That would be a huge and confusing list as everyone has their favorites for each category. If I were to start a general list it would go like this:
-decon wash
-clay (fine, medium, etc)
-iron & tar remover
-compound
-medium polish
-finishing polish
-paint sealant/coating
-quick detailers/drying aides (spray wax)
-metal cleaner/polish/hi-temp sealant (chrome, etc.)
-leather cleaner
-upholstery cleaner
-leather conditioner/protectant
-upholstery protectant
-all purpose cleaner
-glass cleaner
-trim sealant
-tire dressing
-undercarriage dressing
-rinseless wash
-2BM car wash shampoo
-various MF (mitts, towels, etc.)
-paste wax
-plastic UV sealant for headlights, tail lights, etc
hard goods:
-machine buffer
-pads for machine buffer
-spray bottles & trigger sprayers
-foam hand applicators
-MF hand applicators
-air dryer (metro blaster, sidekick, etc)
-buckets and grit guards
-foamer
-extractor for carpets/upholstery
-funnels/measuring cups
I'm sure I missed some things, but hope this helps you find some categories you might be missing.
