Which product can be applied to each surface and which one will ruin it. Twelve materials cross-referenced with eleven products, with the usage criterion for every combination.
✓
Compatible
Recommended for this surface, following the dilutions on the technical data sheet.
!
Caution
A prior test is mandatory. Risk of loss of gloss or stripping if the contact time or the concentration is exceeded. Rinse promptly.
✕
Incompatible
DO NOT USE. High risk of irreversible damage to the surface (corrosion, acid attack, dissolution of plastics or paint).
–
Not its purpose
This is not the product’s main use, although it may not be harmful.
On sensitive surfaces (soft metals, aluminium, galvanised steel, natural stone, paint and engineering plastics) a prior test in an inconspicuous area is mandatory.
Do not let the product dry on the surface.
The Antifoam does not appear in the compatibility table because it is not applied to surfaces: it is an additive that goes into the machine tank or the water circuit.

Frequently asked questions
Questions we are asked every day
Responding to an incident
As soon as possible, and that is not a figure of speech: with every day that passes, the damage stops being superficial. After a fire, smoke from plastics and wiring deposits hygroscopic acid chlorides, which draw moisture from the air and keep an acidic film on the metal: corrosion advances on its own even a week after the fire is out, and on bare steel in a humid environment pitting starts within hours. At the same time, soot works its way into the pores of paint, plaster, timber and exposed concrete until it can no longer be cleaned and has to be replaced. After a flood the clock runs the same way, with mould on top: in high humidity it colonises within 24 to 48 hours. The priority is to neutralise and dry as soon as possible; fine cleaning can wait, the progress of the damage cannot.
With whatever cannot be undone. First, safety: isolate the power and assess the structure. Second, dry removal of soot before wetting anything, because a damp cloth turns vacuumable dust into a permanent stain. Third, neutralise the acidic residue with an alkaline product such as PDR-AC12 Super Cleaner to halt corrosion, even if the fine cleaning comes later. In parallel, dry the building with dehumidification and forced ventilation. The finish and the protector come at the end, once the damage has been stopped.
No, and it is the mistake that ruins the most jobs. The industry standard, ANSI/IICRC S700, classifies residue by its origin because each type calls for different chemistry. Dry soot, from fast-burning paper or wood fires, is loose dust: remove it dry and a neutral cleaner is enough. Wet or greasy soot, from the slow combustion of plastics and wiring, is sticky and only a solvent base such as the PDR-TC7 will dissolve it. Protein residue, from kitchen fires, is almost invisible but varnishes surfaces and smells strongly: it calls for a powerful alkaline degreaser such as the PDR-EDG14. And fuel soot, typical of a boiler puff-back, needs solvent first and alkaline afterwards. Applying a water-based product to greasy soot does not clean it: it spreads it and sets it.
Only with the two products designed for it, and always with the equipment de-energised and disconnected from the mains. If the contamination is soluble or hygroscopic, clean with PDR-EWC7 Electric Watery Cleaner and then rinse with PDR-ERWC Electric Rinse, which lifts salts and detergent residue. Before reconnecting, complete drying must be assured: residual moisture causes faults and short circuits.
Because fire smoke deposits acid chlorides that keep attacking the metal after cleaning. The PDR-GLOSS Preserver seals the cleaned surface and stops that late rusting, which is the usual reason an apparently sound job falls apart a few weeks later.
Choosing a product
Always start with the PDR-PC7 Multi Cleaner. It is the most widely compatible product in the range: suitable on eleven of the twelve surfaces in our table, including marble, lacquered finishes, aluminium and painted walls. The only exception is electrical panels and components, which take only the PDR-ERWC and the PDR-EWC7. If the PC7 does not deal with the soiling, step up the strength, checking the compatibility table before you change product.
No. Neither the PDR-SC1 Tile Cleaner nor the PDR-DR1 Deruster should be applied to marble, limestone, terrazzo or any calcareous stone: the attack is immediate and irreversible. For those surfaces, use the PDR-PC7 Multi Cleaner or the PDR-GC7 Glass Cleaner.
The PDR-TC7 Turbo Cleaner is solvent-based and attacks combustion residue —soot, carbon deposits, tar, burnt oils— where water cannot get in. The PDR-EDG14 Extreme Degreaser is alkaline at pH 13–14, water-based, and its territory is industrial grease and hydrocarbons on steel and iron. The EDG14 must not be used on aluminium, painted or lacquered surfaces.
Eleven of the twelve products are approved for use in the food industry, provided the appropriate rinse is carried out after application and no residue is left on food-contact surfaces. The only exception is the solvent-based PDR-TC7 Turbo Cleaner, whose technical data sheet does not state that suitability. Each technical data sheet states this explicitly.
For both. The range comes out of damage restoration, which is the most demanding use, but the same products work in day-to-day industrial maintenance: the PDR-SC12 for scrubber dryers, the PDR-EDG14 for degreasing units and machinery, the PDR-PC7 for general cleaning and the PDR-GC7 for glazing. What changes is the dilution, not the product.
Use and dilution
No. An acid and an alkali neutralise each other: you lose both products and, depending on the formulation, you can generate gases. The correct procedure is to apply one, rinse, and move on to the next. Nor should you mix two alkalis or "boost" one product with another: the dilutions on the technical data sheet are already worked out.
Always start with the mildest dilution stated on the technical data sheet and step it up only if you need to. A second pass is quicker than repairing a stripped surface. Applying neat a product that the data sheet dilutes 1:20 does not clean twenty times better, but it can damage the material.
Documentation and safety
On each product page of this website, under the "Safety data sheet" button. They are safety data sheets compliant with Regulation (EU) 2020/878, downloadable as PDFs without registering. The technical data sheet, with dilutions and directions for use, sits next to it.
Six carry the signal word "Danger": PDR-TC7 Turbo Cleaner and PDR-ERWC Electric Rinse (highly flammable liquids), PDR-DR1 Deruster, PDR-SC1 Tile Cleaner and PDR-EDG14 Extreme Degreaser (they cause severe skin burns and eye damage), and PDR-SC12 Scrubber Cleaner (serious eye damage). Three carry "Warning": PDR-AC12 Super Cleaner, PDR-PC7 Multi Cleaner and PDR-EWC7 Electric Watery Cleaner. And three are not classified as hazardous under Regulation (EC) 1272/2008: PDR-GLOSS Preserver, PDR-DF7 Antifoam and PDR-GC7 Glass Cleaner. Each product page shows its full H and P statements.
Generally between 5 °C and 25 °C, in a dry, ventilated place, protected from direct sunlight, upright and with the container tightly closed. Solvent-based products must also be kept away from any ignition source. The exact range for each product is on its technical data sheet, because some tolerate up to 35 °C or 40 °C.
They are never poured into sewers or watercourses. Waste and empty containers are handled in accordance with local and national legislation and with Directive 2008/98/EC on waste, through an authorised waste contractor.
Ask us about each specific product. What is decisive is storage: outside the stated temperature range, with the container opened or exposed to direct sunlight, a product can lose effectiveness long before any printed date.
Buying and supply
Yes, at no cost. Describe the incident or the type of soiling on the contact form and our technical team will specify the product, the dilution and the application procedure. We reply within one working day.
20-litre drums for Turbo Cleaner, Super Cleaner, Deruster, Extreme Degreaser, Multi Cleaner, Tile Cleaner and Gloss Preserver; a 10-litre drum for Scrubber Cleaner; 5-litre drums for Electric Rinse, Glass Cleaner and Electric Watery Cleaner; and a 1-litre container for Antifoam. The Turbo Cleaner comes in a metal drum because it is a solvent-based product.
Prices are on request, because they depend on the volume and on how regular the supply is. Tell us which products you need and in what quantity and we will send you a firm quotation; if it is a one-off need for an incident, we also arrange urgent supply.
Tell us about the job and we will consider it. For high-volume products such as the Multi Cleaner or the Scrubber Cleaner, a targeted trial on your actual surface usually makes more sense than a generic sample: we will specify the dilution and the procedure so that the test is conclusive.
