- clean all the part completely and thoroughly

- have acetic acid or any mild acid else

- the acetic acid must at a level 41-50 % concentrate

I would have to caution against 41-50% strength of actual acetic acid which is not very mild.

Perhaps you mean 41-50% common white vinegar.

The table vinegar itself is watered down acetic acid. Diluting that to about half-strength might still cause some skin sensitivity if it gets on the foot, but 40+% acetic acid is almost 10 times the strength of 50% vinegar and quite agressive & irritating.
