You can use vinegar to clean CR tiles

JUST SCARED.

After a woman said she wanted to clean her bathroom but didn't have hydrochloric (muriatic) acid on hand, a friend suggested she do the same with vinegar, saying it will be cheaper, less dangerous, and less smelly.

“Pwede ‘nang pinakurat nga suka?” she asked

“Di mamatay ang kagaw ana, makurat lang,” her friend replied.
