Step-by-Step Setup Guide

1. Pick the Right Location

Look for:

Shade (avoids water spots from sun-drying)
Flat surface (prevents runoff from pooling)
Nearby hose access

If you’re in an apartment, a self-service coin wash bay works—just bring your own tools and soap.

2. Use the Two-Bucket Method

This method minimizes swirl marks:

One bucket: clean water for rinsing mitt
One bucket: soapy water for washing

Dunk your mitt in the soap bucket, wash a section, then rinse it in the clean water bucket before reloading.

3. Work Top to Bottom

Start from the roof and work down. Why?

Lower panels are the dirtiest
Prevents dragging dirt and debris across clean areas

Use separate mitts or cloths for wheels and tires to avoid cross-contamination.

4. Dry Immediately with Microfiber Towels

Leaving water to dry naturally = water spots.

Use clean, soft microfiber towels
Dab and drag gently—don’t rub hard
Wring out towels frequently if doing a full-size SUV or truck

5. Add Finishing Touches

Apply spray wax or quick detailer while the surface is still slightly damp. This:

Enhances shine
Adds water beading protection
Keeps your car cleaner between washes

Finish with tire shine to make the rubber pop and your car look professionally done.

Add-On Ideas (Still Budget-Friendly)

If you want to go the extra mile:

Foam Cannon Attachment (for hose or pressure washer): $20–$30
Clay Bar Kit: Great for older or neglected paint: ~$15
Detailing Stool or Rolling Bucket Dolly: Saves your back during wheels: $20–$30

Common Mistakes to Avoid

Using dish soap – It strips wax and dries out trim.
Reusing dirty towels – Can cause scratches.
Skipping the rinse bucket – Increases swirl risk.
Washing in direct sun – Leads to quick drying and spots.
