The first Mishnah said that the Mizbeach (altar) sanctifies items that are fit for it. If an item is placed on the Mizbeach and is supposed to be there, even if it is invalid, it retains some level of Kedushah (sanctity). Here we’ll elaborate and say that it is not only the Mizbeach that sanctifies on a certain level; other parts of the Beit HaMikdash do as well. The Mishnah says that just as the Mizbeach sanctifies what is fit for it, the ramp of the Mizbeach also sanctifies items that are fit for it. If an invalid korban (offering), part of a korban, or something else was placed on the ramp of the Mizbeach, it has a certain level of sanctity and has to be put on the Mizbeach itself.
Just as the Mizbeach and the ramp sanctify items that are fit for them, likewise, the holy vessels, the Klei Sharet, also sanctify what is fit for them. If a person verbally designates something as a korban or as a gift to the Beit HaMikdash, it acquires a certain Kedushat Damim, monetary sanctity, and would not be allowed to be used for anything else unless it were properly redeemed. Only when it is put into a Klei Sharet, the holy vessels of the Beit HaMikdash, does it acquire a certain Kedushat haGuf, physical sanctity, which makes it a korban. At this point, you cannot redeem the korban, and it can also become disqualified by becoming Tameh (ritually impure) in some way.
So we’re learning from here that just as the Mizbeach and the ramp have the ability to sanctify a korban, the Klei Sharet also have the ability to do that. Even if it becomes invalid—for example, if invalid blood is placed in the Klei Sharet—it now becomes fit for Zerikah (sprinkling) on the Mizbeach. Vessels that were designated for liquids sanctify liquids. Measures that were designated for solids sanctify solids. Vessels that were designated for liquids do not sanctify solids, and measures that were designated for solids do not sanctify liquids. If you have sacred vessels that were punctured, if there is a hole in them, and they could still be used in a way similar to how they were used when whole, they sanctify what is put inside them. But if not—if they cannot be used in that same way because of the hole—they do not sanctify what is put inside them. All of these items sanctify only when they are in the courtyard of the Beit HaMikdash. If they are not in the courtyard of the Beit HaMikdash, they do not sanctify.
