How often do you apply your favorite interior protectant?

[Tuck91]

I usually apply once every month. My choice of interior protectant is usually Meguiars Natural Shine but now I use Meguiars Supreme Shine Protectant since it gives a great shine but no greasy feel at all.

How about you?

About once a month for me also...

I use 303, Lexol, PB B&B, Z10, Z26 and Meg`s Natural Shine. (Depending on what surface I`m applying to... )

I like to apply my favorite protectant (1Z Tienfenfleger) every month or so...

303 once a week
Z10 once a month

I use 303 about every 4-6 weeks. I`ll also use fk425, or OID from time to time.

I`m also about once a month. I wipe down the interior with a slightly damp WW MF towel after my weekly wash and that maintains the look between applications. I like the look of new, not shiny.

Leather upholstery; weekly; lightly brush surfaces, vacuum and then wipe down with distilled water on a micro fibre towel to ensure hydration.
Bi-weekly ? as above plus 303 Space Protectant for UV radiation protection

Carpets; weekly - spot clean to remove stains as necessary and vacuum
Monthly ? use hot-water extractor

Interior trim; weekly-wipe-down surfaces with distilled water dampened microfiber towel and then apply a water-based protection ( Iz einszett Cockpit Premium) plus 303 Space Protectant for UV radiation protection

Like most others, I apply a product about once a month. Usually, it`s 1Z Cockpit Premium. I try other products, too, for the fun of it.

I use Megs` Interior Quik Detailer on a regular (weekly?) basis. Every month or two I use M40 or more recently 1Z Cockpit Premium. Heck if I know what the optimal interior treatment is. I use Leather Master cleaner and protectant on my leather seats.
