That's cleaning up great, but I still think I'd want to try and hit it with an acid and oxy. But as long as the customer is happy and you don't get a call back that's all that matters. Fajitas are delicious also.
Keep in mind, you never know what the customer "attempts" to do on that spot before you arrive. It could be some google concoction that the "lab scientist" has put together from her selection of chemicals under the sink or some bissell chemical as well.
So now we have a problem of dried chemicals sitting on top of urine and now our teachers tell us to dump boiling water with sodium percarbonate foaming and fizzing on top of it, only to reactivate the dried chemical that's been sitting and rising in ph to discover that you have a high risk of color loss
Or on using an enzyme on that spot. Enzymes and acid take time when there's another dried chemical on that spot. So you do what the "teacher" tells you again and spray the enzyme on that spot, now you're giving it time to gradually make it's way under the carpet to allow for a follow up call of wicking
So, instead of risking color loss or wicking, try this. It can't hurt.
1. Do as pictured: Just do a couple wand passes over the spots and dry pass as normal over the dry spots
2. Treat the whole room with your normal juice (preferably 8.5-10ph) in your HF and HWE as normal
3. Collect check and expect a compliment from your customer
And don't forget that dried urine is just yellow salt with some bacteria. And what happens with you put salt in hot water? It dissolves. So the goal is to liquify the dried urine so it can be rinsed out
Now if it's huge areas where a male/great dane pissed on several times, the 5 gallon bucket dump is the best method. But on 9 out of 10 jobs where these people love ankle biter shitzus, this method works
