I use Autobrites Sparkle (glass cleaner) on all the windows and shower doors. I also use Autobrites Repel (like Rain X only better) on the shower doors. Meguirs All Purpose Cleaner on wooden floors, carpets, pvc window/door frames, wipe down of tiles in bathroom. Collinte 476 on all the tiles in the kitchen and bathroom, and the all metal handles on doors, windows and the taps in the kitchen and bathroom. Started using Autobrites Cherry Glaze to put a protective layer on the pvc doors and window frames..and it beads the water great!!!
I do all the house work, and using the car products has 2 advantages:
1. makes cleaning easier
2. justifies me spending loads on car cleaning products
