Had these stains on my steps last year as well - pretty mild, but, I want them gone
Have no recollection as to what product I used last year - totally escapes my mind
Got the Jack's as shown above and have no problem meeting all the recommended parameters - except - I just raised my TA - it was way low (which it likes to do!) and I raised it to about 110
So - and I know this is an ignorant question, b/c - I AM ignorant...
But - how important is having the TA less than 80?
If I just wait a few weeks it will likely have dropped back down, but, I'm being impatient
Thanks
