- The Ari z”l writes that one who is careful not to eat even a tiny bit of chometz on Pesach is guaranteed not to sin the entire year. (BaH1)
- Mid’oraysa, chometz on Pesach is like any other issur which would become bottul 1:60. However the Chachomim decreed that even a tiny bit of chometz that falls into Pesach food will make the entire mixture forbidden even to benefit from. The mixture must be burnt. (ShA — MB )
- There are ways to avoid a monetary loss if the loss will be substantial, or if there are many other mitigating factors. (MB , )
- Pots that have been used for chometz are allowed to be kept for after Pesach; just wash them clean before putting them away. (Rama — MB )
- The above chumra applies only when the mixture occurred from the onset of Yom Tov until after Shmini shel Pesach, when the issur of chometz becomes a chiyuv korais. If there is no issur korais, the Chachomim allow the chometz to become bottul according to regular rules of issur mixtures. This includes: (a) the mixture occurred before Yom Tov including after chatzos on erev Pesach; (b) the mixture was one of chometz nuksha; (c) the mixture was merely ta’am tifgam. (ShA — MB )
- Whenever you want to be machmir for a suspicion of a doubt of a bit of chometz, make sure you will not be wasting food. You can eat it if the food will not last until after Pesach. (MB )
- You may not eat on Pesach spicy food that was cut or chopped with a chometzdig knife, even if the knife was clean. If you know the knife was never used for hot chometz, then the food is permitted. (MB )
- Noodles are not chometz nukshe; they are chometz gomur. (ShA )
- Some people refrain from playing cards on the Pesach table because of the worry that maybe some bits of chometz nukshe from them will fall into the food. (Rama )
