Precautions for cleaning① Removing adhesive remaining on the protective ﬁlm
Wipe oﬀ adhesive using a sponge or cloth moistened withalcohol, benzene, or thinners, or a mixed solution consisting of
alcohol and toluene or benzene (in sequence from the weakest
acting liquid). It is important to wipe the surface of the titanium
with an unused, clean cloth before these solvents have dried.

① There are various causes of contamination and discoloration oftitanium building material, so it is necessary to use a cleaning
method that matches the particular circumstances. Do not
abruptly start cleaning the entire surface. First carry out test
cleaning on a small area, and check the removal of thecontamination or discoloration. If the result of the test issatisfactory, use that method to clean the entire surface.

② Removing contamination due to ﬁnger marks or dirt fromthe hands
In almost all cases, you can remove contamination using aneutral detergent or soapy water. If you are unable to do so, usean organic solvent (alcohol, benzene, etc.).
In this case, you must observe the abovementioned precautions.
③ Removing contamination due to rooﬁng material andconcrete
Wipe away contamination using a sponge or cloth moistenedwith a 5% solution of hydrochloric acid in water.
④ Removing contamination due to zinc from scaﬀolding
material
Wipe away contamination using a sponge or cloth moistenedwith a 15% solution of nitric acid in water.
⑤ Removing contamination due to rainwater or dust
In almost all cases, you can wipe away contamination using asponge or cloth moistened with a neutral detergent or an alkaline
detergent. If you are unable to do so, you may be able to remove
the contamination by applying a cleaner containing an abrasive
to soft cloth, and then rubbing gently and uniformly.
The above is a description of the various cleaning methods.
In all cases, thoroughly wash the surface with water after
cleaning, and ensure that no traces of cleaning agent remain.
⑥ Removing contamination from colored titanium
Of the abovementioned cleaning methods, do not remove
contamination using hydrochloric acid, nitric acid, or a cleanser,
because the ﬁlm that produces the color will be aﬀected,
preventing the surface from being restored to its originalcondition.

② When using a cleaning implement such as a cloth, sponge,
loofah, scrubbing brush, cleaning brush, ﬁre nylon pad, and soon, be sure to move it in the direction parallel to the polishingmarks on the titanium. Also, move your hand in such a way as toapply a uniform force as far as possible. If you move thecleaning implement in circles, the contamination will be diﬃcult
to remove, and also the luster lines will be erased and color
irregularity will occur, marring the appearance of the titanium
surface.
③ Even in the case of fairy stubborn contamination, avoid using acoarse polishing agent, sandpaper, steel wool, or the like. Not
only will this erase the luster lines on the titanium, but also thesurface will become scratched, which may cause it to becomecontaminated.
④ When using a commercially available cleaning reagent to remove
contamination from the surface of titanium, clean not only thecontaminated part but also the vicinity as well. If you clean thetitanium surface only partially, irregular color will occur, marringthe appearance of the titanium.
⑤ When cleaning building tiles, marble, aluminum, and so on, if thecleaning reagent that you used splashes on the surface of thetitanium, be sure to wipe away the reagent with a damp cloth. If
you leave the reagent on the titanium, discoloration may occur.
⑥ In the case of colored titanium, consult with the manufacturer
prior to use.
