P21S 14500B Bodywork Shampoo, 500 ml

I am using since last five years , result is excellent on on p21s waxed car surface.

A friend in car business uses and recommended this line of products. I bought 3 of their products and am impressed. The paintwork cleanser is amazing. I had road oil/tar spots that I was concerned about removing,but the cleanser seem to melt them away and the paint looked perfect for waxing. The wax was easy to apply (never in the sun) and polish. After completing this labor of love (my wife's car) it makes sense to preserve the finish with their shampoo. Read all instructions.Last comment: TCs Garage Parts and Acc. delivery was exceptional, much faster than I expected and packed well!

Very gentle. I first learned about this product back in 1998 on an Audi forum, and I've been using it since. The bottles with the red cap they sell on Amazon are the legit original formula P21S "Made in Germany" product. The ones I've seen in stores with the white cap bottles are made here in the US, and I've heard the formula is slightly different.

I was a little skeptical but after one wash I felt it was worth the extra money. Now, after several washes it seems the car stays cleaner looking longer and the shine compares to using compound and lots of elbow grease. I'm definitely glad I tried this product.

Great for cleaning most things off your paint. Don't expect it to get stains out which have oxidized the paint or anything like that. Great product, could be a better value if the price came down.

Great car cleaning soap - really foamy and does a great job removing dirt. The great thing about this soap is that it isn't harsh at all - and thus it doesn't affect wax - even carnauba wax that tends to easily be removed.
