The basic cleaner is used for cleaning when the pool is drained. Removes
limescale deposits, algae residue and other contaminants. Acidic preparation
based on phosphoric acid. After draining the pool, we very often find that its
surface is clogged with limescale and its surface is rough. Very often, algae
are overgrown in a thin crust of limescale, which should be able to reproduce
again after filling the pool. Therefore, it is necessary to thoroughly clean all
this deposit before filling the pool. Inorganic pollution is removed by acidic
products, optimally pool edge cleaner. Cleaning is a chemical reaction where the
cleaning agent disrupts the structure of the dirt. Therefore, the instructions
must always be followed - that is, apply the product, let it act briefly so that
the product has enough time to react with the impurities and start cleaning
after a while. This saves a lot of work - in fact, all you have to do is wipe
the dissolved line with a sponge.
