We just went through renovating a cigarette smoker cat spray house (an inherited tenant) and after 3 full scrubbings with TSP, soaking slab and subfloors in vinegar several times over several weeks, then painting subfloors with Kilz, duct cleaning, etc., it finally seems to be resolved.  

So, to then soak a landlord again for the right to end the contract, is unreasonable - to put it nicely.Now, if there was no upfront fee to find a tenant, etc., and the PM was relying on the next 12 months percentage of the rent to make their time worthwhile to find the tenant - then a termination fee would be fair.But, in my opinion, a termination fee is double-dipping.  

I will use an iron and brown bags to melt and soak it it up  (fingers crossed).  

Use Odoban and soak the floor then let it dry.

Basically, as I understand it, all the new development has eaten up former prairie areas that used to soak up the water.

Does this new tenant take longer, hotter, soaking showers or baths?

I think you can get one that resists soak-thru of fluids.

Seems like it soaks in..

Trouble is, many PMs out there don't know the difference and the owner gets soaked. 

Make them think you're giving them a huge favor, in exchange for a spotless unit, and you'll have far less to do after they move out.No need to soak them.
