I used the kinesiotape but before doing the ghusul, I removed it, but after an hour I noticed that there was still a bit of glue from the tape, a small line on my arm, is the ghusul not valid? And do I have to repeat the whole thing? Thanks?
You must be sure that every glue or any other material is completely removed away from your body before performing Ghusl. If you see a bit of glue on any part of your bod after Ghusl, the Ghusl is invalid and you need to re do the Ghusl after removing it.
Wassalam.
