Microbe-Lift Soy-Based Birdbath & Statuary Cleaner – 32 Oz – Safe for Birds – Cleans Garden Statues, Stone, Brick & Sculptures – Natural, Non-Toxic Formula

Worked great at cleaning the large terracotta bird bath. Got rid of 2 yr old grim! Cleaned it twice. Will clean it again in the summer and fall.We also bought 2 new bird bath brushes to use. NOTE: if your brush has plastic bristles do leave it in the sun. We did and the bristles disintegrated!lol

Works well and doesn't harm the birds

It did a very good job in cleaning the birdbath. Wish it could’ve help slow down the growth of the black algae or whatever it is that grows inside the birdbath. But the cleaning does last 2-3 weeks, so can’t complain. I would recommend this product.

Works great for cleaning birdbaths

The bottle, it was easy to use, but the product did not clean the bird bath at all. Probably not worth the price, but it is environmentally friendly and also pet and bird friendly.

When I had my pond, I always had lots of algae. Micro lift never let me down when it came to getting rid of the algae and having my water crystal clear. Now that I only have a small fountain I am using this item and finding it lives up to its big brother that I used for my pond. It is so nice not to have algae in my fountain, and the birds are loving it.

We tried different cleaners to get the birdbath clean with products we knew would not harm the wildlife, but nothing removed stains as well as this product. Though vigorous scrubbing still was necessary, at least it removed a lot of stain. We will buy again when it's gone.

I've used it 3 times so far and it's slowly working. To be fair, the bird bath hasn't been properly cleaned with any product other than water and a scrub brush for a very long time. You can see in the pic where the build up is starting to come off. The most current use today shows the the groove in the leaves are starting to come clean a little bit. I spray it, let it be for around 5 minutes or so, and come back and scrub it with a wet scrub brush. Then I rinse and fill the bird bath again. It's not a miracle worker but it's working.
