Stain­less steel care

PRAC­TIC­AL TIPS FOR STAIN­LESS STEEL CARE

Lad­ders, stairs, rail­ings, handles, over­flow gut­ter grilles, showers and many oth­er com­pon­ents in or around the pool are made of stain­less steel. And for good reas­on: Vari­ous kinds of steel, which are com­monly referred to as “stain­less steel“, are par­tic­u­larly suit­able for use in this area due to their cor­ro­sion res­ist­ance. How­ever, stain­less steel also requires pro­fes­sion­al care to ensure last­ing res­ist­ance.

Stain­less steels are far more cor­ro­sion res­ist­ant than many oth­er metals. Through oxid­a­tion, the chro­mi­um com­pon­ent forms a pro­tect­ive film on its sur­face - the pass­ive lay­er. It devel­ops again and again through the effects of oxy­gen, even after dam­age, and pro­tects the com­pon­ent from neg­at­ive influ­ences. If this pro­tect­ive film can no longer form again, stain­less steel loses its rust res­ist­ance.

Dirt is depos­ited on stain­less steel in the swim­ming pool area and chlor­ides are accu­mu­lated, pre­vent­ing the form­a­tion of a new pass­ive lay­er. In the long run this leads to pit­ting or rust­ing. The com­pon­ents should there­fore be reg­u­larly cleaned of residues. On stain­less steel parts that are not con­stantly in con­tact with swim­ming pool water, you can remove depos­its with com­mer­cially avail­able stain­less steel clean­er and a cloth/sponge or rinse off with tap water. Do not use clean­ing agents con­tain­ing hydro­chlor­ic acid or chlor­ide and do not use metal­lic objects such as clean­ing pads or steel wool! The sur­faces of stain­less steel parts that lie under water can be cleaned by simply rub­bing them with no addit­ives.

In prin­ciple, all stain­less steel parts should be main­tained at reg­u­lar inter­vals. If the water qual­ity is unprob­lem­at­ic, it is suf­fi­cient to clean it twice a year. If your swim­ming pool is oper­ated at high tem­per­at­ures, the pH value of the water is very low or the swim­ming pool water con­tains salt, the installed stain­less steel parts should be cleaned at least once a month. For the first harm­less spots of cor­ro­sion, a slightly acid­ic spe­cial stain­less steel clean­er, avail­able from spe­cial­ist swim­ming pool deal­ers, can be used. Read the instruc­tions for use care­fully and rinse the stain­less steel parts with fresh water.

The prop­er remov­al of depos­its pre­vents rust form­a­tion on stain­less steel. The qual­ity of the sur­face plays an import­ant role: the smooth­er the stain­less steel, the easi­er it is to clean. We recom­mend elec­tro­pol­ished sur­faces for highly stressed com­pon­ents in swim­ming pools!
