Efflo-Go! Pro Grade Efflorescence and Calcium Deposit Remover for Masonry Concrete Brick & Tile (4)

With two go-a-rounds, this took off about a 1/2 inch of calcium build up on our bluestone. Let it sit for about 2 min then it came off in chunks with a power washer

i used the product for what it was intended for on bricks. it removed nothing, i even scrubbed just like it stated. Its useless. It says parts of 4/1 no good, then i did 2/1 and still no good. Very disappointed.

This actually works help me get rid of white stuff on my brick

Removing lime off of Brick walls. Did not do the job.

Wiped away efflo on brick I cleaned. Great product!
