Impurities

Q: I recently purchased a room carpet from a non-Muslim which I intend using as a carpet to perform Salaah on. 

There are no apparent traces of najaasat on the carpet but there are a few stains which look like they may be from food or drink. 

The carpet is too thick and big to be soaked and squeezed. In order to ensure the carpet is paak, must it be washed once, then left to dry; then washed again and left to dry, and washed a third time and left to dry; in order for it to be paak? Or will one wash and soak be sufficient?

Q: If someone touches blood from a wound which is not flowing, but a few seconds after touching it the blood starts flowing. Is that blood that he touched paak or napaak?

Q: Is the outer of a babies nappy napaak?

Q: I had a dirty wet wipe on the floor. As I picked it up, it touched my duvet. Would I need to wash my duvet?

Q: Is it permissible to massage the body with cannabis oil due to pain? 

Also is it paak?

Q: Are these halaal? 

Mineral oil, Paraffin, microcrystalline wax, tocopheryl acetate, fragrance. 

They are the ingredients of vaseline petroleum jelly skin protection. I searched them and mustakshif app said its haraam. I have a little amount of this on my shirt and phone because it was on my hands. 

Q: My 3 month old son had a portion of his clothes wet with urine. I removed the onesie and placed it carefully on the bed with the urine part facing upwards so I could wash it. 

I fed my son and when I was done I picked up the onesie and went to wash it. Then I saw the onesie was completely dry all over and I couldn't find the spot where it was wet previously. 

Can I use this onesie now or must I wash the whole thing?

Q: As we all know that almost all houses have lizards. My question is: 

1. Lizard's dropping is found on the wall and it has dried. If we paint the wall and the brush touches the impurity, does it make all the wall with new paint impure? 

2. If this wall with new paint dries and someone with wet hand touches it, but the traces of color is not visible, will his hand be pure?

Q: What should we use in place of cream, bath soap, shampoo and deodorant?

Q: If you pour water (flowing water) over a wound that is still bleeding a little when checked with tissue but the water falling off is clear (no detectable traces of blood) even though logically there would technically be blood in it, is that water and its splashes impure? Are the areas on your hand that are now wet around the wound considered impure?
