User questions & answers

Question:	Can I used on the underbody of the car
Answer:	It is based on the capacity of your cooling system. If your system is 12qts and lower, one bottle will do. If your system is over that then you will need two bottles.
Question:	will this remove plasti dip
Answer:	Yes you can!
Question:	Would this be safe to clean the chain and gears on my bike without hurting the carbon frame
Answer:	They list a "Heavy Duty Clean" where you leave the product in for 3 to 6 hours of normal driving over a "few" days. I read that as daily drive it for 1 to 2 hours a day for 3 days. Then they say to drain it. I can't say if it will be destructive if it's in there for a week, but I have commuted with it in my truck for the three days and dumped it and it worked fine.
Question:	Is this small bottle a concemtrate or is it ready to use
Answer:	It doesn't confirm if it's ok or not for dexcool systems on the bottle, itself. However, I have used it to flush my 2000 Sierra without any issues. As long as you thoroughly flush your system with water after you run the cleaner in it, it should be fine.

User questions & answers

Question:	Can I use this on bike chains? or plastic parts
Answer:	I purchased to help clean auto engine oil and grease and as you know there is plastic under the hoods of most cars and there was no damage and I don't see how it could hurt bike chains, it did a fair job, may take several applications, hope this helps.
Question:	Would it work for degreasing parts for spray painting
Answer:	Depends how greasy your parts are. Not the best degreaser I have found.
Question:	would it work for cleaning exhaust tips
Answer:	Dont see why not, as long as they arent hot.
Question:	Is this effective at cleaning a car's dirty and grimy underbody
Answer:	NO! For all that it's supposed to be it doesn't do the job. For general cleaning it has to sit for a longer period of time vs other well known engine cleaners and the like, yet while not have as good an outcome. Buy another cleaner.

User questions & answers

Question:	can i use this as a quick wipe down? just spray it on and wipe it down when water source is not always available
Answer:	Probably. I’d test a small area first. The concern is that without water, residue may be left on which will stink up the passenger area when the engine gets hot.
Question:	Is it safe on electrical components? And battery
Answer:	I've used it on everything in my Camaro, just have a hose with decent psi rating in it handy to spray away anything left, it's not good to leave it under there while motor gets hot again.
Question:	Is it fine if I just clean my engine with this product while the engine is in the car
Answer:	Yes you can. Follow the directions on the can.
Question:	Will this damage chromed items
Answer:	Not quality chrome. Cheap imitation chrome may or may not. Off the store shelf degreaser is mild. They discontinued a stronger version a few years back andy's did not mess up chrome. You need to take care around plastic, alternator and rubber. That's with any cleaner.

User questions & answers

Question:	will this stuff work on clothes in the washer
Answer:	This product works best on organic soils, and red clay is a mineral stain. It won't harm the stone, but I recommend using it stronger than label instructions. Using a pump-up, garden-style sprayer, mix Oxysolve 50/50 with water. Apply to a section of the stone and scrub with a non-metallic deck brush. Rinse before the cleaning solution has a chance to dry, or it will be more difficult to remove. IF the stain is lightened, but not completely gone, reapply the same way.
Question:	Anyone tried this on sealed asphalt oil stains
Answer:	Thanks for the question... If your walls are concrete or block/brick or some other typical exterior wall surface, you can use the Concrete and Driveway, or the Total Outdoor versions of Oxy Solve. For soot, I would recommend making the dilution for manual application stronger than what is on the label. Please try 1-part-Oxy Solve to 10-parts-water. Apply to the surface in sections so that you can rinse before the product has a chance to dry. Apply, let sit for 3-5 minutes, scrub, and rinse at highest pressure - or apply, let sit for 3-5 minutes, and pressure wash to rinse at highest pressure. If you can apply the solution with a pump-up, garden-type of sprayer and then pressure wash at high pressure to rinse, you'll be able to cover a larger area than if you use the pressure washer chemical application setting to apply the product (which sucks down product very quickly.) I hope this information helps and that Simple Green Oxy Solve does a great job on the soot and grime you are dealing with. Thanks!
Question:	How can i used this product in car engine? What step should i follow
Answer:	Wish I could tell you. It cleans great but you need to rinse it to tell. Without rinsing, in my opinion, is a waste of your time as the mess is still there.
Question:	Does anyone have a positive experience in removing OLD oil stain from concrete
Answer:	A lot of elbow grease needed. I was unable to even get dirt off my driveway. I was disappointed with this product.

• Simple Green Pro HD is your one-stop cleaner and degreaser

User questions & answers

Question:	Can this be used safely on concrete
Answer:	Yes, but it is mainly designed as a degreaser, so large scale application to a concrete driveway is not really recommended. If you are treating grease spots on concrete and are not in California (which has strict air quality laws) then you can wet the spot with water and pour a little of the concentrate right on the spot. Let it sit for a few minutes (but not dry) and scrub well with a stiff bristle, non-metallic brush. Rinse well. If the spot is an automotive fluid containing a dye, the petroleum soil may be gone, but the spot may still show. Repeat application may help fade it. If the concrete has a sealant on it, this product may weaken or remove the sealant.
Question:	Can you wash a car with it
Answer:	At a 1:10 dilution (1-part HD to 10-parts water). you can wash a car - but it won’t suds/foam like normal car wash soap. Hose off the car to remove grit and wash in sections and rinse so the cleaner doesn’t dry before rinsing. Rinse the whole car thoroughly with water when done and you may want to re-wax. A 1:10 may not be strong enough to strip wax unless you let it sit on the surface for a long time or the wax is old or thin.
Question:	Can this be used on varnished wood? My door is full of very old hair spray. Thanks
Answer:	You should be able to dilute Simple Green Pro HD at 1-part-product to 3-parts-water (or use the ready-to-use in the spray bottle) and remove old hairspray on a varnished door. Please be aware that the hairspray (most of which contain solvents or alcohol as a carrier for the other ingredients) could possibly have weakened or damaged the varnish and that cleaning it off with anything could possibly reveal that damage. Please test Pro HD on a small spot first to see if that is the case. Once you apply the solution, wait a few minutes to allow it to penetrate, and then gently wash with a non-abrasive sponge, cloth or microfiber, and then "rinse" with a damp sponge or cloth wipe.
Question:	The product says pack of 2, is that 2 of each or just the 32oz & gallon combined ? Thanks
Answer:	The 2-pack is one 32-oz spray bottle of ready-to-use Pro HD and one 1-gal Refill Bottle of concentrated Pro HD. Simple Green Pro HD can be used full-strength outside of California* and may be diluted anywhere from 1-part-product to 1-part-water all the way up to 1-part-product to 30-parts-water. The spray bottle contains a 1-part-product to 10-parts-water solution that is a very effective, and non-corrosive cleaner/degreaser. I hope that this information is helpful to you. [*Dilution of 1:3 or greater is required in California to meet air quality regulations.]

User questions & answers

Question:	Can I use this on my wheels
Answer:	Sonax wheel cleaner would be the better cleaner to deal with iron deposits from brake pads.
Question:	Is this safe on plastic covers or rubber hoses that are in the engine
Answer:	Yes it is! I have used it multiple times on my entire engine both in cold and hot temperatures
Question:	is this better than gunk engine degreaser
Answer:	I have used this product to clean a well-maintained engine bay so I can't comment on its "oven cleaner" grease cutting power but I'm confident that Sonax will not disappoint! I use several of their products and will continue to. This is a safe top shelf German car care product. I'd love to hear how it works for you. Good luck.
Question:	What are the "sensitive areas" that have to be covered? What materials will it harm
Answer:	Like with any major cleaning in the engine bay, you'll want to cover things like exposed electrical components, alternator, air intake filters, distributor caps, coils, fuse boxes, etc.

Answer:	Not sure but I would try it on an old rug first
Question:	Has anyone used this on the inside of a gas grill? Like the lid which gets very greasy
Answer:	Although I have NOT used it on the inside of the gas grill I actually used it on my Microwave/Convection oven, and it worked great, cleaned up quickly, rinsed if off several times with clear water and a paper towel, it did not affect the use at all. Hope you find this response helpful.

User questions & answers

Question:	Is this the Original or Heavy Duty
Answer:	As far as I know, it's the original.
Question:	Will this stuff eat my fan belt, and electrical wires
Answer:	Really solid question - I would definitely try to keep this away from the fan belt, but since most of your electrical wires are likely higher gauge, on the thinner side, this stuff shouldn't sit on there long enough to damage the insulation on the wires (it will evaporate away first). The plastic the insulation is made out of is pretty tough too, so again, low risk with the electrical components. With all the grooves and places for this stuff to pool on your fan belt, however, it will be able to sit there longer and seep into the belt and almost definitely weaken it.
Question:	If this gets on the car will it harm the finish
Answer:	The words painted on my engine cover did not strip off. It just loosened the grease so you can was down the engine. Your paint should be safe.
Question:	Is this water based or solvent based
Answer:	Solvent based
