Keeping surfaces cleaner
Dirt is attracted to surfaces that are hydrophobic, in other words, afraid of water. When surfaces are more hydrophilic, or water loving, dirt is repelled. This is called anti-soiling.
Silica particles in colloidal silica dispersions have many surface hydroxyl-silanol groups, which are very hydrophilic. As a result, when formulations are produced with colloidal silica, treated surfaces become more hydrophilic and attract less dirt.
Anti-soiling is a very important ability for exterior coatings; the better these coatings resist soiling, the fresher and cleaner they look. And when cleaning is required, dirt is easily removed by rinsing.
Additionally, when colloidal silica is used in glass cleaning products, water is less likely to form droplets or fog on the surface, so called anti-fogging.
