Query: Silicone Spray

We've used this litterbox for more than 3 years now. We have 2 cats that are quite competetive in their box activities. I agree with many of the reviews...the litter does clump at times and then the rake is unable to complete its sweep of the pan. We currently use Fresh Step (we've tried them all). I hose the litter pan and rake down every month or so and when its dry, I spray it with 2 coats of SILICONE SPRAY to decrease muddy litter patches. !!Spray anything that touches the litter!!I hate cleaning the litter box, but partial scooping every 1-2 days is better than daily changes, any day of the week. Enjoy! P.S. Have you seen the power booster cable advertised to give the rake a li'l ooomph?
