Ultimate guide to keeping your car pristine, inside and out!
Washing your car at home sounds simple — until you ruin your paint, strip your ceramic, or blast water into places it shouldn't be. That’s why we built the BLAHST R18 Wall-Mounted Retractable Pressure Washer, Air Maxx Blower Dryer, and K21 Wall-Mounted Vacuum — the ultimate setup for safe, satisfying car care.

Step-by-Step Cleaning Guide
Vacuum First with the K21
Start by removing loose dirt, leaves, sand and crumbs from your interior. The K21’s powerful suction and long, retractable hose make it easy to get into footwells, between seats, and across boot space — all without dragging around a bulky shop vac.

Pre-Rinse with the R18
Pull out the R18’s hose, lock it in place, and rinse from the roof down to knock off surface dust and grime.
Pro Tip: Stay 50–70cm back to protect trims, seals, and soft paint.
Foam It Up
Load your foam cannon with BLAHST Foam Wash and coat the car. Let it dwell for a few minutes (but don’t let it dry) — this softens dirt before hand washing.
Hand Wash with Two-Bucket Method
Use your microfibre mitt and the classic two-bucket method: one for suds, one to rinse. Work top to bottom, rinsing your mitt between panels.
Final Rinse
Rinse off remaining suds with the R18. Controlled pressure means zero damage to coatings or trims — and the retractable hose keeps things tidy.
Dry with the Air Maxx
Forget towels. The Air Maxx blasts warm, filtered air into door jams, badges, wheels and grills. Touchless = streak-free = no swirls.
Pro Detailer Tip
Finish with BLAHST Ceramic Spray Coating — adds gloss, slickness, and water-beading protection. Keeps your car cleaner for longer, and easier to wash next time.
Things to Avoid
❌ Don’t use max pressure on window seals, electronics, or under the bonnet.
❌ Don’t let foam dry on paint.
❌ Don’t use dirty towels or old chamois (they scratch!)
Keeping your gear clean
Pressure washer accessories for car detailing: which ones matter?
Two accessories do most of the work in a car detailing setup: a foam cannon for the contact-free pre-wash, and a 25 or 40 degree nozzle for the rinse.
Which foam wash solution makes thick, safe snow foam?
A pH neutral car wash concentrate made for a foam cannon, mixed at the ratio on its label and run through a cannon on a pressure washer.
How to store a pressure washer between washes
Store a pressure washer with the pressure released, the water out of the pump and hose, the detergent line flushed, and the hose put away without kinks in a dry spot.
