Important instructions for cleaning TECU surfaces used for ex-and interior claddings
Warranty claims will lapse if application and processing instructions are disregarded
TECU Products with natural surfaces are developed and manufactured for facade and roof cladding-
but can be used for interior applications as well.
As used for exterior applications TECU products are generally maintenance-free;rainfall suffices to
clean the surface in most situations.For interior applications,or accessible facade areas,some points
should be considered.Especially for interior applications a protective conservation of the surface should
be considered,because an all-over natural weathering of the complete surface is not given.
For cleaning window glazing and cills/surrounds within a TECU products cladded application,neutral
soap should be used with plenty of clean fresh water without exception.During cleaning,attention must
be paid to clean off any dirty water,because otherwise dirt particles-especially when TECU Patina
have been used-will adhere to the patina pores and may cause a long-lasting pollution of the patina.
Cleaning products with acidic/alkaline content,in particular ammonia should never be used,because
these might create irreversible stains on the surface.As well cleaning products with strong chemical
reagents should not be used,because these might create irreversible stains on the surface also.
The same applies to areas of claddings with TECU Products which have been soiled;these should be
cleaned with water and neutral soaps and a soft brush.If an abrasive cleaning method,using a plastic
fleece or hard sponge,is necessary to clean strong soiled areas or patinated surfaces,please consider
during the cleaning process the rolling direction of the surface.Any circular movements should be
avoided.Due to the further weathering within the cleaned areas,they will mostly blend together with the
non cleaned rest of the surface.For interior applications this does not apply,due to the lack of the all-
over natural weathering process of the surface.
Oil contamination can removed by using solvent(MRR-Zwischenreiniger-Solvent Remover,
produced by MR Chemie,Unna,Germany).Adhesive residues can be removed using acetone or citrus
based cleaning agents.
Fresh Finger-markings on bright surfaces on TECU products,e.g.in areas exposed to significant
perspiration from hands,where accelerated oxidation has caused spotting,can be removed by using a
special stainless-steel cleaning agent(saBesto-Stainless Steel Care Spray-article number:0893
121,by WURTH).Carry out the cleaning process in rolling direction of the surface.Any circular
movements should be avoided.For the final cleaning process a suitable polishing cloth must be used.
Please pay attention to the producer's instructions.
