Richard 95005 White tampico fiber brush (4'').

unlike a paint brush, you want a wash brush heavily charged — dip deep and let the fiber take on solution; the capacity is the feature. Scrubbing: moderate pressure and a working, overlapping stroke that agitates the solution into the pores and joints; let the liquid and the chemistry do the work rather than trying to abrade with the soft fiber. Cleaner safety: acids and alkalis demand eye protection, gloves, and often pre-wetting the masonry so the cleaner doesn't burn in unevenly; always follow the cleaner maker's dwell time and rinse instructions. Rinsing the brush: flush tampico thoroughly with clean water after any cleaner — natural fiber lasts far longer when the chemistry isn't left to dry in it — then hang it to dry rather than standing it on the fiber, which takes a permanent set. Kept rinsed and dried, a tampico brush is a multi-season tool.
