the problem is well especially in reading, is that the water is so hard.

I've found a decent shampoo makes all the difference too and the best I've used to date is Duragloss 901 doesn't leave any streaks or water marks and once the car has been washed I find using an open ended hose or water through a watering can sheets water off the car rather than letting it sit on flat panels.

then using a decent quick detailer like meguiars last touch or optimum instant detailer followed by a gentle buff with a flush microfibre should leave you without any watermarks.

this is all based on the cars paintwork being properly prepped and protected with a wax or sealant.

x2 on sheeting the water off saves so much time i can dry the whole in minutes with one drying towel and as said above a well prepped car is so easy to clean.

tried the duragloss 901 shampoo today.
first impressions, very good.
leaves a nice finish as in no watermarks.
dried off with a microfiber towel.

Another vote for rainwater here. Rinse car off with watering can (rose taken off) spray on some QD which disperses water a d it'll be practically dry already. Quick pat down with mf cloth and I'm done.

No sand or nasties because the tap is 6" above the invert which acts as a grit sump - like a roadside catchpit. I use the same water for flowers in vases and its as clear as tap water.

Micro fibre cloths whilst the car is still wet
Buy in bulk from car shows or when on offer

An in-line scale reducer on you’re outside tap will help no end.

Old post I know but for anyone with a similar problem, spray the following onto a wet car GYEON Q²M WETCOAT rinse of and start drying. You won't have any watermarks, but you will have an extremely hydrophobic coating that will be as glossy and smooth as a good quality wax. £10 for 500ml. 'Tis quality stuff.

I use a DI vessel, one of these :

I just rinse the car and walk away. Dries without watermarks even in direct summer sunlight. No physical drying, so no (additional) risk of swirls using microfibre cloths that could be old or grab dirt from panel gaps or bits you’ve missed. The sand does need replaced, depends how often you use it and age, I maybe change mine every 4/5 months but then I don’t wash the car every weekend. Bonus - you can also use it for washing / rinsing windows without the need to dry either.

You also need a TDS meter to measure how effective the sand is occasionally as it starts to leave spots at about 7-10 ppm, so that’s when to change it : https://www.cleaningspot.co.uk/acatalog ... tml#SID=16

Finally one of these for refilling : https://www.cleaningspot.co.uk/acatalog ... tml#SID=29

Refill sand bags, 25 litre so good for 3.5 fills, £70 : https://www.cleaningspot.co.uk/acatalog ... tml#SID=29. Currently lasting me nearly a year.

+1

I use sonax brilliant shine detailer.

Lots of recommendations on detailing world about it. Classed as a quick detailer but actually acts like a wax. Since using it after every 2/3 washes, My car constantly beads and no water marks left behind.

I usually wash car. Run a hose over all the panels after tidying away pressure washer to drain water off the panel, Then drying towel. Seems perfect everytime. Every couple washes Il go round with sonax BSD and that keeps it going.

Another +1 for Sonax BSD from me also. I've been using this for a couple of years now and it's by far the best quick detailer I've come across. Easy to use, deepy glossy shine and amazing water beading that lasts for weeks. I buy it in 5 litres and it works out much cheaper. Just seen it on EBay for £38.95 delivered

I think 5litres might last to the end of time ha.

I was using the normal bottle and im not even half way through.

I use very little as its very sticky and hard to buff off if i use too much.
