Brick, patio and mortar cleaners: safety data sheets
5 data sheets from the makers, one for each product, with what the hazard codes mean.
Brick acids, mortar stain removers and patio cleaners are often corrosive. Never mix them with other products, and wear chemical-resistant gloves and eye protection.
Use the data sheet for the exact product you buy. A data sheet covers one maker's product, and two products that look the same can be classed differently. Makers update their sheets, so check the revision. Your supplier must give you the safety data sheet for a hazardous product: ask for it if it didn't come with the delivery. We link to the makers' own sheets; we don't copy or change them.
