I normally work on Saturdays.
I came back for lunch. After lunch, I cleaned the air conditioners of our apartment.
First, I took off filters. I washed them in the bathroom, and kept them being dried.
Then I used the cleaning sprays Katya had bought the other day. I sprayed the mist inside the air conditioners to have the dirt dissorved out.
I came back home for dinner. I put the filters in. Now the air conditioners are ready.
They are not plugged in yet. We will go with the electric fans until it gets very hot.
