How to clean mortar stains off your paving slabs?
The best practice that you may or the contractor should have done earlier was to use a sponge and water to clean as you go on laying these slabs and haven’t got them there in the first place.
Because once dried, mortar/cement stains can be a headache to get rid off of the paving slabs and you can have a hard time individually scraping off each mark.
And what type of slab you have determine how easy or difficult would it be to get the cement or mortar. Of course, porcelain will require less effort (however, may need a good product to get the stains out) due to it being nearly non-porous than natural stones like sandstone which is a very popular paving option.
Things get more complicated if it’s sawn and honed sandstone and the same is the case with limestone slabs. Because with natural stones, you’re restricted with what you could use for cleaning.
Yes, for this reason there exist cleaners to make your job easier but not all the cleaners might work the same and there are certain things that you need to keep in mind because these cleaners are also enough to damage the slabs making the condition 10x worse than what it was with the stains alone.
Brick acid is definitely an aggressive way to get the cement off of your slabs, especially for the natural stones even though people have suggested using it in a certain way but it should be the last option.
