Searching for a genuine soap factory carpet shampoo can mean looking for authentic Rainbow care products, but these two formulas serve different cleaning setups. I rank Rainbow AquaMate Carpet Shampoo first for routine carpet cleaning because its dilution guidance, deodorizing benefit, and stated coverage make it the more versatile choice for compatible Rainbow shampooer systems. Rainbow Genuine Rexafoamer Shampoo is my specialist pick when dry suds are the priority, especially for upholstery or other fabrics that should not get wet.

The main decision is not simply which bottle cleans better: it is which Rainbow attachment you own and how much moisture the material can handle. AquaMate is formulated for Rainbow carpet shampooer systems; Rexafoamer is made for the Rexafoamer attachment. Neither is a general-purpose carpet soap for any machine, so buyers should check compatibility before choosing. I compare them by cleaning method, intended surfaces, dilution, and practical fit—not by treating the formulas as interchangeable.

Key Takeaways
- Best overall for compatible carpet shampooer systems: I rank AquaMate first for its approximately 500-square-foot stated coverage, adjustable dilution, and deodorizing and carpet-protection claims.
- Best for dry-suds cleaning: Rexafoamer is the more suitable choice for rugs, carpets, and upholstery when the surface should not get wet.
- Attachment compatibility decides the purchase: AquaMate is made for Rainbow carpet shampooer systems, while Rexafoamer requires the Rainbow Rexafoamer attachment.
- Both are concentrates: AquaMate specifies one capful per gallon for normal soil and two for heavy soil; Rexafoamer calls for one to two capfuls per gallon.
- Skip both if you need a cross-brand formula: Neither product is presented as compatible with carpet-cleaning machines from other manufacturers.

Rainbow AquaMate Carpet Shampoo, 16 oz
AquaMate is my lead recommendation for someone who already has a compatible Rainbow carpet shampooer system and wants a concentrate with clear guidance for both ordinary and heavier soil. The manufacturer states that a 16-ounce bottle cleans approximately 500 square feet. That figure gives buyers a useful sense of intended coverage, though actual use can vary with dilution, carpet conditions, and how the system is operated.
Its instructions call for one capful per gallon of water for normal soil and two for heavy soil, giving the buyer a straightforward way to adjust the mix. The product is also described as deodorizing and helping protect carpets, benefits not listed for Rexafoamer. That makes AquaMate the more complete routine-carpet option in this pair, while Rexafoamer is better defined by its dry-suds approach and suitability for materials that should not get wet.
The tradeoff is a firm system boundary: AquaMate is formulated for Rainbow carpet shampooer systems, not presented as a universal carpet solution. If you need dry-suds treatment for moisture-sensitive upholstery, choose Rexafoamer instead—but only if you have its matching attachment. Buyers without either compatible setup should skip both rather than assuming a concentrated shampoo will work in another machine. I would also follow the carpet’s care instructions and the system manual, since the product details do not specify suitability for every fiber.
Pros:- Stated coverage of approximately 500 square feet per 16-ounce bottle
- One- and two-capful dilution guidance for normal and heavy soil
- Deodorizes and is described as helping protect carpets
- Concentrated formula for compatible Rainbow shampooer systems
Cons:- Designed for Rainbow carpet shampooer systems, limiting use with other brands
- The approximate coverage is not a guarantee for every carpet or cleaning setup
- Not identified as the dry-suds option for upholstery or fabrics that should not get wet
Best for: Rainbow system owners who want a concentrated carpet shampoo with normal- and heavy-soil dilution guidance, stated coverage, and deodorizing support.
Not ideal for: People using another brand’s carpet machine, shoppers seeking a dry-suds upholstery formula, or anyone whose carpet-care instructions do not allow the intended cleaning method.
- Brand:Rainbow
- Product type:Concentrated carpet shampoo
- Volume:16 oz
- Stated coverage:Approximately 500 sq ft per bottle
- Compatibility:Rainbow vacuum carpet shampooer systems
- Normal-soil dilution:1 capful per gallon of water
- Heavy-soil dilution:2 capfuls per gallon of water
- Additional stated functions:Deodorizes and helps protect carpets
Our verdict“I rank AquaMate first for compatible Rainbow carpet shampooer owners who want clear dilution choices and stated coverage, but not for cross-brand or dry-suds use.”
Rainbow Genuine Rexafoamer Shampoo
Rexafoamer earns the specialist slot because its dry-suds method addresses a different cleaning concern from AquaMate: managing moisture on fabrics. It is intended for rugs, carpets, and upholstery, and its description specifically includes furniture the manufacturer advises should not get wet. For those jobs, a dry-suds formula is the more relevant match than AquaMate, whose supplied details describe it as a carpet shampoo for Rainbow shampooer systems.
The concentrate is mixed at one to two capfuls per gallon of water, and the dry suds are designed to remove traffic film. That gives Rexafoamer a focused role for maintenance cleaning when the surface or care guidance calls for avoiding a wet-cleaning approach. Compared with AquaMate, though, it has no stated square-foot coverage, no separate normal- and heavy-soil directions, and no listed deodorizing or carpet-protection claim. Its appeal rests on the cleaning method and surface fit, not broader documented benefits.
Attachment compatibility is the deciding drawback. This shampoo is made only for the Rainbow Rexafoamer attachment, so owning a Rainbow system alone should not be treated as proof that it fits your setup. AquaMate is the more sensible pick for a compatible Rainbow carpet shampooer when routine carpet coverage is the goal; Rexafoamer makes more sense for the matching attachment and a dry-suds use case. If you do not own that attachment, or if the item’s care label calls for another method, I would pass on this bottle.
Pros:- Dry-suds approach for cleaning traffic film
- Designed for rugs, carpets, and upholstery
- Can suit furniture the manufacturer advises should not get wet
- Concentrated dilution of one to two capfuls per gallon
Cons:- Made only for use with the Rainbow Rexafoamer attachment
- No square-foot coverage figure is provided
- No deodorizing or carpet-protection function is listed in the supplied details
Best for: Owners of the Rainbow Rexafoamer attachment who need a concentrated dry-suds shampoo for rugs, carpets, or upholstery that should not get wet.
Not ideal for: Buyers without the Rexafoamer attachment, people seeking stated per-bottle coverage or deodorizing claims, and anyone looking for a shampoo compatible with multiple brands.
- Product type:Dry-suds shampoo concentrate
- Compatible attachment:Rainbow Rexafoamer
- Dilution:1–2 capfuls per gallon (3.8 L) of water
- Intended surfaces:Rugs, carpets, and upholstery
- Cleaning purpose:Designed to remove traffic film
- Cleaning method:Dry suds
- Moisture-sensitive use:Can be used on furniture the manufacturer advises should not get wet
Our verdict“I recommend Rexafoamer over AquaMate when dry suds and the matching attachment are the priority, but its narrow compatibility makes it a poor general-purpose choice.”
How We Picked
I treated genuine soap factory carpet as a search for authentic Rainbow carpet-care products and compared the two supplied options against the job each is designed to do. My ranking reflects practical fit rather than a claim that one formula is universally superior. AquaMate takes the overall position because its stated coverage, two soil-level dilution instructions, and added deodorizing and carpet-protection functions make its use case clearer for routine carpet cleaning with a compatible Rainbow system. Rexafoamer earns a distinct specialist role for dry-suds cleaning, including upholstery and fabrics the manufacturer advises should not get wet.
I also weighed system compatibility, intended surfaces, concentration, and the kind of cleaning method a buyer is choosing. A concentrated formula can be useful, but it does not make a product suitable for an unlisted attachment or machine. The supplied product details do not establish ingredient contents, independent performance results, drying times, or compatibility with specific carpet fibers. I do not infer those details. Before use, I would follow the product and machine instructions and check care guidance for the surface being cleaned.

Factors to Consider When Choosing Genuine Soap Factory Carpet
I would choose between these products by matching the formula to the cleaning attachment and the surface, rather than buying on the word “shampoo” alone. Both are concentrated Rainbow products, but their intended equipment and cleaning approach are different.
Start with the attachment you own
This is the fastest way to narrow the choice. AquaMate is formulated for Rainbow vacuum carpet shampooer systems; Rexafoamer is made for the Rainbow Rexafoamer attachment. The supplied descriptions do not support treating either as compatible with every Rainbow machine, let alone other brands. Check your system instructions for the precise attachment and product fit before mixing a solution. If neither product matches your equipment, neither is a safe substitute simply because both carry the Rainbow name.
Match the cleaning method to the material
Rexafoamer’s dry-suds cleaning is the key differentiator for upholstery and furniture that the manufacturer advises should not get wet. It is also intended for rugs and carpets. AquaMate is positioned as a carpet shampoo for its compatible systems and adds deodorizing and carpet-protection claims. Follow the surface’s care label and the equipment manual: the product descriptions do not establish that either formula is right for every fiber, backing, or upholstery fabric.
Read dilution and coverage as guidance
AquaMate gives separate directions for normal soil and heavy soil: one capful per gallon of water or two, respectively. It also states approximate coverage of 500 square feet per 16-ounce bottle. Rexafoamer’s range is one to two capfuls per gallon, without a stated coverage figure. Those details make AquaMate easier to plan around, but the coverage is approximate; the amount used can depend on the surface, soil, and cleaning process. Follow the product label rather than stretching or strengthening the mix beyond its directions.
Know what the product details do not establish
These descriptions do not provide ingredient lists, drying-time estimates, independent cleaning comparisons, or confirmed suitability for named carpet fibers. I would not infer hypoallergenic status, residue behavior, or stain-removal results from the word “concentrated.” If a carpet or piece of furniture has special care requirements, check its instructions and the shampoo label first. For moisture-sensitive furniture, Rexafoamer is the listed dry-suds option, but its use still depends on the manufacturer’s directions and the correct attachment.
Pick by job, not by broad claims
For routine carpet cleaning with a compatible Rainbow shampooer, AquaMate is the more rounded choice in this lineup because it lists coverage, soil-based dilution, deodorizing, and carpet-protection functions. For dry-suds treatment with a Rexafoamer attachment, Rexafoamer is the more targeted choice, especially for eligible upholstery. If your priority is an all-brand formula, neither product fits the information supplied. That distinction is more useful than treating one bottle as an across-the-board winner.
Frequently Asked Questions
Which of these is the better general carpet shampoo?
I rank AquaMate as the better fit for routine carpet cleaning when you own a compatible Rainbow carpet shampooer system. It provides dilution directions for normal and heavy soil, states approximate coverage, and is described as deodorizing and helping protect carpets. That does not make it universal: Rexafoamer may be the better match for dry-suds cleaning, and both products have specific equipment requirements.
Can I use AquaMate with the Rainbow Rexafoamer attachment?
The supplied details identify AquaMate for Rainbow vacuum carpet shampooer systems, while Rexafoamer Shampoo is specifically made for the Rainbow Rexafoamer attachment. They do not confirm that AquaMate is suitable for that attachment. I would check the equipment manual and product label instead of assuming the two formulas are interchangeable.
Which product is intended for upholstery that should not get wet?
Rexafoamer uses dry suds and is described as suitable for furniture the manufacturer advises should not get wet. It is still restricted to the Rainbow Rexafoamer attachment. Check the furniture’s care directions and the shampoo instructions before cleaning; the description does not establish suitability for every upholstery fabric.
How much AquaMate should I mix for a gallon of water?
The supplied directions call for one capful per gallon for normal soil and two capfuls per gallon for heavy soil. The bottle is stated to cover approximately 500 square feet, but that is an estimate rather than a guaranteed result for every carpet or machine. Follow the label and Rainbow system instructions for your cleaning session.
Are either of these shampoos suitable for non-Rainbow machines?
The product information does not establish compatibility with other brands. AquaMate is designed for Rainbow carpet shampooer systems, and Rexafoamer is made only for the Rainbow Rexafoamer attachment. If your equipment is from another manufacturer, I would choose a formula expressly approved for that machine rather than risk using an unlisted product.
Conclusion
For Rainbow carpet shampooer owners looking for one straightforward carpet-care pick, I recommend AquaMate: its approximate coverage, two soil-level dilution directions, and deodorizing and carpet-protection claims make it the more versatile option here. Choose Rexafoamer if you own its specific attachment and need dry-suds cleaning for rugs, carpets, or eligible upholstery that should not get wet. If you use another brand’s machine, lack the required Rainbow attachment, or cannot confirm that the formula suits your surface, skip both and look for a product approved for your equipment and material.
