling of Rabbi Zuker is that one who wishes to be lenient has what to rely upon.
This Week`s Question:
Can I feed my dog pet food which contains milk and meat or is that considered deriving benefit and therefore prohibited?
