hi, i bought some fairly expensive product for treating basement timbers infested by borers, and i may have let it get too cold/freeze in the bottle such that the borate (disodium octaborate tetrahydrate) crystals are coming out of solution. do you think it is possible to just reheat it to redisolve them? i bought the product but it is something that people make at home ith borax, boric acid, and some form of glycol. any advice much appreciated. here is a recipe for diythat should give some idea of the chemistry involved http://alsnetbiz.com/homeimprovement/homemade.html

Will freezing make Boracare ineffective?
Answer:
Yes, allowing Boracare to freeze can make it ineffective. It should be stored in a controlled temperature area out of direct sunlight and extreme temperatures.
