Doubts about the purity of the glue used on wooden flooring

Q: I have a wooden flooring and I found out after it has been placed that those who placed it used a wood glue which could contain najais substances. Actually, I read the notice on the box but not the full list of components was given, instead it wrote '...and other selected chemicals.' I am not sure if it contains alcohol or something. Can I pray Salah on it?

Watching Television

Q: While watching romantic scenes of movies some fluids comes out from my private part and I think it gets transferred to my clothes and bed sheets also. How should I wash these clothes to make it paak? If I cannot trace where in the bedsheet the fluid got transferred then what should I do? Do I have to wash the whole bed sheet or should I leave it? If the fluid gets dried and after sometime I sit on the bed sheet with my wet clothes, will my clothes get napaak?

Removing najaasat

Q: 

  1. My question is that after intercourse I wipe myself. If some sperm gets on my hand I wipe it with a tissue then put my qamees on. Is my qamees paak or do I have to wash my hands before touching anything.
  2. If something is najis. Do you have to wash it 3 times and squeeze each time or until there is no sign of najasaat?
