Hi,
I have some minor brickwork efflorescence on some garden beds around the house. The garden beds have been internally coated with 2-3 coats of Ormonoid Bitkote No.3.
What is the best product to use for cleaning the efflorescence off the brickwork to ensure it won't come back again?
I've seen some videos on using an acid cleaner and then a Ph balancing formulation to neutralise the bricks to avoid it coming back again. However I'm not sure on the best products or the best process.
Cheers
