What is the difference between this product and No.12?
Hi,
Thank you for your question.
HG no.12 is a stronger cleaning product.
Both HG no.11 and no.12 are for cleaning cement residue from tiles, however no.12 is a highly concentrated, professional acid cleaner for the removal of cement, grout film, lime deposits and stubborn dirt, as well as efflorescence, saltpeter, rust.
