 FAQ

How often can I use the COSALU Foam Spray Gun?

You can use it as often as you wash your car, patio, or dog. Most customers use it weekly or bi‑weekly; the foam is just soapy water, so there’s no limit as long as you use a suitable soap.

Is it safe for my car’s paint and clear coat?

  1. Yes. The sprayer uses garden‑hose pressure and thick foam to loosen dirt so you scrub less, which helps reduce swirls and scratches when used with a proper car‑wash shampoo. Avoid letting foam dry in direct sun.

Can I use it to wash my dog or only my car?

  1. You can use it for both. Switch to a gentle spray mode, use a pet‑safe shampoo in the bottle, and test water pressure and temperature on a small area first so your dog is comfortable.

Do I need a pressure washer, or will a normal garden hose work?

A normal garden hose is enough. The COSALU Foam Spray Gun is designed to foam using hose pressure, so you don’t need any extra equipment or power tools.

What kind of soap should I use in the bottle?

For cars and patios, use any pH‑balanced car‑wash shampoo or outdoor cleaner that can be diluted in water. For pets, only use pet‑safe shampoo and follow the dilution instructions on the bottle.
