Introducing 2 new guinea pigs

Question
This is kind of a follow-up question to a previous question I asked, but the forum said that I had followed-up too many times and that I needed to ask a new questions lol.  I am doing the switching-sides thing you recommended for my new 2 new guinea pigs.  I just had two quick questions about what you told me:
1) after the 2 weeks are up and I am going to clean the cage and remove the partition in the guinea pigs' cage, is it ok if I leave the same wooden houses in there or will the smells bother them?

2)  Where do I bathe the guinea pigs?

Thank you!!!!

Answer
well people say you should wash the objects too, i personally do not bother but if your piggies were particularly agressive to one another then i would wash them with the same solution that you washed the rest of the cage or hutch in.

as for where to wash them its your choice, most people use a bath or sink with just a little water in (dont let the water go as high as their heads). but as mine are outdoor i have a plant trough thats empty and just it with water, so long as the waters luke warm or slightly warmer than luke warm and is no higher than their shoulders it will be fine
