Black Friday early access: FREE spray bottle with the Hydro Free Spray Bundle
Same driveway, same Sunday. Just no more kneeling on wet concrete, lugging buckets about, or a stiff back on Monday morning.

You know the routine. Fill the bucket, carry it out, bend down, dunk the sponge, stretch over the bonnet. Get down on your knees for the wheels. Stand back up a little slower than you used to.
The car looks decent afterwards. Your back, knees and hands feel like you've done a shift.
And paying some lad a tenner at the car wash? Not a chance. You'd rather it was done properly. Good news: you don't have to choose between your back and your standards. Here's why thousands of drivers have changed how they wash.
Ten litres of water weighs around 10kg. Most of us lift it, carry it, lower it and refill it more than once a wash, usually twisting as we go. With Hydro there's no bucket at all. One bottle, carried in one hand.
Wheels, sills and the bottom of the doors hold the worst road muck. That's exactly where the bucket and sponge keeps you crouched or kneeling the longest. Hydro's spray bottle reaches the low panels while you stand.
Professional detailers stopped scrubbing years ago. They spray a pre wash and a thick snow foam on first, leave it a few minutes, and let it loosen the dirt before anything touches the paint. Most of the grime just rinses away. Hydro gives you that same method at home.
Step 1
Give the bottle 10 to 15 pumps and spray the whole car, wheels and lower panels first.
Step 2
Pick up the second bottle and coat the car in thick foam. Leave it a few minutes. Put the kettle on.
Step 3
Rinse it off with whatever you've got and give it a light wipe. Nothing left to scrub.
Tip from customers: give the bottle a few extra pumps halfway round the car. It keeps the foam thick right to the end.
A sponge picks up grit and drags it across the paint. So you press harder, for longer, and end up putting fine scratches into the car you're trying to look after. Hydro lifts the dirt off first, so you're not grinding it in.
Thick foam used to mean a pressure washer, a foam lance, extension leads and hoses everywhere. Hydro's bottle is pump-up, so there's nothing to plug in. And compared with a tenner at the car wash every fortnight, well over £250 a year, it pays for itself fast. Plus nobody's using the same dirty mitt from the car in front on yours.

"I bought the hydro spray bottle as have no access to a hose. Was worried it was a bit of an insta gimmick. I was WRONG! I could not imagine cleaning the car without it now."
"It produces lovely thick foam very easily and makes cleaning my car so much easier."
"I've always been the type of person who power washes a car off and thought it's been good enough... The car is easy to clean and comes up really well. People have commented on how good it looks."
"Easy to put on, so easy to take off. Brilliant smooth glossy finish."
No. The Hydro bottle is pump-up, so there's nothing to plug in and no hose needed to make the foam.
The Pre Wash goes on first to break down road film and grime, then the Snow Foam lifts it off. If the car's caked in mud, rinse the worst off before you start.
Yes. It's made to be safe on all vehicles and surfaces, and lifting the dirt before you wipe means less grit dragged across the paint.
One for Pre Wash, one for Snow Foam, so there's no rinsing out and refilling halfway round the car. During Black Friday the second bottle is free.
You've got 30 days. Not happy, send it back for your money back.
Yes. Customers use it on bikes, motorbikes and caravans too.
