I've got a pressure washer and ordered an undercarriage attachment. I live in MD where I have to deal with a lot of salt on the roads. Can i get away with just using water or do i need an APC or other cleaner? I searched multiple forums and there are a million APC's that people suggest. I just want something to rinse salt/mud and not damage the undersurface. Also something simple that I don't have to dilute would be great. I get nervous thinking about diluting because i don't want to do damage. I have simple green lying around.

Can i get away with:
water alone?
car wash soap via a foam cannon or the pressure washer?
or hand spray an APC spray bottle that i can then rinse off?

Any suggestions would be appreciated, but really looking for what product is easiest/cheapest to use. Thanks.
 
I'd try Pearl from P&S

Thanks. So could i get away with any reputable car shampoo (i have some chemical guys soap)?
 
Anything will work because your just trying to keep it clean, the effort is worth it

I can not see where it would hurt. P&S Pearl shampoo is an excellent, under the radar car soap. For undercarriage washing, I might be inclined to try a product like AutoFoam from Bilt Hamber. It has outstanding cleaning power, and also corrosion preventatives (I believe).
 
Im in a similar boat as OP, but I don’t have the nice tools: pressure washer, undercarriage attachment. I need to do SOMETHING though. I’m thinking maybe spray an APC, hose rinse, spray Feynlab Pure Rinseless (strong Rinseless wash), hose rinse. Unfortunately I don’t have a foam gun of any type (only an IK Foam sprayer) to use a regular wash and I have no plan of agitating with a sponge.

I’ll also be jacking up one side of the card with a hydraulic garage jack to get the spray and rinses done since I don’t have a nifty undercarriage attachment.

Anyone have any better recommendations than the APC/strong RW/hose rinse method I’m planning?

I have an electric washer that has a reservoir for soap ( not at the tip of the nozzle) and I also have an undercarriage attachment. I filled the reservoir with a strong pre-wash solution (powerclean, 3D pre-rinse, or purple power vehicle and boat soap) and utilize the carriage attachment to get to all the nasty bits underneath. Let it dwell for a little bit then power-rinse it down using the same carriage attachment with water. If it is really bad... I would use the carriage attachment and try to knock off the big chunks first then proceed as stated above.
 
I use the poor man's method. I just spray my APC all over the undercarriage. Then rinse with a strong jet of water.

I was going to order the UNDERWASHER. A tool that you hook up to your regular water hose. But i think they are long out of business. Too bad.

Figured they were out of business? Tried to contact them awhile back. No response. I just E-mailed them again today. Did not want to place a order and have it in limbo or worse. I'll let you know if i hear anything...

Looks like if you google "undercarriage pressure washer" or "Pressure washer water broom" there are definitely options out there. A little more money than the Underwasher, but also a bit more robust looking. Ride height can definitely be a factor with some of them (for us non-truck folks. :D )
 
Alrighty then. Just got a response from them. The units are indeed current and for sale. I must have used a bad contact E-mail when i first tried to contact them about a month ago.

Going to have to look them over again this weekend and order one. I am thinking the LONG version would fit my needs.

Ive also been in touch with them since yesterday. So I think it’s legit.
 
I received the Ryobi water broom as a present but haven’t had a chance to use it yet. Will definitely be using it after this spring due to the winter salt. Plan to spray a couple APCs and rinse well between each.
 
I just realized the underwasher is just for hooking up to your hose, not a pressure washer.

Not to be a negative nancy, but boy it seems like you could make something like this yourself with some PVC pipe, cement, and a hose fitting. Start with small holes and work your way up to find the right spray pattern. I guess at least they're not charging a ton of money for it.
 
I was looking at the attachments for a PW but I only have a 1.2 GPM 1700.

:iagree:


Then get yourself some of the same Salt-Away product to use with it.

The price of the Salt-Away kit isn’t bad when searching for the chemical and mixer externally... shipping pushes it slightly higher but I was trying to get them to do combined shipping.

I have no problem putting down $20-65 for a professionally built product versus pissing my wife off hiding in the garage cutting and sealing PVC that will probably start leaking after 7 uses.
