[Histonet] LTP fluid with Phenol

Here is the approximate chemical make-up of LTP with Phenol.  (LTP stands for Long Term Preservation)
Ethanol  48.%
Formaldehyde 20.%
Ethylene Glycol 4.%
Phenol 11.%
Glutaraldehyde 4.%

Due to the presence of Ethylene Glycol, I would let the tissue set in a separate container of 10% Neutral Buffered Formalin for 24 hours before processing as usual.
I hope this helps. Terri

I got some cadaver tissue floating in "LTP embalming fluid w/ phenol".
Can I put those straight into the processor? Or has to be rinsed/soaked before? If so what should I use?
My Internet searches did not bring up anything useful.
Thank you!
