There are severe water restrictions in place here. No hoses etc. just buckets or watering cans. Consequently I have been using Meguiar's NXT detailer and NXT wax (either liquid or paste). Gives me a skin irritation but what the? The results ae good and no scratching or swirling is evident.
Meguiar's Endurance tyre gel (gloss at present because I could not get the low lustre at the time, but low lustre is available again) Smells a bit like grapes. Put on sparingly and allowed to dry. Has not given problems.
Only use a damp chamois on the interior and leather of the Crossfire but have been using Gliptone (smells OK and Ph neutral and no solvents) on the leather in the Citroen (different to the Napa leather in the Crossfire). Will give Zaino Z10 a try when I track it down locally.
Regards.
