CLEANING LIQUIDS
Phosphoric Acid Cleaner
This is a phosphoric based acid cleaner containing detergents
properties for the removal of excess grouting and cement smears,
usually used diluted with water in a ration of 1 part acid to
10 parts water for final clean up of excess grout from tiles.
NOTE: Acid cleaner must be handled with care and protective clothing
and goggles must be worn.
Read safety instructions before opening and applying.
Sodium Bicarbonate
A 5-10% solution may be used to neutralise the acids used in grout
removal. After reacting the materials should be washed off with
copious amount of water.
Cleaning Detergents
These vary dependant upon the application as follows:
Post phosphoric acid cleaner
To clean up after phosphoric acid, the most suitable is a neutral
to slightly alkaline cleanser – pH 7 to 9 – designed to neutralise
the phosphoric acid and maintain tiles in a clean condition.
For daily cleaning, a detergent with a pH in the range of 7-9
should be used.
For heavy cleaning, an organic acid cleaner with a pH of 2, but
no mineral acid content or an alkaline cleaner with a pH of up
to 11 may be used provided its sodium or potassium hydroxide content
is no more than 0.01% in the liquid used.
For infrequent heavy duty scrubbing of small areas higher alkaline
cleaners up to pH 13.5 may be used provided the sodium or potassium
hydroxide content is less than 2%, but they should be removed
from the surface with copious quantities of water.
Before using these cleaners (1., 2. & 3.) get written advice
from the chemical manufacturer as to its suitability, application
and frequency of use for fully vitrified porcelain tiles.
Water
Clean water is the big secret in cleaning, it should be used to
flush all detergents and acids used in cleaning.
