Claim 10

Dependent Claim 29 words

A cleaning and conditioning composition as recited in claim 1 in which the powder mixture includes a chelating agent for metals to remove metal marks and hard water deposits.

Claim 11

Dependent Claim 20 words

A cleaning and conditioning composition as recited in claim 9 in which the chelating agent is a polycarboxylic acid salt.

Claim 12

Dependent Claim 24 words

Claim 13

Dependent Claim 26 words

A cleaning and conditioning composition as recited in claim 11 including a water soluble film former to reduce the tendency of the abrasive powder to scratch.

Claim 14

Dependent Claim 19 words

A cleaning and conditioning composition as recited in claim 12 in which the water soluble film former is cellulosic.

Claim 15

Dependent Claim 21 words

A cleaning and conditioning composition as recited in claim 12 in which the water soluble film former is carboxy methyl cellulose.

Claim 16

Dependent Claim 33 words

A cleaning and conditioning composition as recited in claim 12 in which the powder abrasive has an average particle diameter in the range of 140 to 180 mesh measured on standard Taylor screens.

Claim 17

Dependent Claim 86 words

An alkaline cleaning and conditioning composition for ceramic surfaces comprising an abrasive powder mixture including from 70-90% of abrasive particles, from 0.1-1.0% of a nonionic surfactant, from 1-5% of a silicone oil which is a methyl-substituted polysiloxane having a viscosity of from 5-500 centipoises absorbed on sodium carbonate powder, said sodium carbonate being used in an amount of at least 2 parts thereof per part of silicone oil and providing said powder mixture, in 1% water solution, with an alkaline pH not in excess of 10.0.

Claim 18

Dependent Claim 86 words

An alkaline cleaning and conditioning composition for ceramic surfaces comprising an abrasive powder mixture including from 70-90% of abrasive particles, from 0.1-1.0% of a nonionic surfactant, from 1-5% of a silicone oil which is a methyl-substituted polysiloxane having a viscosity of from 5-500 centipoises absorbed on sodium carbonate powder, said sodium carbonate being used in an amount of at least 2 parts thereof per part of silicone oil and providing said powder mixture, in 1% water solution, with an alkaline pH not in excess of 10.0.

Claim 19

Dependent Claim 56 words

A cleaning and conditioning composition as recited in claim 16 in which the abrasive particles comprise a mixture of alpha quartz having a moh hardness not in excess of 7.5 and diatomaceous earth, the scratching tendency of said abrasive powder mixture being minimized by the presence of from 0.1-3% of a water soluble cellulosic film former.

Claim 20

Dependent Claim 46 words

An alkaline abrasive powder mixture comprising abrasive particles, a surfactant, a water soluble absorbent alkaline powder, and from 1-5% of a silicone oil absorbed on said water soluble alkaline powder, said composition having an alkaline pH in 1% water solution not in excess of pH 11.0.

Claim 21

Dependent Claim 46 words
