Abstract
The invention relates to neutral cleaning compositions comprising a surface modification polymer to beneficially aid in removing typical bathroom soils, such as hard water deposits, at a neutral pH. The neutral cleaning compositions effectively remove and/or otherwise assist in general cleaning of difficult bathroom soils without the harsh effects of a traditional acidic cleaning composition and without requiring PPE. Additionally, use of the cleaning composition beneficially aids in and/or improves subsequent cleanings.

A cleaning composition comprising:
- about 1 wt-% to about 80 wt-% of a buffer, an alkalinity source, and/or a chelant;
- up to about 30 wt-% of a surfactant;
- up to about 30 wt-% of an organic acid;
- from about 0.1 wt-% to about 40 wt-% of a cationic, hydrophilic surface modification polymer comprising a polyampholyte;
- up to about 75 wt-% additional functional ingredients;
- and
- about 20 wt-% to about 90 wt-% water,
