Method of cleaning an object

A method of cleaning an object comprising the steps of:

• (a) a step of cleaning the object with a cleaning agent containing a non-water system agent comprising an aliphatic hydrocarbon-containing cleaning agent having from 4 to 30 carbon atoms, and optionally a silicon-containing cleaning agent;
• and
• (b) a step of drying the object by use of a vapor drying treatment after it goes through the first step of cleaning,
• wherein said silicon-containing cleaning agent comprises at least one low molecular weight poly-organosiloxane selected from the group consisting of a straight chain polyorganosiloxane represented by the general formula:
• ##STR26## and a cyclic polyorganosiloxane represented by the formula:
• ##STR27## wherein R in each formula is a substituted or unsubstituted hydrocarbon group, 1 is an integer from 0 to 5, and m is an integer of from 3 to 7, and
• wherein said vapor drying treatment is conducted using a vapor cleaning agent that has a difference of solubility parameter of four or less and an evaporation latent heat of five fold or less compared with the cleaning agent.

A method of cleaning an object comprising the steps of:

• (a) a first step of cleaning the object with a cleaning agent containing a silicon-containing cleaning agent and an aliphatic hydrocarbon cleaning agent having from 4 to 30 carbon atoms;
• and
• (b) a second step of drying the object by use of a vapor drying treatment
• wherein said silicon-containing cleaning agent comprises at least one low molecular weight poly-organosiloxane selected from the group consisting of a straight chain polyorganosiloxane represented by the general formula:
• ##STR28## and a cyclic polyorganosiloxane represented by the formula:
• ##STR29## wherein R in each formula is a substituted or unsubstituted hydrocarbon group, 1 is an integer from 0 to 5, and m is an integer of from 3 to 7, and
• wherein said vapor drying treatment is conducted using a vapor cleaning agent that has a difference of solubility parameter of four or less and an evaporation latent heat of five fold or less compared with the cleaning agent.

A method of cleaning an object comprising the steps of:

• (a) a first step of cleaning the object with a cleaning agent containing one or more of a silicon-containing cleaning agent and an aliphatic hydrocarbon cleaning agent having from 4 to 30 carbon atoms;
• and
• (b) a second step of drying the drying object by use of a vapor drying treatment after it goes through the first step of cleaning,
• wherein said silicon-containing cleaning agent comprises at least one low molecular weight poly-organosiloxane selected from the group consisting of a straight chain polyorganosiloxane represented by the general formula:
• ##STR30## and a cyclic polyorganosiloxane represented by the formula:
• ##STR31## wherein R in each formula is a substituted or unsubstituted hydrocarbon group, 1 is an integer from 0 to 5, and m is an integer of from 3 to 7, and
• wherein said vapor drying treatment is conducted using a vapor cleaning agent that has a difference of solubility parameter of four or less and an evaporation latent heat of five fold or less compared with the cleaning agent.
