Surgical scrubs are disposable. Patient gowns are usually made of tough materials like cotton and polyester that can tolerate a fair amount of heat. If bleach in lukewarm water doesn't work, how about a boil wash? Boil washing is usually done at 90-95C, but I suppose you could achieve higher temperatures with a bit of extra pressure in a purpose-built machine. No living pathogen is known to survive an autoclave at 120C. Steam might be similarly effective on fixed hard surfaces like stainless steel and linoleum. Any non-disposable material that cannot withstand bleach, alcohol, or 120C for a few seconds a day probably doesn't belong in a hospital anyway.
