Hey guys i just have a couple of questions

i just bought a new baby redtail boa about a week or a little more ago and i put her in roxy's old cage which is a 30 gallon tall,since i hear that boas like to climb i thought it would be a good idea to get some wood and put it in her enclousure with her since its nice and tall. So i got some nice pieces of wood when we went hiking this weekend and i put them in a 10% bleach solotion but to me it just doesnt seem like they are clean one piece is kinda chipping and i dont know if it has termite damage or was rotting, what should i do ?

Also, i have a 30gal repti carpet that roxy was using before i moved her to a bigger tank and the boa is on newspaper, would it be alright to just wash Roxy's carpet and put it in with the new snake ??
