Can anyone buy High Strength Brick Acid?
No, it is a professional-trade product. Therefore, it is not for sale to the general public unless they hold an EPP licence.
When should I choose this over the standard Brick & Patio Cleaner?
Choose it when mortar haze or efflorescence will not lift at 4:1 with the standard cleaner. Also, choose it when you need fewer drums on site for a big job. For light domestic clean-down, the standard cleaner is usually enough.
Will it attack stainless steel?
Yes, HCl and its fumes attack stainless steel and aluminium. So, mask and protect metalwork thoroughly before you start.
How do I dispose of rinsings?
Rinse with plenty of fresh water to dilute as you go. However, do not dispose of concentrated rinsings in a drain that leads to a watercourse, and never tip onto plants or grass. Finally, always follow local disposal regulations.
