How often do i clean my car ?
I enjoy spending time cleaning my roc,as a rule i clean him once a week without fail,thats a full wash, dry and vac and a quick detail to the tyres and plastic wheel arch liners,takes about a hour and a half.Then about once a month he gets a coat of wax,collinite is my preferred winter wax.Then once every 6 months he will get a full detail,snow foam,wash,clay,machine polish to remove all swirll marks then a layer of polish then a layer of sealant and top it all off with a layer or two of wax.Over the years i have used many cleaning products but i find the following very good and easy to use without breaking the bank,i know cleaning products are a personal thing so i dont expect all to agree on my actual prefered range.
Shampoo, chemical guys citrus wash and gloss(1 gallon £25ish)
Polish,sonus sfx 1(£9ish)
Sealant,poorboys exp (£12ish)
Wax,collinite 476s(£16ish)
Tyers,chemical guys new look trim gel(£11ish)
Alloys,poorboys wheel sealant(£13ish)Note i never use alloy cleaner i prefer to use just bodywork shampoo
Under carrage,chemical guys, bare bones(£9ish)
interior,damp cloth(free)or poorboys natural look dressing(£9ish)
now can we please have a cleaning and detailing section
sponges
. here is a little shopping list that every rocco owner should have at the very least.
The only place where i differ from the above is that i wont be using a polish for at least twelve months on the Roc. My understanding is that most Polish products contain an abrasive, some harsh and others not but generally they take off microscopic layers of paint each time you use them as this is how they renew the look of the paint. Whilst my paintwork is still fresh and tar free i am simply washing the car and adding a layer of good quality wax. There are lots of very good polish / wax products on the market, i have gone with a new one from Autoglym (HD Wax). If you are not happy with the dealer prep or find you are picking up lots of tar spots then obviously wax isn't the solution. One of the specialist Tar products is probably best, then polish the car first then apply a layer of wax. Depending upon the wax top up as required. Generally i find Meguiars / Autoglym products towards the top end in terms of performance but not too hard on the wallet. Money no object i would probably go for Zymol or poorboys etc.. Washing you car properly doesn't take long using the right technique and products. It would be good to have some detailed info in the Roccopedia on cleaning, specific to the Roc. I would be happy to contribute along with other members if we think it's a worthwhile addition. 
I bet it does scratch, your colour just won't show it up so easily.
