Abstract:
A method of removing residue containing an insoluble lithium phosphate compound from a surface includes soaking the surface in a cleaning aqueous solution having a pH less than 5 for a select time period, whereby the insoluble lithium phosphate compound is converted into soluble lithium hydrogen phosphate and the soluble lithium hydrogen phosphate is dissolved in the cleaning aqueous solution. The method includes rinsing the surface with deionized water. The surface is substantially free of the insoluble lithium phosphate compound after the rinsing.

Claim (Index 13):
A method of preparing strengthened glass or glass-ceramic, comprising:\n heating a salt bath comprising a phosphate salt and at least one source of alkali metal cations to a temperature greater than 360\u00b0 C.; contacting at least a portion of an ion-exchangeable substrate comprising lithium cations with the salt bath, whereby at least a portion of the lithium cations diffuse from the ion-exchangeable substrate into the salt bath and are dissolved in the salt bath; selectively precipitating the dissolved lithium cations from the salt bath to form at least one insoluble lithium phosphate compound, wherein a portion of the at least one insoluble lithium phosphate compound is deposited on a surface of the ion-exchangeable substrate; removing the ion-exchangeable substrate from the salt bath and soaking the surface in a cleaning aqueous solution having a pH less than 5 for a select time period, whereby the at least one insoluble lithium phosphate compound on the surface is converted into soluble lithium hydrogen phosphate and the soluble lithium hydrogen phosphate is dissolved in the cleaning aqueous solution; and rinsing the surface.
