Blew my expectations out of the water! I took a try and used this product outside of what it says it can do, and the results were awesome! My issue - I have a northern facing house, I had shingles put on my roof a good 8+ years ago and due to the lighting and shade around my house the roof stated to grow algae and moss. I sprayed this stuff on my roof with a cheap hand pump spray I picked up from Tractor supply. Within weeks and without even power washing or touching the roof, My roof looked brand new. The moss wilted, turned brown, and then into dust. Any signs of green algae was completely gone. Its been 9 months since I sprayed my roof with this and I still don't have any signs of algae or moss growth. It went through a snowy winter, rainy summer and a hot an humid summer and is holding up beyond my expectations. I plan on spraying other areas of my house with this stuff. The only reason for not giving it a 5th star is that its expensive. $32 for a gallon is a bit much don't you think?

Used citra Sheild on my porch posts over 2 yrs ago. Worked great !! Just sprayed again was seeing signs of mildew again. I am very satisfied with the results the 1st time ..Great product, just put in sprayer, wet & forget.. will be ordering another.

Easy to use, odor is somewhat present, didn’t bother our grass (although I did pre rinse the grass and again afterward). I only have 4 stars because we just used it today and I haven’t had time to witness it continuing to work. A+

This is a refill, I ran out of this and I use it on my deck, roof of my sheds, anyplace where I get that green growth. Spray it on and leave it, it takes awhile but it really does work.

The directions were clear. It was easy to use with the pump I bought with it. Best of all it worked. I used it on my deck, sidewalk, and hard plastic storage box. I just ordered another one to do some spots I missed.
