Blood and protien remover

I just wanted to let you know to try the bllod remover on those stains that wont budge. One of the jobs I did yesterday had this stain in the bedroom they had been looking at for five years after trying the pro spot, dry solvent (to no avail) I thought I’d try the blood remover it came up took a few times to get it all but I was very impressed makes me wonder how many spots I have gave up on that would have come out 😳 any way ya all have a great day!
