When cleaning borosilicate glassware use a soft bristle brush with either a wooden or plastic handle to avoid scratching or unnecessary abrasions. Make sure you also reach into cracks, curves and groves to get rinsing done quickly and thoroughly. Avoid using hydrofluoric acid on your borosilicate glass as it is highly corrosive and can cause irreparable damage if exposed to the material for extended periods of time without protection and sanitization. Stronger alkali soaps and acids should also be avoided as they will wear away at your glass over time leaving it cloudy and dull in color.
