The law from God is good. There isn't something wrong with it, the problem we have with it is that there are things wrong with us. Do you know that? You say things are all made clean, out of context, with claiming that expectation of Jesus needing to wash according to the ritual had basis in the law, that he wouldn't observe, so because you claim this I should speak of how people would be unclean, that would make any ritual to be clean then be made necessary according to the law from God. So then look at Leviticus 5. See these verses 2-13.
"Or if anyone touches any unclean thing, whether it is the carcass of an unclean animal, or the carcass of unclean livestock, or the carcass of unclean creeping things, and it is hidden from him, and he is unclean, then he shall be guilty. Or if he touches the uncleanness of man, whatever his uncleanness is with which he is unclean, and it is hidden from him; when he knows of it, then he shall be guilty. Or if anyone swears rashly with his lips to do evil or to do good—whatever it is that a man might utter rashly with an oath, and it is hidden from him—when he knows of it, then he will be guilty of one of these. It shall be, when he is guilty of one of these, he shall confess that in which he has sinned; and he shall bring his trespass offering to Yahweh for his sin which he has sinned: a female from the flock, a lamb or a goat, for a sin offering; and the priest shall make atonement for him concerning his sin. If he can’t afford a lamb, then he shall bring his trespass offering for that in which he has sinned, two turtledoves, or two young pigeons, to Yahweh; one for a sin offering, and the other for a burnt offering. He shall bring them to the priest, who shall first offer the one which is for the sin offering. He shall wring off its head from its neck, but shall not sever it completely. He shall sprinkle some of the blood of the sin offering on the side of the altar; and the rest of the blood shall be drained out at the base of the altar. It is a sin offering. He shall offer the second for a burnt offering, according to the ordinance; and the priest shall make atonement for him concerning his sin which he has sinned, and he shall be forgiven. But if he can’t afford two turtledoves or two young pigeons, then he shall bring as his offering for that in which he has sinned, one tenth of an ephah of fine flour for a sin offering. He shall put no oil on it, and he shall not put any frankincense on it, for it is a sin offering. He shall bring it to the priest, and the priest shall take his handful of it as the memorial portion, and burn it on the altar, on the offerings of Yahweh made by fire. It is a sin offering. The priest shall make atonement for him concerning his sin that he has sinned in any of these things, and he will be forgiven; and the rest shall be the priest’s, as the meal offering."
Do you do these things? Do you know anyone at all who does these things? You and all others you know are otherwise unclean according to this standard, from the law from God. But through Christ who fulfills these things that we can't still do, we are made clean in the effective way before God. Christ is the only way for us in this, others all remain effectively unclean before God.
Had Jesus Christ been unclean that he needed ritual washing according to the law, it would have been from whatever made him unclean and he would have to do much more than the traditional ritual from the Pharisees, who used their traditions as if those were the law from God.
Again, when Jesus Christ said that it will be all clean for you it was in the context specifically shown where Pharisees who were present right then expected their ritual washing to be observed. Jesus had an issue specifically with that and was not changing commandments from God in front of those he criticized for putting traditions in the place of commandments from God. There is only the one understanding from it that is actually sensible with this context.
