Car Wash Prep: Setting Up Your Tools and Work Area

Choose suitable working area such as your driveway, away from other cars and preferably not under direct sunlight as premature drying can leave spots. Ensure surfaces are not hot to touch before working.

Assemble Otto Guys Foam Cannon by filling two ounces of Otto Guys Pure Wash into the bottle and adding 20 oz of clean water. Holding onto the lid, screw onto the bottle securely. Give the mixture a swirl and set aside.

Fill the 5 gallon buckets with clean water. Insert Otto Guys Bucket Insert Grit Traps. One bucket will be designated as the Rinse bucket and the other will be the Wash bucket. Add 1-2 oz Pure Wash into the Wash bucket, agitate to create foam and set aside.

Connect hoses and gun to pressure washer, plug to power, turn on water supply and pressure washer, and test to make sure everything works.

Note: when connecting a nozzle to the pressure washer gun, test fire AWAY from the vehicle body to confirm it is securely attached.

How to Wash Your Car at Home: Full Step-By-Step Guide

Wheels First! Why? Inevitably cleaning the dirtiest part of car will create splatter and can impact other areas. By cleaning the paint after you ensure the most delicate parts of your ride stays the freshest.

Connect Foam Cannon to gun and saturate wheel, tire, and wheelwell. Scrub the tire sidewall vigorously with a Tire Brush. The agitation will lift dirt, grime, and tire bloom (the brown stuff) off the sidewall and prepare the surface for proper rubber care later.

Next take the Otto Guys Microfiber Pro or Otto Guys Premium Wheel Brush to tackle the wheel faces, spokes, and barrels, making sure the brushes are rinsed regularly.

Connect the appropriate spray nozzle to gun, test fire AWAY from the car, and rinse the wheel, tire, and wheelwell thoroughly. Tackle the remaining wheels one by one.

After the Wheels then Paint!

Pre Wash. Prewashing is beneficial as it helps remove loose dirt, dust, and debris before the start the actual washing process. By removing the initial layer of contaminants, I reduce the risk of scratching the paint during the subsequent process.

Use the Foam Cannon to apply a thick layer of Pure Wash foam onto entire vehicle surface. Let the foam dwell for a few minutes before rinsing. Pure Wash will encapsulate, lift the loose dirt off the paint and slowly carry it down. While waiting, go back to the Wash bucket and agitate the solution to create a foamy mixture. Back to the car - don’t let the solution dry - Attach spray nozzle to gun, test fire AWAY from car, and rinse off the foam.

Second Foaming. Reapply as per previous step.

Hand Washing. Dip Otto Guys Microfiber Wash Mitt into the Wash bucket, pick up a fresh helping of shampoo in the wash mitt, and wipe the vehicle starting from the higher surfaces and working my way around the car and down to the lower panels. The Wash Mitt is double sided so I flip to the fresh side at the start of each panel before going back to the buckets to reload.

Reloading. Why do I like using Grit Traps? These add a layer of defense by allowing dirt particles to fall through and away from the wash solution. It reduces the likelihood of dirt particles suspended in the wash solution getting picked up again by the Wash Mitt and scratching the paint. Go to the Rinse bucket and agitate the Wash Mitt in the water, scrubbing both sides into the Grit Trap to release the dirt before moving to the Wash bucket to pick up fresh solution then continue working around the car.

Final Rinse. Connect spray nozzle to gun, test fire AWAY from the car. Give all surfaces a thorough rinse to ensure all traces of the shampoo is removed.

Dry. Use Otto Guys Premium Drying Towel to make quick work of drying the car. The 1200 gsm, twist loop fiber, large towel is extra absorbent and wicks up a tremendous amount of water from the vehicle surfaces without the need for rubbing, ensuring quick and efficient drying without scratching.

Finishing Touches. Otto Guys SiO2 Shield is a fantastic way of enhancing your vehicle’s gloss and adding protection between washes. I use this ceramic sealant sparingly, one to two sprays per panel, coupled with Detailing Towels to spread and buff off. I then use SiO2 TIRE Matte together with an Applicator to apply a layer of tire dressing to the tire sidewalls.

Enjoy the fruits of your labor!
