C# - ObjectContext.ExecuteStoreCommand - Clear Parameters Between Calls?

I am making multiple calls to ObjectContext.ExecuteStoreCommand with different commands and different parameters, although I use the same parameter list (object) for a several of the commands. I am getting the following exception:

System.ArgumentException: The SqlParameter is already contained by another SqlParameterCollection.

Is there a way to clear parameters between calls as I would do with straight up ADO.NET?

Updated with a code sample:

string sqlDeleteWebUserGreen = "delete WebUserGreen where WebUserId = @WebUserId";
string sqlDeleteWebUserBlue = "delete WebUserBlue where WebUserId = @WebUserId";
var argsDeleteWebUserXref = new DbParameter[] {
new SqlParameter { ParameterName = "WebUserId", Value = user.WebUserId }
rowsAffectedDeleteWebUserXref += base.context.ExecuteStoreCommand(sqlDeleteWebUserGreen, argsDeleteWebUserXref);
rowsAffectedDeleteWebUserXref += base.context.ExecuteStoreCommand(sqlDeleteWebUserBlue, argsDeleteWebUserXref);

UPDATE

Basically I am unable to find any better way of doing this, so I ended up accepting the answer below. The only difference is that I simply put the creation of the parameter into a separate method, so my calls look like base.context.ExecuteStoreCommand(sqlDeleteWebUserBlue, MethodThatWillGiveMeTheParameterArray());
