How Does It Work If It Has No Biocide?

This eco masonry cleaner works by using nano-size energy packages that penetrate and get underneath the dirt or algae (many a ‘dirty’ patio or war memorial or masonry like sandstone are in fact living microorganisms called algae that thrive in our damp climate). They do this by breaking the surface tension that holds dirt and algae embedded on a substrate ready for easy removal.

The cleaning action of BuildKleen masonry cleaner is powerful and effective and yet non-corrosive, non-acidic, non-toxic, and non-hazardous and the product is even certified as food safe; it does not kill the green growth as with biocides used in most cleaners and is safe to use near a water course.

How To Apply It:

Use of a pressure washer on low pressure setting in conjunction with the use of BuildKleen masonry cleaner can be helpful to send the loosened dirt on its way after treatment. If you are washing a patio that is monoblocks please use a hood washer to save blasting out kiln-dried sand between the blocks. Brush off leaves, cobwebs and debris before you begin and apply generously with several coats it you are spraying the product.

Apply our eco-friendly masonry cleaner with brush or sprayer, saturate the surface well and then agitate with a brush – ideally wait about 15 minutes before rinsing off the dirt.
