Acid washing is an effective technique for removing stains and calcium deposits that accumulate inside swimming pools. These stains and deposits can appear due to several factors, such as hard water, lack of regular maintenance or the use of inadequate chemicals. If not properly removed, these stains can become an aesthetic problem and can make pool cleaning difficult. Acid washing is an effective solution to maintain the appearance and functionality of your pool, and at American Crystal Pool we are ready to help you with this process.
