Basic cleaning in sanitary areas
This is the process
Sanitary floor tiles: pre-soak tile areas with seams; apply
solution. Can be done with foam gun. Floor tiles are
one-disc rotary machine and brush. When manually
cleaning, use of micro-bristle mop. Use roller brush machine for
to reach seams. After cleaning, thoroughly
with clear, cold water. Alternatively, remove
dissolved dirt with high-pressure cleaner. Clean stoneware or
safety tiles with
micro-porous surfaces, microfiber mop covers
with roller brushes that have microfiber or
melamine cleaning pads.
Sinks and fittings: apply cleaning agent and wipe with nonscratch
cloths. Wet acid-resistant fittings with cold clear water
and then treat with basic cleaner. Mechanically re-treat lime
and other deposits around fittings with non-scratch cloths and
milk if needed. Rinse detergent residues thoroughly with
Walls: larger surfaces (walls, doors, partitions) are usually cleaned
with squeegees and window/
tile mops. Alternatively, apply
solution with foam gun. Manually clean small surfaces
with cleaning cloths. Thoroughly pre-wet cement-bound seams
of wall tiles when using acidic cleaners; subsequently, thoroughly
rinse off cleaning
residue with clear water. Mechanically
seams with seam brushes if necessary. Afterwards, rinse with
clear, cold water.
Toilets/urinals: flush, raise toilet seat and lid, squirt concentrated
cleaning agent into toilets and urinals, including rims. (Do not
use conventional/surfactant-based cleaning agents for waterfree
that trap odors with oil-based barrier liquids. By
the barrier liquids, the cleaning agents could affect/
eliminate their function. Use conventional sanitary cleaners on
water-free urinals with odor-trapping rubber membranes.) Clean
toilets and urinals on the inside with toilet brushes. This cleans all
visible siphons. Thoroughly wipe and dry toilet covers and seats
with all-purpose cleaner because sanitary basic
cleaners can alter
the colors of plastic surfaces.

reacts very sensibly to mechanical treatment as well
as to highly alkaline or highly acidic cleaning solutions. It should
therefore be cleaned only with a suitable, diluted acidic cleaner.
Here, too, the part should be thoroughly rinsed with clear water
Alternatively, non-abrasive cleaning milks in
with non-abrasive sponges/pads can be used to clean
lime and dirt from aluminum surfaces.
Plastics often have low acid-resistance
The quality of plastics – e.g. toilet seats – varies. It can never
be assumed that the material is acid-resistant. Toilet-seat
often have limited acid-resistance because the plastic
contains lime aggregates. The constant use of any acidic
agent containing urine or uric acid should be avoided. In daily
maintenance cleaning, toilet seats should be wiped with clear
water after cleaning.
During basic cleaning, only all-purpose or neutral cleaners
be used. Plastic surfaces should be wet-cleaned with the product
solution. Manufacturers recommend that after cleaning, hinges
be dried with a soft cloth so that no moisture remains. One thing
applies for all basic sanitary cleaning: the cleaning interval and
the system used must be coordinated.
Problem: mold or mold stains in seams
Mold stains are blackish-brown discoloration on cement and
joints. These are the excesses of mold. Mold infestation
is always the result of high humidity connected with inadequate
air circulation and ventilation. It is definitely not the result of
inadequate cleaning. Mold can only be removed from seams by
exchanging the seam material. Removal of the damaged material
and its replacement by specialists with special fungicidal seam
material is recommended. In addition, the ventilation should be
adapted to ensure better air circulation. Alternatively, the seams
can be treated with chlorinated
products. This is only a short-term
remedy, however, because it only bleaches the seam surface.
mold can quickly grow again from the seam material to the surface.
Thus, mold cannot be removed with and killed by chlorinated
products in the long term.
Red deposits on seams are so-called red algae, which results from
high humidity plus dirt deposits on tiles, seams and even the seals
of shower partitions. This can be prevented by basic and regular
cleaning of the seals with a seal brush, which hinders dirt and
algae from collecting in the porous material.
The main requirement for this is strong basic sanitary cleaners
with the right acidity levels. They must also be gentle for humans,
materials and the environment, and may not contain any volatile
acids such as the particularly aggressive hydrofluoric, acetic or
hydrochloric acids. Additional requirements include that basic
sanitary cleaners be viscous enough to adhere to vertical surfaces,
which makes them compatible with surface disinfectants and puts
them on RK lists. Corrosion inhibitors that prevent rust are also
helpful components of basic sanitary cleaners.
The interval is important
Maintenance and basic sanitary cleaning should be completed at
suitable intervals. The greater the intervals between maintenance
cleaning procedures are, the more frequently basic cleaning must
be carried out.
In contrast, the more regularly and specifically maintenance
is done, the more seldom basic cleaning is needed. The
