What's the best way to remove grout of newly laid floor tile

Roach wrote:Hi do you know how much your supposed to dilute this agua fuerte by? Like 50% fuerte and 50% water etc?

I've generally used it full strength, but be careful with it. It won't hurt glazed tiles but it could dissolve the grout joints if it entered them. It also eats skin, so best to wear rubber gloves.

Thanks everybody for your suggestions.

I can confirm that following the directions off the bottle (10 parts water for one part fuerte) for agua fuerte yielded no results, but after using it full strength, it worked!

I used a kitchen foam brillo pad thingy and the fuerte along with a lovely pair of pink marigolds lol. Job done.

If anyone else needs to give this a go, test it on a spare tile first and wear safety gear. As others have mentioned don't breathe the fumes either. Oh and don't get it near any metal surfaces as this will start to dissolve it. Even the knife used to cut the top off has been stained with even a tiny amount. Be careful. Good stuff but dodgy.

Hi as roach says be very careful you can not buy this in the UK for good reason! It can be very dangerous unless you know what you are doing.

Remove contaminated clothing and shoes, rinse the skin or shower the affected person if appropriate with plenty of cold water and soap
neutral. In case of an important condition, see a doctor. If the product causes burns or frostbite, do not remove the
clothing because it could worsen the injury produced if it is attached to the skin. In the case of blisters
the skin, these should never burst as it would increase the risk of infection.
By contact with the skin:
Remove the affected person from the place of exposure, supply him with clean air and keep him at rest. In serious cases like stop

oxygen, etc.) requiring immediate medical assistance.
