Impurities

Using vaseline petroleum jelly

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. 

Washing clothing that was soiled with urine

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?

Lizard droppings on a wall

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?

Are the splashes of water over non-flowing blood impure?

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?
