Problem with exterior wood stain being used inside

[Peter Castrianni]

If anyone has a good knowledge on wood stain and can provide your input that would help.  I am building a home that has toungue and groove interior walls and ceilings.  The house will be used as a short term rental.   I just had the house stained by my general contractors sub and I just found out that he used exterior wood stain throughout the interior of the home.  The stain he used was Flood semi transparent.  Everything I read online says DO NOT use exterior stain on the interior due to the fact it gives off harmful chemicals.  I reached out the the stain company and they told me it it not suppose to be used inside and to either let it cure with a lot of ventilation or strip it.  They also said that there is a chance the stain can let off harmful chemicals in the future with a change in temperature.  I am really not sure what to do at this point.  So my question is if i let the home air out well is it safe?  Am I worrying to much?  Should I just leave it?  Am I being irrational to have him strip sand and retain?  To strip and sand the whole house would be tedious and expensive.  Should I expect the painter to cover the cost or is that something I should cover?  Any input is helpful

Thank you
