A sanitizing applicator for applying a liquid sanitizer to a surface. The sanitizer may be a quaternary ammonium compound (QAC)-based or chlorine-based sanitizer containing positively charged ions at an effective concentration level for killing a predefined percentage of microbes present on the surface. The applicator includes a breakable internal reservoir for retaining a quantity of the sanitizer, and a positively charged nonwoven fabric covering the reservoir. The fabric is constructed using a positively charged binder to bind together the strands of the fabric, and is optionally treated with a positively or neutrally charged surfactant. The positive charge of the fabric prevents the fabric from neutralizing the positively charged ions in the sanitizer when the breakable internal reservoir is broken and the sanitizer is applied to the fabric.

What is claimed is: 1. A sanitizing applicator for applying a liquid sanitizer to a surface, said sanitizer comprising positively charged ions at an effective concentration level for killing a predefined percentage of microbes present on the surface, said applicator comprising: a breakable internal reservoir for retaining a quantity of the sanitizer; and a positively charged fabric covering the breakable internal reservoir, said positively charged fabric including an adhesive binder that binds together a multiplicity of strands to form the fabric, said binder including positively charged ions that provide the fabric with a predominantly positive charge; wherein the positive charge of the fabric prevents the fabric from neutralizing the positively charged ions in the sanitizer when the breakable internal reservoir is broken and the sanitizer is applied to the fabric. 2. The sanitizing applicator of claim 1, wherein the positively charged fabric is also treated during manufacturing with a positively charged surfactant that is embedded into the strands of the fabric. 3. The sanitizing applicator of claim 1, wherein the positively charged fabric is also treated during manufacturing with a neutrally charged surfactant that is embedded into the strands of the fabric. 4. The sanitizing applicator of claim 1, wherein the breakable internal reservoir includes at least one plastic bubble filled with the liquid sanitizer, said plastic bubble having a tensile strength such that the bubble will burst and release the sanitizer when a user squeezes the applicator with a predefined amount of force. 5. The sanitizing applicator of claim 1, wherein the breakable internal reservoir includes a plurality of adjoining plastic bubbles filled with liquid sanitizer, each of the plastic bubbles having a tensile strength such that the bubbles will burst and release the sanitizer when a user squeezes the applicator with a predefined amount of force. 6. The sanitizing applicator of claim 5, wherein the applicator is rectangular in shape, and the breakable internal reservoir includes a plurality of elongate reservoirs oriented so that the reservoirs are parallel to a longitudinal axis of the applicator. 7. The sanitizing applicator of claim 5, wherein the applicator is rectangular in shape, and the breakable internal reservoir includes a plurality of elongate reservoirs oriented so that the reservoirs are perpendicular to a longitudinal axis of the applicator. 8. The sanitizing applicator of claim 5, wherein the breakable internal reservoir also includes a stiff lattice-type framework in which the plurality of plastic bubbles are mounted. 9. A method of manufacturing a sanitizing applicator, said sanitizing applicator being utilized to apply a liquid sanitizer to a surface, said sanitizer comprising positively charged ions at an effective concentration level for killing a predefined percentage of microbes present on the surface, said method comprising: filling a breakable internal reservoir with a quantity of the sanitizer; constructing a positively charged nonwoven fabric, said constructing step including: selecting an adhesive binder comprising predominantly positively charged ions; and applying the binder to a plurality of loose strands of material to bind the strands together into a web-like structure forming the fabric; and covering the breakable internal reservoir with the positively charged nonwoven fabric. 10. The method of claim 9, further comprising the step of selecting a suitable liquid sanitizer comprising positively charged ions at or above the effective concentration level for killing the predefined percentage of microbes present on the surface. 11. The method of claim 9, further comprising the step of: constructing a plurality of adjoining plastic bubbles for retaining the liquid sanitizer, each of the plastic bubbles having a tensile strength such that the bubbles will burst and release the sanitizer when a user squeezes the applicator with a predefined amount of force. 12. The method of claim 11, wherein the step of constructing a plurality of adjoining plastic bubbles includes mounting the plurality of plastic bubbles in a stiff lattice-type framework. 13. A combination for sanitizing a surface, said combination comprising: a liquid sanitizer comprising positively charged ions at an effective concentration level for killing a predefined percentage of microbes present on the surface; and a sanitizing applicator comprising: a breakable internal reservoir for retaining a quantity of the sanitizer; and a positively charged fabric covering the breakable internal reservoir, wherein the positively charged fabric includes an adhesive binder that binds together a multiplicity of strands to form the fabric, said binder including compounds with positively charged ions that provide the fabric with a predominantly positive charge; wherein the positive charge of the fabric prevents the fabric from neutralizing the positively charged ions in the sanitizer when the breakable internal reservoir is broken and the sanitizer is applied to the fabric. 14. The combination of claim 13, wherein the positively charged fabric is also treated during manufacturing with a positively charged surfactant that is embedded into the strands of the fabric. 15. The combination of claim 13, wherein the positively charged fabric is also treated during manufacturing with a neutrally charged surfactant that is embedded into the strands of the fabric. 16. The combination of claim 13, wherein the breakable internal reservoir includes at least one plastic bubble filled with the liquid sanitizer, said plastic bubble having a tensile strength such that the bubble will burst and release the sanitizer when a user squeezes the applicator with a predefined amount of force. 17. The sanitizing applicator of claim 1, wherein the positive charge of the fabric substantially prevents the fabric from neutralizing the positively charged ions in the sanitizer when the breakable internal reservoir is broken and the sanitizer is applied to the fabric. 18. The sanitizing applicator of claim 1, wherein the positive charge of the fabric completely prevents the fabric from neutralizing the positively charged ions in the sanitizer when the breakable internal reservoir is broken and the sanitizer is applied to the fabric. 19. The sanitizing applicator of claim 1, wherein the positive charge of the fabric prevents the fabric from neutralizing most of the positively charged ions in the sanitizer when the breakable internal reservoir is broken and the sanitizer is applied to the fabric.
