To spray or not to spray?

I use Kiwi Protectall. It does not darken the vachetta and if you spray some on the canvas it doesn't show. You can buy it anywhere they sell Kiwi shoe polish. It comes in an aerosol can and costs about $8.
 
I bought a new Palermo PM & I want to protect the handles from water spots, etc. Is there anything I can use that won't ruin the light vachetta?

I use the apple garde on my artsy handle. Every few months I wipe it down with an alcohol free baby wipe,then spray it.
It didn't darken my handle.
I understand LV has said do not treat them,but I don't want my handle to turn into a dark dirty handle. ( just my personal opinion.)
