How to Clean Your 4WD or Off-Road Vehicle Like a Pro
Whether you’ve just hit the beach or tackled some muddy tracks, a proper clean is essential to keep your rig looking mint and running right.
Forget the garden hose and those try-hard foam cannons that spew more water than foam (you know the ones — where the suds slide straight off before they’ve even done their job). And don’t get us started on over-powered pressure washers designed for blahsting your paint off.
BLAHST gear is made for the job — dialled-in pressure, proper foam coverage, and smart tools to get the gunk gone without the damage.

Step-by-Step Cleaning Guide
Underbody Pre-Wash
Fill your BLAHST foam cannon with BLAHST Salt Removal Wash and cover the entire vehicle in thick foam. Let it sit for 2 minutes to break down grime- don’t let it dry.

Underbody Cleaner
Clip the Underbody Cleaner onto the R18 and blast away mud, sand, and salt from underneath. Do this before washing the rest of the vehicle so you're not flicking grime back onto clean panels later.
Pre-Rinse the Exterior
Use the R18 to knock off loose dirt and debris. Work from the roof down, and avoid blasting seals, vents, or electricals directly.
Foam It Up
Fill your BLAHST foam cannon with BLAHST Foam Wash or Salt Removal Wash and cover the entire vehicle in thick foam. Let it sit for 1–2 minutes to break down grime—don’t let it dry.
Hand Wash with Two-Bucket Method
Use a soft clean wash mitt or microfibre towel to gently agitate dirt on high-contact zones like doors, guards, mirrors, and rear panels. Rinse your mitt regularly using the two-bucket method.
Final Rinse
Hit the vehicle again with the R18 to wash away all remaining foam and dirt.
Dry with the Air Maxx
Use the Air Maxx Blower Dryer for a contactless dry. It’s perfect for crevices, badges, mirrors, door handles, and roof racks—plus no swirl marks or towel drag.
Pro Detailer Tip
After drying, finish with BLAHST Ceramic Spray Coating. It boosts gloss, repels water and dirt, and makes your next wash quicker and easier.
Things to Avoid
❌ Don’t use high pressure directly on sensors, seals, or under the bonnet.
❌ Don’t let foam dry on the paint.
❌ Don’t towel dry a dirty surface.
