Q: Does a few miniscule grains of iron dust (grains are less that 0,5mm) affect the validity of the ghusl or wudhu? Such grains are mostly on ironware like housekeys or after doing some ironwork a few stay on the hands even after washing. You can notice them best if you hold your hands against the sunshine then you see them blinking. Few days after ghusl I notiticed few such miniscule iron grains, you can hardly notice them unless light falls on them so that they blink. The grains are less than 0,5 mm. Seems to me that they are kind of unavoidable especially when walking barefeet on floors etc.

Q: A person has relations with his wife with a cloth inbetween during haiz, both climax.
