Just wondering if I could get some advice on cleaning cement/mortar from my slabs. In some areas its just stains and in others, its quite heavy (lumps, smears, etc).
What would be the best way of cleaning? Would a hydrochloric acid cleaner help? If so, what is the best method for using such a cleaner?
If it helps, the type of slabs I have are in the following link:
There is some good stuff on the market I used some stuff called cement away it's quite good but make sure it's ok for your slabs first, also if you have lumps try gettting the worse off first with a scraper or a wire brush again avoid damaging the slabs
Lithofin builders clean is also worth a squirt as well. Follow the instructions to the letter and obviously test on a small patch first. Soak the area first as well to reduce the impact of the acid and also over dilute it and reduce incrementally as required
Thanks very much. Really appreciate it. Just rang and they advised they do two products which can help, Cement-Away or MN Builders Cleaner. Which one to go for now? lol
