A cost effective, eco-green and simple way to clean mirrors and windows is to use club soda (Just cheap plain club soda). Put some undiluted club soda into a clean spray bottle. Spray onto window or glass to be cleaned and then wipe well with a clean cloth, finishing with a clean dry cloth to get a spotless shine (try and use microfiber cloths for this task).
It is a good maintenance idea to clean the inside of the dishwasher to avoid scale and clogging. Do so by pouring some white distilled vinegar in the bottom of the dishwasher (also, put some in the rinse aid dispenser). Run a regular cycle and afterwards, wipe down all surfaces inside and out (White vinegar helps to remove hard water deposits inside the dishwasher).
If you are dealing with clogged drains over and over again, Alka Seltzer and vinegar can usually fix the problem. First, place two Alka-Seltzer tablets into the clogged drain and then pour one cup of vinegar down the drain. After ten minutes, run hot water down the drain. Your drain should be free of clogs (You could also replace the Alka Seltzer with baking soda).
To clean window tracks, mix dish-washing liquid and warm water together. Dip a soft toothbrush in the mixture and clean the tracks. Q-tips can be used to get into those hard to reach corners. Lastly, dry the window tracks. Then apply a light coat of mineral oil to the tracks using a cotton ball
To clean that nasty grout, all you need is hydrogen peroxide and the all-mighty baking soda. Make a paste out of them and apply it to your grout with a toothbrush. Allow the mixed paste to sit for one hour before removing (If you feel that the grout is somewhat unsanitary, rub bleach on your grout with a toothbrush)
